The Adaptive Electric Wire-Rewinding System solves one of stage engineering's most persistent challenges: managing power and signal cables for moving stage equipment. As hoists, lifts, and flying systems traverse the grid, traditional cable management creates clutter, trip hazards, and maintenance headaches. Our rewinding system elegantly eliminates these problems.
Intelligent Adaptive Winding
The core innovation is adaptive speed matching — the rewinder automatically synchronizes its winding speed with the connected hoist or lift, maintaining optimal cable tension at all times. This prevents both cable slack (which creates tangling) and excessive tension (which damages conductors). The control system detects movement commands and responds instantly, ensuring cables are always properly managed regardless of hoist speed or direction changes.
Integrated Power and Signal Management
The system carries both power (9 x 2.5mm² conductors) and data (2 DMX512 signal lines) in a single managed cable, eliminating the need for separate power and signal cable management systems. This integration is particularly valuable for moving lights and intelligent fixtures that require both power and DMX control at their mounting positions.
Clean Architectural Installation
The ceiling-mounted design requires only a 170mm diameter opening for the cable exit, presenting a minimal visual footprint in architecturally sensitive spaces. The compact housing (D424 x W540 x H550mm) fits within standard ceiling voids and grid structures. At just 47kg, the unit is manageable for two-person installation teams without special lifting equipment.
Advanced Safety Features
The system supports both override descent commands (for emergency manual lowering) and synchronized descent (coordinated movement with the hoist). The 12-meter travel range accommodates typical theater grid heights and venue ceiling configurations. The 15kg maximum cable tension is carefully calibrated to protect cable integrity while ensuring reliable retraction.
Ideal Applications
This rewinding system is essential for: theater fly systems with moving LX bars, TV studio lighting grids with repositionable fixtures, multipurpose halls with reconfigurable ceiling elements, convention centers with movable rigging points, and cruise ship theaters where space efficiency is critical.
As an experienced stage machinery manufacturer in China, BRD Technology provides full system design consultation to ensure proper integration with your existing hoist and control infrastructure.
Often specified as a self-rewinding hoist, servo stage winch or intelligent winch, this system manages rope as it pays out and rewinds, which removes slack-rope faults on multi-point flying. It is used where a venue needs an intelligent hoist that can be programmed and monitored from the stage machinery control system.
