What Are the Main Components of Overhead Crane?

Overhead crane is generally composed of main beam, end beam, hoisting mechanism, crane moving mechanism, control room, trolley conductive device (auxiliary slide line), crane main power conductive device (main slide line), etc.

The lifting mechanism is composed of hoisting motor, reducer, drum, brake, etc. The lifting motor is connected with the reducer through the coupling, brake wheel, and the output shaft of the reducer is connected with the winding drum of the steel wire rope. The other end of the steel wire rope is equipped with a hook. When the drum rotates, the hook rises or falls with the winding or releasing of the steel wire rope on the drum.

The heavy objects on the hook moves up and down with the rotation of the drum; the trolley moves left and right in the width direction of the workshop, and moves forward and backward with the cart in the length direction of the workshop.

In this way, it can realize the movement of heavy objects in the perpendicular, horizontal and vertical directions, move the heavy objects to any position in the workshop, and complete the lifting and transportation task.
