Chain electric hoists are widely used in multiple fields due to their superior efficiency and convenience, providing customers with the working principle of chain electric hoists for reference:

　　1. The chain electric hoist lifting mechanism is a mechanism used for vertical lifting of materials, and is the most important and basic mechanism of cranes. As long as there is a lifting mechanism, it can be called a lifting equipment.

　　2. By manipulating the control system of the chain electric hoist, the driving device converts the power energy input into mechanical energy, and transmits the force and motion speed to the retrieval device. The retrieval device then connects the transported material with the crane and completes the material handling task through individual or combined movements of the working mechanism.

　　3. The movable metal structure connects various components into a whole and carries the self weight and lifting weight of the crane.

　　The lifting mechanism, operating mechanism, luffing mechanism, and rotating mechanism of the electric chain hoist are known as the four major mechanisms of the crane. The crane achieves the purpose of transporting materials through the individual movement of a certain mechanism or the combined movement of multiple mechanisms.

　　5. The operating mechanism is a mechanism used to achieve horizontal material handling. Some operating mechanisms are only used to adjust the working position of the crane.

　　6. The luffing mechanism is a mechanism that changes the operating amplitude by changing the length and elevation of the boom.

　　7. The rotating mechanism can cause the boom to rotate around the vertical axis of the crane, allowing the crane to transport materials in the annular space. The luffing mechanism and rotating mechanism are unique working mechanisms for jib cranes.

　　8. The control and operation system of the chain electric hoist includes various manipulators, displays, related components, and circuits, which is the interface that embodies the human-machine safety requirements of the crane.

　　9. Through the electrical and hydraulic systems, the crane driver can control the movement of the crane, ensuring the smooth progress of lifting tasks and preventing accidents.
