Typical Construction

While each electric chain hoist may have some slight variations in design/arrangement, all hoists
have same basic elements.
1. Motor - basic drive package.
2. Chain Sprocket - moves the load chain to lift and lower the load
3. Gear case Assembly - couples the motor to the chain sprocket
4. Brake/Torque Limiting Device - to stop and hold the load as well as to help prevent lifting of
excessive loads which may damage the hoist.
5. Frame (Hoist Body) - basic structural components that support the load to be handled.
6. Bottom Block and Load Wheel - includes bottom block and chain sprocket.
7. Load Chain - load chain and end connections for picking up the load.
8. Limit Switch – a device for over-travel protection. (Optional for some hoist configurations)
9. Controls - devices for supplying power to motor and reversing direction of the motor.
The following details the operation/maintenance instructions for each basic element. In Figure
4.1 the basic components inside the frame and the basic kinematics are shown.
