A hand-operated hoist works primarily by turning the handle, which activates the internal ratchet-and-pawl mechanism and gear transmission system.

It utilizes chains or steel ropes to enable the lifting, towing, or lowering of heavy loads. The main four core components are as follows:

· Handles and directional mechanism: The primary operating components that provide power when the board is moved; the direction can be switched between “up” and “down” via a toggle lever.

· Braking System: Comprising ratchets, pawls, friction pads, and other components, this system ensures that heavy loads can be securely positioned and prevents them from falling.

· Transmission gear set: amplifies the force applied to the handle, driving the hoisting chain wheel or wire rope drum to rotate.

· Enclosure and load-bearing components: protect internal components. Hoisting chains or steel ropes are used for lifting through hooks and other mechanisms.
