Product Details

The ingenuity in the design of the theater audio equipment hoist is equally noteworthy. The core transmission components of the theater audio equipment hoist adopt a modular gear set design. The tooth surfaces undergo precise carburizing treatment, with a hardness reaching HRC58-62. Combined with specially made wear-resistant bearings, the friction coefficient between components is reduced to below 0.015. This design not only reduces mechanical loss but also buffers the impact force during each start and stop — when the audio equipment completes the movement from a stationary state to rising 0.5 meters within 3 seconds, the elastic deformation of the gear set is controlled within 0.02mm, perfectly meeting the high-frequency operation requirements of "quickly lifting the audio during the intervals of lyrics" in musical performances.

What is more noteworthy is that the design of the modular gear set also endows the equipment with excellent maintenance convenience. When a certain gear is worn, technicians do not need to disassemble the entire transmission system; they only need to replace the corresponding module. The replacement time of a single gear set can be shortened to within 20 minutes, which greatly reduces the risk of the theater audio equipment hoist being out of service for theaters that need to perform consecutive shows. At the same time, a flexible coupling is used to connect the gear set and the drive motor. This structure can further absorb the vibration energy during operation, keeping the audio equipment stable during lifting and lowering, and avoiding additional noise interference caused by mechanical vibration — it should be noted that even a 0.1-decibel noise may destroy the overall auditory balance in symphony performances.
