Electric hoist lifting motor common problems

The main source of power for assembling and manufacturing electric hoists is the hoisting motor. Generally, the lifting motor type of CD1 and MD1 wire rope electric hoist is ZD series hoisting motor. The hoisting motor speed is 1380 rpm, the three items are electric, the voltage is 380V, and the frequency is 50 weeks/banknote.

Due to improper operation of the electric hoist during use, it is often encountered that the lift motor does not turn, the electric hoist cannot lift heavy objects, etc. The following describes the common problems and solutions for the electric hoist lift motor:

1. The problem caused by the fault of the hoist electrical appliance, the disconnection of the wire or poor contact. The solution is to overhaul electrical appliances and wiring.

2, excessive overload, the problems brought about, the solution is not allowed to overload the wire rope electric hoist, the hoist motor can run normally.

3. The brake wheel and the rear end cover are rusted and the brake wheel cannot be removed. The solution is to remove the brake wheel and clean the rusted surface.

4. The voltage is 10% lower than the rated voltage. The solution is to use the voltage when it returns to normal.

5. The hoist is used too frequently. The solution should be based on the FC30% work system.

6. The brake clearance is too small. The brake ring is not completely disengaged during operation, which is equivalent to additional load. Re-adjust the gap to solve the problem.
