Full loading chart for CPL, TPL, QPL, FPL, and UDL. Loading conditions: The truss is supported or suspended at both ends; values apply to static loads only; loads are applied at nodes; spans may be assembled from multiple truss lengths; and the truss self-weight is included. Applications in the Live Events and Entertainment Industry The S-RTW 145 is designed for projects where conventional aluminum trusses may no longer provide an efficient solution in terms of load capacity or span. In large-scale stage designs, the truss can serve as a primary beam for roof grids, supporting loads from secondary trusses, point hoists, LED screens, and audio systems. Concert and Festival Stage Roofs Creates long-span main beams for canopies, lighting grids, and suspended loads within the roof system. Heavy-Duty Main Grids Supports lighting systems, line arrays, video equipment, moving equipment, and scenic elements simultaneously. PA Wings and Video Wings Can serve as a horizontal beam or primary structural member for outdoor sound towers and LED screen structures. Large-Scale LED Screen Structures Supports the self-weight of LED screens and their suspension systems, with wind loads to be addressed through project-specific structural calculations. Semi-Permanent Structures Suitable for stages installed for extended periods, performance venues, or specialized structures requiring high stiffness. Multi-Directional Roof Grids The webbing pattern and horizontal connection holes support the arrangement of cross trusses, nodes, and auxiliary connections. Integration with Steel Roof Systems The MILOS S-MR10 datasheet demonstrates how MILOS applies high-strength steel trusses to large-scale stage roof systems, combining towers, canopies, PA wings, and backstage areas. When the S-RTW 145 is incorporated into a specific roof system, the complete geometry, wind loads, ballast, guy wires, and foundations must be evaluated as an integrated structural system. Structural Calculation and Safety Requirements Standard design factors: According to MILOS notes, to comply with BS 7905-2, ANSI E1.2-2006, or EN 17115, the values shown in the loading chart must be multiplied by 0.85 . Configurations that differ from the loading-chart conditions must be separately reviewed by MILOS or a qualified structural engineer. Conclusion The MILOS S-RTW 145 / S-M1450 Rect is a high-strength steel truss solution developed for heavy-duty stage structures and long-span applications. With a 1,450 × 770 mm cross-section, a published maximum span of up to 50 m, and integrated features for rigging and logistics, the system is particularly suitable for roof systems, main grids, PA wings, video wings, LED screen structures, and large-scale concert and festival stages. However, the load values shown in the loading chart are for reference only and apply under the specific conditions defined by the manufacturer. For actual projects, the span, loads, suspension points, wind loads, ballast, towers, guy wires, foundations, and overall structural configuration must be evaluated together. Applicable design factors and operating conditions must be followed in accordance with the relevant technical documentation. Any configuration that differs from the published loading-chart conditions should be reviewed, calculated, and approved by MILOS or a qualified structural engineer before being put into service.

Aluminum Truss
What Are the Technical and Material Characteristics of Aluminum Truss? The primary material used in these aluminum truss systems is EN AW-6082 T6 extruded aluminum alloy, fabricated using TIG welding processes certified to the international EN ISO 3834-2 standard by TÜV SÜD. The design features four main chord tubes (Ø50 × 4 mm) combined with diagonal bracing members (Ø30 × 3 mm) to create a network that optimally distributes mechanical stress. Each truss segment is equipped with EN AW-2011 T8 conical connectors, joined via high-strength steel pins. Technical Specification Declared Standard Value Basis for Assessment / Applicable Standard Main tube aluminum alloy EN AW-6082 T6 (Ø50 × 4 mm) High tensile strength and yield strength Shear-resistant bracing system Aluminum tube Ø30 × 3 mm; brace angle from 55° Ensures shear force transmission along the truss body Module connection joint EN AW-2011 T8 Conical Connector Safety locking pin (DIN EN ISO 8752) Material density Approx. 2.7 g/cm³ (one-third that of steel) Optimizes touring transport costs Welding certification standard EN ISO 3834-2 certified by TÜV SÜD Ensures weld penetration and strength Structural design standard Eurocode 9 (DIN EN 1999-1-1), DIN EN 13814 Structural safety verification for temporary structures Aluminum's low weight cuts the static load exerted on hoist systems and workshop ceiling structures by half. Prefabricated modules available in standard lengths of 1, 2, and 3 meters allow for flexible assembly tailored to any stage area. Its natural oxidation resistance ensures the aluminum surface retains its luster throughout years of outdoor use. How Are Aluminum Truss Span and Load Capacities Calculated? Aluminum truss load tables are established in accordance with the DIN EN 1990 standard, featuring a strict deflection limit of L/150 to ensure lighting fixtures remain stable. At a 12-meter span, the box truss system safely supports a center-point load of up to 1,383 kg with a deflection of only 26.8 mm. When the span is extended to 20 meters, the structure maintains stability under a 736 kg point load, fully meeting the requirements for suspending show equipment. Rigging engineers are required to suspend loads at the connection nodes—where diagonal bracing meets the main chord tubes—to eliminate local bending moments. The use of secondary safety lines keeps the aluminum beams aligned, preserving the