Through the analysis of the common problems and treatment of the wire rope electric hoist, the maintenance personnel can know where to start the inspection and improve the inspection efficiency when handling the fault. In addition, also can provide the operator with a method for handling the problem on site.
Electric hoist is frozen.
In winter construction, especially after snow, the fault-free motor still cannot be started, the reason is that the brake ring is frozen. If it is forced to start, it will be easy to burn the motor.
The solution is to open the motor cover and use a crowbar to shake the motor so that it can rotate freely.
After shutdown, the sliding distance during braking exceeds the specified requirements.
When the wire rope electric hoist is applied for a long time, the brake ring wears too much, so that the brake spring pressure reduce and the braking force reduce.
The solution is to adjust the brake bolt or replace the brake ring.
The rope can be only up, but can not be down.
The reason is that the travel limiter is damaged and the travel limiter needs to be replaced.
