Electric Motors For Crane Applications

The application of motors on cranes has the following main aspects:

1. Lifting and lowering goods: The motor transmits power to the lifting mechanism of the crane through the transmission device, driving the movement of goods in the vertical direction. By controlling the speed and working time of the motor, the lifting and lowering operations of goods can be realized, providing the crane with the important ability to lift goods.

2. Mobile crane: Some large cranes, such as bridge cranes, tower cranes, etc., need to be moved at the work site. The motor drives the crane's mobile devices, such as tires, crawlers, etc., allowing it to move freely on the job site. The output power of the motor can help the crane overcome resistance and achieve precise movement.

3. Rotation and slewing: The crane needs to be able to perform slew and slew in the horizontal direction in order to accurately position the goods to the required location. The motor drives the rotating mechanism of the crane through the transmission device, allowing the crane to rotate in the horizontal direction. The speed and control of the motor enable precise positioning and rotation operations of the crane.

4. Auxiliary equipment drive: In addition to the above main applications, motors can also be used to drive some crane auxiliary equipment, such as lights, fans, hydraulic pumps, etc. The operation of these equipment is very important for the work and operation of the crane, and the motor can provide the necessary power support.