safety factor throughout the performance. Load data accounts for the beam's self-weight, enabling technicians to devise precise load suspension plans. Advantages of Using Aluminum Trusses in the Events Industry The conical connector system allows technicians to join truss sections rapidly using only a handheld copper hammer. Its lightweight nature allows the crew to easily carry, position, and dismantle the system with minimal physical effort. Consequently, the stage setup process is significantly faster compared to traditional bolted structures. The four-sided chord tube design offers numerous mounting points for clamps holding moving head lights, line array speakers, and multi-layered LED screen frames. An elegant silver metallic finish or a matte black powder coating lends a modern aesthetic to the stage. This high aesthetic appeal allows the truss framework to blend seamlessly into the performance environment. Periodic Technical Inspection Process for Aluminum Trusses Technicians must thoroughly inspect TIG weld surfaces and the roundness of pin holes before the equipment leaves the warehouse. Cleaning dust and grit from the conical connectors helps maintain the integrity of the metal joints. Periodic checks for beam straightness ensure the structure consistently maintains its rated load-bearing capacity. Operators should neatly stack aluminum frames onto specialized wheeled racks to prevent chord tube deformation during long-distance transport. Careful storage ensures long-lasting durability and complete peace of mind for every performance. Evaluating the Investment Value of Aluminum Truss Systems Aluminum truss systems represent a fixed asset that offers a rapid return on investment for event organizers and theaters.

360° Rotating Motor
Equipment Overview The Giga Rotator by Wahlberg Motion is a heavy-duty rotary axis designed for suspended applications in stage, event, and performance environments. The unit is mounted to a load-bearing structure using four slim eye couplers , while the payload is connected to the lower rotating assembly. Its drive system enables objects to rotate around the suspension axis across a wide speed range, from slow movements at 0.02 rpm to speeds of up to 10 rpm . For performance configurations, the unit can be installed in either a vertical orientation or a horizontal orientation at 90° to the ground , allowing the projection surface to face the audience or creating dynamic spatial transformation effects. Rotation position, speed, and direction are controlled via DMX. The datasheet specifies 0.1° angular control resolution , making the unit suitable for motion sequences that require precise and repeatable positioning. Integration Principle The load-bearing suspension structure supports the weight of the unit and the performance payload. The motor and transmission system generate rotational torque around the vertical axis of the suspension assembly. The slip ring transfers 10 A per connection and allows Ethernet/DMX signals to pass through the rotating section, helping prevent cable twisting. The DMX controller sends position, speed, and cue commands. Motion should be tested under actual operating load conditions before deployment. Technical Specifications Specification Value Model DMX Rotator 1000 Item No. 282 Dimensions 485 × 485 × 244 mm Power Supply 100–240 VAC, 50/60 Hz Power Consumption 350 W (3.5–1.5 A) Power Input/Output Neutrik powerCON TRUE1 NAC3PX (F/M) Control Protocol DMX512/1990 + DMX512-A DMX Channels Used 7 channels DMX Input/Output 5-pin XLR (F/M) Thru Connection – Input powerCON TRUE1 (M) and EtherCON (F) Thru Connection – Rotating Section powerCON TRUE1 (F) and EtherCON (F) Power Thru 10 A per connection, 2.5 mm² conductor cross-section Signal Thru 100 Mbit Ethernet or DMX (optional RJ45 converter) Rotation Unlimited / continuous rotation Working Load – Downward 1,000 kg (2,204.6 lb) Working Load – Upward 1,000 kg (2,204.6 lb) Working Load – Horizontal Pending – not specified in the datasheet Rotational Speed 0.02–10 rpm Noise Level 50 dB at 1 m Ambient Temperature 5–40 °C Unit Weight 64.5 kg (142 lb) Mounting Clamps 4 × slim eye couplers, 42–52 mm (2 in) Duty Cycle 100% Control Characteristic Angular control with 0.1° accuracy Dimensions and Mechanical Interface Dimension / Mechanical Specification Value Overall Dimensions 485 × 485 × 244 mm Outer Housing Diameter Ø485 mm Reference Diameter – Top Surface Ø459 mm Top Hole Pattern Diameter Ø13 mm Bottom Connection Pattern Ø374 mm and Ø405 mm Threaded Connection Shown on Drawing M12 Hole Reference Angle 15° System Connections The unit receives DMX via a 5-pin XLR interface and uses 7 DMX channels . EtherCON and powerCON connections are routed through the rotating section, allowing power and signal transmission to equipment mounted on the rotating payload. This configuration is particularly useful for lighting fixtures, displays, cameras, and communication devices that need to remain operational while rotating. Performance Applications The Giga Rotator expands the range of motion possibilities for large suspended objects. Instead of relying solely on vertical lifting and lowering, the system can dynamically change the viewing direction, display surface, and form of a performance object over time. A 90° horizontal rotation can create a distinctive visual effect while remaining easy to synchronize with lighting, audio, video, and timecode. Operational Benefits A wide speed range supports both subtle movements and rapid scene transitions. Unlimited rotation eliminates travel limitations in designs requiring repeated multiple rotations. Power and signal pass-through through the rotary axis helps reduce the risk of cables wrapping around the structure. 0.1° angular control resolution supports precise and repeatable positioning.

