Bi parting stage curtain system is a mechanical device used to control the symmetrical opening and closing of the main curtain in theaters or auditoriums. Typically driven by an electric motor, it transmits power to the curtain via steel cables or synchronous belts in conjunction with pulleys and tracks, enabling the curtain to move smoothly and in sync to both sides. This system is generally equipped with control devices (such as push-button panels or PLCs) that enable manual or automatic operation. It features smooth operation, low noise, and high safety and reliability, and is widely used in various types of performance venues.
Product Structure
Bi parting stage curtain system is composed of components such as triangular truss, reducer, servo motor, aluminum alloy track, corner pulley group, tightening adjustment wheel, nylon front carriage, nylon curtain hook, mechanical limit, servo control system, etc.
Product Features
The driving part adopts a servo drive system, with soft start and soft stop, precise position control. The corner pulley block, front car, and hook are all made of high-quality cast wheels and high-quality nylon, ensuring durability and no noise during opening and operation. The track adopts high-quality aluminum alloy technology, greatly reducing the weight of the equipment, facilitating installation, greatly reducing on-site production time, and achieving good operating results.

Selection Criteria
Load and Span
For medium and light loads, large spans, priority is given to steel wire ropes; for heavy loads and high-precision positioning, priority is given to gear racks.
01
Synchronization and Silence
For elegant opening and closing, choose steel wire ropes; for strong bearing capacity and rigidity, choose gear racks.
02
Environment and Maintenance
For dusty / humid environments, choose chains or gear racks; for low maintenance and lubrication-free requirements, choose steel wire ropes.
03
Safety Compliance
Must meet fire resistance (such as GB 8624), limit position and forced disconnection requirements.
