Can someone talk about the working principle and structure of the winch

The working principle of the winch is to convert electrical energy into mechanical energy through the motor, that is, the rotor of the motor rotates and outputs, and then drives the drum to rotate after decelerated by the triangular belt, shaft and gear. The drum winds the steel wire rope and passes through the pulley block to make the crane hook lift or drop the load Q, convert the mechanical energy into mechanical work, and complete the vertical transportation and loading and unloading of the load. The electric winch mechanism is composed of motor, coupling, brake, gearbox and drum, which are installed on the frame together.

The electric winch is required to have good speed regulation performance under the condition of large lifting height, large loading and unloading capacity and busy work, especially when the empty hook can drop rapidly. For materials that are installed in place or sensitive, they should be able to drop at a inching speed.

The winch includes JK fast winch and JM slow winch, which can only be used on the ground. It is powered by electric motor, driven by elastic coupling, three-stage closed gear reducer, tooth coupling, and electromagnetic braking.

The product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient use and transfer. It is widely used in lifting or horizontal dragging of materials in buildings, water conservancy projects, forestry, mines, wharfs, etc. It can also be used as a supporting equipment for modern electric control automatic operation lines.