Suspension System Sliding Rail
System Overview The DST52 is a rail-integrated stacking truss system developed for heavy-duty stage motion applications. It can be used to move LED screens, stage scenery, projection screens, and lighting assemblies horizontally. By adding a hoist or rotating module, the same platform can also provide lifting and lowering as well as 360° rotation . The DST52 is available in two rail configurations: straight and curved . A key feature of the DST52 is its stackable trapezoidal cross-section . The modules are connected using fork connections , allowing the trolley to be installed before the truss is suspended. This modular structure helps reduce setup time, minimize storage volume, and support the logistical requirements of touring productions. Technical Data – DST52 Rail Item Specification Structural type Trapezoidal-section stacking truss with dual rails Overall dimensions (H × W) 520–762 × 520 mm Centre-to-centre dimensions 470–712 × 470 mm Main chords EN AW-6082 T6 extruded aluminium, Ø50 × 4 mm Bracing tubes EN AW-6082 T6 extruded aluminium, Ø30 × 3 mm Fork connection EN AW-6082 T6 aluminium Rail configuration Straight or curved; trolley can operate on both types Finish Standard aluminium; dark grey or other colours available on request Standard Rail Sections LITEC Code Length / Geometry Weight STK52R100 100 cm 38.0 kg STK52R150 150 cm 51.0 kg STK52R300 300 cm 88.1 kg STK52RT100 100 cm 54.4 kg STK52RT150 150 cm 69.9 kg STK52RT300 300 cm 116.6 kg STK52RC Length ≤300 cm; radius ≥400 cm According to configuration Technical Data – STK52MTD2K The STK52MTD2K is a heavy-duty motorised trolley designed for the DST52 system. The trolley runs inside the dual-rail track and provides linear motion for the connected load, either in combination with a slave trolley or an auxiliary structure. This version is specifically characterized by a 1-ton WLL on 52R rail , a maximum speed of 21 m/min , and a Kinesys control interface .

For moving loads, the design must account for dynamic factors, acceleration and deceleration distances, eccentric loading, and actual suspension conditions . Control and Stage Applications The Kinesys control interface allows the trolley to be integrated into a stage motion control system, enabling the programming of position, velocity, and synchronized movement cues . In a complete system, position feedback, software limits, mechanical end stops, and emergency stops should be designed as independent layers of protection. The compiled technical information also indicates that DST modules can be managed by other commonly used control systems available on the market; however, the interface configuration must be verified for each specific project. Moving LED Screens Move LED screens laterally to open the stage, change the stage layout, or create dynamic reveal effects. Scenery and Projection Screens Move stage scenery, portals, projection screens, or decorative frames over long travel distances. Touring Productions The stackable rail and foldable dolly configuration help optimize storage volume, simplify modular transportation, and accelerate setup on touring productions. Expandable Motion Systems Combine the system with a hoist for lifting and lowering or with an STK52MR module for 360° rotation. A dedicated technical assessment is required for combined configurations. Key Advantages 1,000 kg WLL for the motorised trolley on the 52R rail configuration. Maximum speed of 21 m/min , suitable for large-scale stage transitions. Straight and curved rail configurations to accommodate different stage geometries. Modular and stackable design , optimizing transportation and storage. Expandable architecture , allowing the system to evolve from Move to Move + Lift or Move + Turn configurations. Conclusion The DST52 Rail and STK52MTD2K Motorised Trolley form a modular heavy-duty stage motion platform suitable for applications requiring the long-travel movement of suspended equipment and structures. The DST52 supports both straight and curved rail configurations , while its stacking design helps optimize transportation and storage. The STK52MTD2K provides a 1,000 kg WLL and a maximum speed of 21 m/min , meeting the requirements of large-scale stage motion applications. The Kinesys control interface also enables the trolley to be integrated into a motion control system for programming position, velocity, and synchronized movement cues. When lifting or rotation is required, the DST52 platform can be further expanded with suitable modules. However, for every real-world configuration, equipment selection, load capacity, connections, supporting structures, and safety systems must be engineered and verified according to the technical documentation and requirements of each individual project , particularly when the system operates with moving loads.

