Hook Overhead Crane Parts
Hook overhead crane mainly consists of five core components: metal structure, hoisting mechanism, operating mechanism, electrical system, and safety device.
The trolley travel mechanism is on both ends of the bridge. It can drive the overhead crane along the factory or dock along the rails. This allows the overhead crane to adjust its working position over a wide range. The trolley moves along the rails, which allows flexible positioning of the lifting mechanism. It is responsible for the vertical lifting and lowering of heavy loads. This ensures smooth and safe lifting thanks to a precise transmission system and a braking device. The electrical system provides power to each mechanism of the overhead crane. It also precisely controls its operation, including motors, controllers, limit switches, etc., to ensure safe and accurate operation.
