AI Technical Summary
Technical Problem
The existing electric lifting devices have a large radial dimension of rope pulley, which affects the ease of use.
Method used
The gear shaft is positioned on the inner side of the pulley circumferentially, and the pulley can only rotate in the forward direction through a ratchet structure and an anti-reverse structure. Combined with a dust cover design, this prevents reverse rotation and wear.
Benefits of technology
This effectively reduces the radial dimension of the electric lift, improves ease of use, reduces safety hazards, and ensures operational safety and stability.