Combined Rotary and Lifting Stage
Combined 360° Rotation and Independent Vertical Lifting ROTATIONAL MOTION LIFTING MOTION CONTROL Ø4–18 m · 1–6 rpm Multiple independent lift modules Cue · Position · Speed · Timecode Key Value: A single stage system can simultaneously rotate the overall stage while changing the elevation of individual areas, enabling continuous scene transitions without interrupting the performance. What Is a Rotary Stage Combined with Programmable Stage Lifts? Combining a rotary stage with programmable stage lifts introduces a new level of flexibility to motion-stage design. The modular rotary stage can be configured from approximately 4 m to 18 m in diameter , using multiple coordinated 2 HP motors with an adjustable rotational speed of approximately 1–6 rpm . Within the circular structure, multiple programmable stage-lift modules can be arranged as independent zones, allowing performers, props or sections of the scenery to move vertically while the entire stage continues to rotate. Each stage-lift module can be customized according to project requirements , including its shape, platform dimensions, lifting stroke, working load, operating speed and number of drive points. The motion-control system can program target position, speed, acceleration, timing, cue and timecode, allowing the lift modules to coordinate with the rotary movement according to a unified show sequence. The working load of each lift module is calculated after deducting the self-weight of the moving structure. Eccentric loads, dynamic factors and safety margins must also be taken into consideration. This configuration creates a 360° stage effect , continuous scene transitions and real-time elevation changes during a performance. The director can raise a singer from below the stage, rotate the band toward the audience, reposition props or create multiple spatial layers without interrupting the show. This configuration is suitable for concerts, game shows, festivals and large-scale stages requiring complex motion capabilities. Technical Data – Modular Rotary Stage Specification Technical Data Notes System type Modular rotary stage Reconfigurable according to project requirements Diameter Approximately Ø4 m to Ø18 m Final dimensions determined by venue layout and load requirements Structure Fan-shaped modules, radial beams and concentric rings Demountable for transportation Rotational speed Approximately 1–6 rpm, adjustable via PLC 6 rpm is not applicable to every diameter Rotation direction Clockwise/counterclockwise; 360° rotation according to configuration Direction changes managed through controlled acceleration/deceleration profiles Control PLC Supports cue and show control Surface finish Plywood, vinyl, carpet or other finishing materials Selected according to the artistic design Safety E-stop, speed limits, pinch-point protection and drive monitoring To be assessed and validated for each project Speed Consideration: At Ø18 m , 1 rpm corresponds to an approximate edge speed of 0.94 m/s , while 6 rpm corresponds to approximately 5.65 m/s . Therefore, the maximum rotational speed must be limited according to the stage diameter, load conditions and performer location. Technical Data – Customized Programmable Stage Lifts Specification Reference Data Notes System name Customized programmable stage lift Individually designed for each project Platform shape Circular, square, rectangular or special shapes Coordinated with the rotary-stage modules Platform dimensions Customized according to the stage design Final dimensions determined by drawings and installation space Lifting stroke Customized according to the required elevation Dependent on structural configuration and available technical space WLL Calculated according to the actual module load Includes performers, props and concentrated loads Lifting/lowering speed Programmed and limited according to the application Smooth motion is prioritized when performers are present Number of lift modules One or multiple independent modules Can operate individually or in groups Number of drive points Designed according to dimensions and load distribution Ensures synchronized elevation Position feedback Encoder/position sensor Monitors elevation and positional deviation Programming Position, speed, acceleration, timing, cue/timecode Enables coordination of multiple motion axes Useful load capacity Lifting capacity after deducting the self-weight of the moving structure Accounts for eccentric loads and dynamic factors Safety equipment E-stop, travel limits, anti-drop protection and synchronization monitoring Final configuration determined through risk assessment Load Principle: The WLL (Working Load Limit) of each stage-lift module must be established based on the structural design, number of drive points, self-weight, load position, dynamic loads and applicable safety factors. A single standardized load rating should not be applied to all module sizes. Conclusion A rotary stage combined with programmable stage lifts expands the possibilities of motion-stage design by integrating two primary movements: full-stage rotation and independent vertical lifting of individual areas . With a modular structure, customized lift modules and PLC-based control, the system can be engineered according to the specific venue layout, load requirements, lifting stroke, operating speed and motion sequence of each project. For stable and safe operation, parameters such as rotational speed relative to stage diameter, working load limit (WLL), eccentric loads, dynamic loads, number of drive points, elevation synchronization and protective devices must be calculated and validated according to actual operating conditions. In particular, a fixed rotational speed or load rating should not be applied universally across all configurations. When properly designed, programmed and controlled according to the required technical specifications, the system can deliver 360° scene transitions, dynamic elevation changes and continuous spatial reconfiguration without interrupting the performance. This makes it a suitable solution for modern stages requiring advanced mechanical motion, automation and show-control synchronization .

