Among the many structural components of the stage electric hoist, the design of the brake device and clutch stands out particularly and can be called the "dual safety lines" for ensuring stage safety.
The brake device adopts an external explicit design with a prominent and intuitive position, which not only facilitates operators to quickly identify potential hazards during daily inspections, but also enables direct positioning, rapid disassembly and maintenance when faults occur. This greatly shortens the downtime for maintenance and avoids delays to the rehearsal or formal performance schedule caused by equipment malfunctions.
The clutch is innovatively installed directly outside the gearbox, breaking the design limitation of the built-in clutch in traditional hoists. In case of faults such as jamming or incomplete separation, maintenance can be completed by performing targeted inspection and repair on the external clutch without disassembling the entire gearbox, which significantly reduces the difficulty and cost of maintenance. In addition, the gearbox equipped on the device adopts lifelong grease lubrication technology and uses high-adaptability special lubricating grease. It can maintain a stable lubrication effect under the working condition of long-term high-frequency start-stop operations without regular disassembly for oil replacement. This not only reduces the maintenance workload, but also avoids the risk of stage environmental pollution caused by oil stains during the oil replacement process, further meeting the environmental protection requirements of stage scenarios.
