Lifting technicians summarize the troubleshooting method for electric chain hoists

2018-10-10
The failure of the electric Chain Hoist is a problem frequently encountered by crane operators. There are many reasons for the failure. Xiongfeng lifting technicians introduce the troubleshooting method for the Electric Chain Hoist and the reasons for the use of the crane:


1. During the operation of the crane, the fuse of the control circuit is burned and the operator must check and replace the correct fuse;

2. If the construction personnel incorrectly connects the power line phase, it will cause the phase protection function to start. Therefore, it cannot be operated. In such a case, the crane operator can reverse the power lines of the two phases and eliminate the fault.

3. The electric wire or power cable of the control circuit is broken or not connected during the installation of the Electric Hoist. The operator must check carefully and repair or replace the broken and poorly-contacted wires.

4. During the operation of the crane, the electric hoist with no fuse switch tripping or the fuse blown can not run. At this time, the operator must check whether the current demand meets the requirements, replace the appropriate fuse or restart the fuseless switch in time.