Stage Rotating Platform
What Is a Modular Rotating Stage? The modular rotating stage supplied by Melody Productionworx is a flexible motion-stage solution developed to accommodate different event scales and production requirements. Instead of manufacturing a fixed rotating stage for each project, the system uses fan-shaped modules, radial beams, and concentric structural rings. Starting from a configuration of approximately 4 m in diameter, the stage can be progressively expanded to 18 m by adding the appropriate modules, rails, wheels, and drive units. The drive system uses multiple 2 HP motors working together. This multi-drive configuration distributes pulling force around the circumference, reducing concentrated loads and allowing the drive capacity to be scaled according to the stage diameter, overall weight, and performance load. The motors are controlled through variable frequency drives (VFDs), combined with PLC control and encoders to provide smooth motion, variable speed control, forward and reverse rotation, and precise stopping according to programmed show cues. The rotation speed can be adjusted from approximately 1 rpm to 6 rpm. However, the actual operating speed is always determined according to the stage dimensions, load conditions, performance requirements, and applicable safety considerations. One of the system's key advantages is its flexibility for both production and repeated use. The same set of modules can be configured for concerts, game shows, product launches, automotive exhibitions, fashion events, or performing arts productions. The detachable construction facilitates transportation, reduces installation time, and allows individual components to be serviced or replaced when required. The stage surface can also be finished with a range of materials to match the overall visual design of the production. With the ability to scale to large diameters, the rotating stage can transform not only a single prop or performance element but the entire performance space into an active staging component. Scenic elements, performers, or products can be brought into the audience's field of view in sync with the show sequence, creating a 360° presentation effect and expanding creative possibilities for directors and production teams. Each project is individually engineered according to the required load capacity, venue layout, operating speed, staging concept, and safety requirements. This ensures that the system delivers the desired performance effect while maintaining controlled and predictable operation. Solution Overview The modular rotating stage is a motion-stage system developed for concerts, television productions, festivals, exhibitions, and live events that require real-time changes in spatial configuration. Unlike a fixed rotating stage designed for a single diameter, the system uses fan-shaped structural modules, radial beams, and concentric structural rings. This allows the stage diameter to be configured from approximately 4 m to 18 m according to the venue layout, load requirements, and staging concept. Each configuration consists of a central hub, modular structural frames, support wheels, running rails, and drive assemblies. When a larger diameter is required, the technical team adds outer modular rings, extends the rail system, and installs additional 2 HP motors to maintain adequate traction and distribute torque evenly around the circumference. Key Technical Specifications Item Technical Description Configurable Dimensions Diameter configurations from approximately 4 m to 18 m; the final diameter is determined according to the approved layout drawings. Modular Structure Fan-shaped frames connected to form concentric rings; detachable for transportation and reconfiguration. Reference Frame The 18 m reference drawing specifies 40 × 80 × 1.4 mm rectangular steel tubing; final material dimensions are subject to structural load calculations. Running Rails The reference drawing uses 3 mm-thick sheet-metal rails; rail flatness, joint conditions, and wear resistance must be verified for each installation. Drive System Multiple 2 HP motors (approximately 1.5 kW per motor), arranged according to the stage size and load requirements. Rotation Speed Adjustable from approximately 1 rpm to 6 rpm through VFD control and programmed motion control. Rotation Direction Clockwise and counterclockwise rotation; direction changes must be performed through a controlled deceleration and stopping profile. Stage Surface Finish Can be finished with plywood, steel, vinyl, carpet, or other decorative materials suitable for the stage design. Control System PLC/VFD, encoders, and safety interlocks; programmable operating cues can be integrated into the show control sequence. Modular Construction and Scalability Scalability is one of the system's core advantages. The structure is divided into several functional layers: Central Hub and Positioning Assembly: Establishes the rotational center, maintains concentricity, and carries part of the radial load. Radial Beams: Distribute loads from the stage surface toward the supporting rings and provide the primary structural framework for the fan-shaped modules. Concentric Structural Rings: Added progressively to increase the stage diameter. The 18 m reference drawing shows ring positions at approximately 4, 6, 8, 10, 12, 14, and 16 m before reaching the final outer diameter. Stage Deck Modules: Fan-shaped deck panels installed on the structural frame, allowing the deck surface and finish to be removed, replaced, or reconfigured. Support Wheels and Running Rails: Carry vertical loads, maintain the required deck elevation, and provide a stable rotational path. Drive Assemblies: 2 HP motors, gearboxes, and drive wheels distributed at multiple locations to share the required torque. Advantages of a Modular Rotating Stage Scalable Configuration: A single modular system can serve