Electric hoist fault treatment
After starting, the motor does not rotate and heavy objects cannot be lifted
Excessive overloading, overloading is not allowed
The voltage is more than 10% lower than the rated voltage, wait for the voltage to return to normal
The electrical appliance is faulty, the wire is disconnected or the contact is poor, and the electrical appliance and the line are repaired.

The wire is too thin, replace the wire
2. The braking is unreliable, and the sliding distance exceeds the specified requirements
Due to the large wear of the brake ring or other reasons, the spring pressure is reduced and the spring pressure is adjusted
The brake ring is in poor contact with the cone surface of the back end cover, remove it for grinding
The brake surface has oil stains, remove it and clean it
The brake ring is loose, replace the brake ring
Pressure spring fatigue, replace the spring
The coupling is not working well or stuck, check its connection part
