YT electric hoist motor overheating reason

First, you should check whether the overloaded electric hoist use, overloading causes the motor to heat, long-term overload will burn motor; the motor is not overloaded, still hot, you should check whether the motor bearing damage; also check the motor is required to work the system to work, which is caused by the heat of the motor One reason, the work should be used in strict accordance with the motor duty. When the motor is running, the brake gap is too small, not fully disengaged, have a great friction, friction and heat, while also representing an increase of additional load, the motor speed decreases, the current becomes large and the heat, and you should stop working, again adjust the brake clearance.
Hoist brake stopping distance decline exceeds the requirements on how to resolve
When long-term application of wire rope electric hoist brake ring wear is too large, the brake spring pressure decreases, the braking force is reduced. Workaround for brake adjustment bolt or replace the brake ring.
Weight rose to the air can no longer start after stopping the reason the investigation
First, check the system voltage is too low or too large fluctuations, in the case of this situation, the only other voltage returns to normal after the start; on the other hand, we should pay attention to the three-phase motor operation phase, you can not start after the shutdown, then you need to check Power phase.