multiple event formats instead of requiring a dedicated fixed rotating stage for each project. Optimized Investment: Structural frames, rails, wheels, and drive units can be reused and expanded according to the requirements of each project. Efficient Transportation: Fan-shaped modules and detachable beams are easier to package and transport than a monolithic structure. Faster Installation: Components can be labeled and assembled ring by ring, facilitating on-site installation and progress control. Simplified Maintenance: Individual motors, wheels, rails, and structural modules can be inspected and replaced independently. High Visual Impact: Supports scene transitions, performer rotation, moving props, display vehicles, product presentations, or rotation of the entire performance space. Applications in Live Events and Entertainment A rotating stage creates continuous movement without requiring camera positions to be changed or scenic elements to be dismantled between performance segments. In concerts, the system can rotate bands, performers, props, or secondary stage platforms to create dynamic 360° viewing angles. For television productions and product launches, the rotating stage allows cameras to capture multiple viewing angles while turning vehicles, products, or models into an active part of the presentation. With a large-diameter configuration, the stage can also be divided into multiple scenic zones, allowing different environments to be brought into the audience's field of view in sequence. Conclusion A modular rotating stage provides a more flexible alternative to a fixed rotating stage by allowing the system to be dismantled, reconfigured, and expanded according to individual project requirements. From approximately Ø4 m to Ø18 m, the system can be engineered with the appropriate number of modules, structural rings, support wheels, rails, and drive assemblies based on the actual load conditions and venue layout. The combination of modular mechanical construction with PLC/VFD and encoder-based control enables precise management of rotation, speed, and direction according to the show sequence. This makes the solution suitable for stages that require 360° movement, flexible scene transitions, and large-scale visual effects. Each system should be individually engineered and verified according to the required load capacity, operating speed, venue layout, and safety requirements before being put into operation.

Rail-Guided Recessed Stage Lift
Scope and Intended Use The proposed system is a recessed stage lift installed within a technical pit. When in the lowered position, the platform is located below the stage floor level. When fully raised, the platform is aligned flush with the stage floor, allowing props, equipment, or performers to be brought to the performance position. Applications: Performance stages, studios, multipurpose rooms, and performance areas where the lifting mechanism needs to be concealed. Operating mode: Operator-controlled raising/lowering. The system must not operate automatically when the operating area has not been secured. WLL 250 kg: Defined as the useful load uniformly distributed across the platform, excluding the self-weight of the platform and moving mechanism. Limitation: The system must not be used as a public passenger lift. If performers are to be lifted, an additional risk assessment, an independent fall-arrest system, and compliance with applicable regulations and standards are required. Preliminary Technical Specifications Parameter Preliminary Value Status Overall frame dimensions 2,000 × 2,000 mm As per drawing Usable platform dimensions Approx. 1,600 × 1,800 mm As per drawing Lifting stroke 2,000 mm As per drawing Base assembly height Approx. 240 mm As per drawing WLL 250 kg, uniformly distributed load As required Speed 10 m/min (0.167 m/s) Assumed – to be confirmed Travel time for 2 m Approx. 12 seconds Calculated from speed Motor shown on drawing 1 HP ≈ 0.75 kW Requires verification Main structure 40 × 80 mm and 50 × 100 mm box sections As per drawing Drive system Motor + gearbox + twin chain + gear/rack drive on both sides As per drawing Guidance system Guide rollers at the corners As per drawing Power supply / duty rating Not yet specified To be defined Mechanical Construction Assembly Function / Requirement Fixed pit frame Provides the guide rails, accommodates lateral loads, and connects to the stage structure. Lift platform Constructed from 50 × 100 mm box sections, supporting the finished surface and transferring loads to the drive assemblies on both sides. Geared motor Generates the lifting torque; an electromagnetic brake motor with variable frequency drive (VFD) is recommended. Twin shaft / chain drive Distributes motion synchronously to both sides to minimize platform tilting. Gear and rack mechanism Converts rotary motion into vertical linear motion. Guide rollers Restrict lateral movement, maintain the required clearances, and prevent jamming. 100 × 150 × 10 mm mounting plate Connects the rack to the frame; dimensions and welds must be verified for load-bearing capacity. Operating Principle Command input: The PLC checks the E-stop, technical pit/door status, sensors, and brake condition. Brake release and acceleration: The VFD controls motor acceleration according to a predefined ramp to minimize shock and vibration. Torque transmission: The gearbox transfers torque to the twin shaft/chain drive, driving the gears on both sides. Synchronized lifting/lowering: The gears engage with the racks while the guide rollers maintain the platform in a level position. Deceleration and stopping: Position sensors initiate deceleration before reaching the floor level, while limit switches ensure accurate stopping at the operating limits. Load holding: The motor brake engages, while an independent anti-fall mechanism provides protection in the event of a system failure.

It enables performers, stage props, musical instruments, or individual stage sections to be raised and lowered according to pre-programmed positions, speeds, and timing sequences. The movements can be triggered by cues or synchronized with the timecode of music, lighting, and visual content, creating impressive effects for performer entrances, spatial transformations, and scene transitions. When multiple stage lifts are integrated into a single system, directors can create multi-level stage configurations, ramps, performance platforms, and coordinated sequential movements . Beyond visual effects, stage lifts can also reduce scene-change time, minimize manual labor, and improve movement accuracy and consistency between performances. For safe operation, the system should be equipped with position sensors, travel limits, load monitoring, emergency stop controls, and mechanisms for detecting discrepancies between lifting points . The allowable load must be determined based on the actual working height and lifting stroke and should account for performers, stage props, surface finishes, and all accessories moving with the platform. Conclusion The Chain Lift 60R Series programmable stage lift meets the requirements for precise and flexible vertical movement in modern stage systems. With a lifting stroke of up to 5,000 mm and a working height ranging from 1,000 to 5,500 mm , the system can be used to raise performers, stage props, musical instruments, or create multi-level stage structures according to the show's programmed sequence. For actual project implementation, the appropriate configuration should be selected based on the required load capacity, lifting stroke, and synchronization requirements of each project. The system should also incorporate comprehensive position monitoring, travel-limit protection, load monitoring, and emergency-stop functions to ensure stable, accurate, and safe operation.

Control functions and system synchronization The Vector Console transforms the EXE Vario hoist into a programmable, cue-based stage motion system. Technicians set target positions, speeds, acceleration, and timing, and link multiple axes to create synchronized movement. Cues can be run individually, chained together, or triggered in sequence. Timecode support allows cues to follow the show's timeline, ensuring movement aligns perfectly with audio, lighting, and video. PosiStageNet (PSN) is an open network protocol for real-time 3D positional data transmission. As the Vector outputs the position of each axis via PSN, a media server can receive these coordinates, map them to virtual objects, and update content in sync with the actual movement. 4. Connection Signal Flow Device Connected Device / System EXE Vario Hoist Kinesys Elevation / Control Network Kinesys Elevation / Control Network Vector Console / Vector Software Vector Console / Vector Software Media Server (e.g., Disguise) Note: The output/input of PSN data or specialized drivers depends on the software version, network configuration, and the specific media server used. Always verify the configuration against current technical documentation before show deployment. Conclusion The EXE Vario 500 kg D8 is a variable-speed chain hoist designed for professional stage lifting and motion systems that require not only load-lifting capabilities but also precise control over position, speed, and movement sequencing. With a 500 kg working load, a lifting speed of 20 m/min, a 2.2 kW motor, dual DC brakes, and compatibility with control systems like the Vector Console, the unit supports motion configurations programmed via cues and timecode. During actual deployment, the appropriate hoist configuration, chain, chain bag, control system, and network setup must be selected based on the specific requirements of the production. Parameters regarding load, safety factors, electrical configuration, and software integration capabilities must also be verified against the manufacturer's current technical documentation before the equipment is put into operation.

Synchronized Hoist
Technical Specifications Item Specification Product model RH-1000S4 Equipment type D8 electric chain hoist Safe working load 1,000 kg Control type Direct Control Operating voltage AC 400 V / 50 Hz, 3-phase Motor 0.75 kW × 4P (4-pole motor) Lifting speed at 50 Hz 4 m/min Lifting speed at 60 Hz 4.8 m/min Number of chain falls 1 Load chain Grade 80; 7.1 × 20.2 mm; compliant with EN 818-7 Duty classification FEM 2m / ISO M5 Duty cycle ED 40% Starts per hour 240 Enclosure rating IP54 Hoist weight 47 kg, excluding load chain Power cable 3 m long, red 4-pin CEE connector Operating noise level 75 dB(A), measured at a distance of 1 m Applicable standards / guidelines BGV D8 / IGVW SQP2:2018 Structural and Safety Features Component / Function Technical Description Heavy-duty DC brake A spring-applied DC electromagnetic brake automatically holds the load in the event of power loss or a malfunction. The design is intended for low maintenance requirements, with only minor periodic adjustments required. Overload-protection friction clutch The friction clutch helps protect the transmission mechanism when the load exceeds the permitted threshold, reducing the risk of damage to the hoist and rigging system. IP54 enclosure The enclosure provides limited protection against dust and protection against water splashes from various directions, making it suitable for stage environments when operated within the manufacturer's specified conditions. Standard-compliant load chain Only Grade 80, 7.1 × 20.2 mm chain compliant with EN 818-7 should be used. The chain link dimensions, pitch, and sprocket geometry must be precisely compatible. Load hook The rigging hook can swivel and is equipped with a safety latch. It should be inspected before each use in accordance with the inspection procedures established by the operating organization. Suitable Applications Rigging for concerts, events, and touring productions. Lifting and suspending lighting equipment, line-array speaker systems, and stage structures. Theatrical props, scenic elements, and television production stages. Permanent installations in theaters and performance venues. Overhead lifting applications where the D8 classification and control configuration are appropriate for the approved rigging plan. Direct Control and Multi-Hoist Operation The RH-1000S4 receives power and direct forward/reverse commands through a compatible control system using a 4-pin CEE connector. When multiple hoists are connected to a direct-control hoist control panel, the operator can issue lifting or lowering commands to a group of hoists. However, receiving the same command does not necessarily mean that the hoists will maintain precisely synchronized positions. Differences in load, voltage, chain elongation, and brake characteristics can result in variations in travel distance. If the application requires multiple lifting points to maintain the same elevation or perform controlled positional movements, a suitable solution incorporating travel measurement/encoders, load monitoring, and a control system designed for synchronized movement is required. Reference Dimensions Dimension Value Shown in Manufacturer's Drawing Overall height shown in drawing 650 mm Horizontal body length 247 mm + 221 mm Hoist body height 156 mm Upper hook area dimensions 105 mm + 185 mm Hook dimensions 23 mm / 30 mm / 33 mm, depending on the position shown in the drawing Accessories and Compatibility Compatible with direct-control hoist cables and control panels using a red 4-pin CEE connector. Accessories specified by KUPO include the RH-1000-1 W flight case and CH-52B protective cover . For low-voltage centralized control, the manufacturer recommends selecting the RH-1000LV instead of the RH-1000S4. Compared with the RH-1000S8 , the RH-1000S4 operates at a lower speed of 4 m/min, making it suitable for applications where standard lifting speed and easier movement control are preferred. Important Notes on the D8 Classification Important: The D8 classification refers to the equipment classification, while its use must comply with the applicable rigging plan, safety procedures, secondary safety requirements, and regulations in force at the venue. The D8 classification should not be interpreted as automatically permitting scenic movement above people. The selection, installation, operation, inspection, and maintenance of the hoist must be carried out by competent and appropriately qualified personnel . Conclusion The KUPO RH-1000S4 is a suitable choice for rigging systems requiring a 1,000 kg D8 electric chain hoist with Direct Control and a standard lifting speed of 4 m/min . Designed with stage environments in mind, the hoist combines a heavy-duty DC brake, overload-protection friction clutch, Grade 80 load chain, and FEM 2m / ISO M5 duty classification to support the lifting and suspension of stage equipment, structures, and scenic elements when implemented according to an appropriate technical rigging plan. However, hoist selection and operation should not be based solely on the 1,000 kg rated load or D8 classification . The operating organization should assess the actual load, rigging configuration, control system, installation conditions, secondary safety requirements, and applicable safety regulations in full. For synchronized movement across multiple lifting points or precise positional control, an appropriate control and monitoring solution should be used rather than simply grouping multiple hoists through a Direct Control configuration.
