How did the crane parts stop working?
Selecting high-quality parts and fitting them together can form a crane. The importance of parts in the crane can be seen, and electric hoists are part of it. But if the electric hoist, which is a key component, fails to operate, how will the crane operate normally?
Once you encounter a similar problem, first check if its power fuse has been blown out. Even if one of them is broken, the electric hoist cannot be turned. Another is that the voltage of the power grid is too low. Since the dynamic torque of the equipment is proportional to the square of the voltage, the acceleration torque cannot overcome the load torque, so it will not run normally. ,
It may also be caused by a short-to-phase, ground or open circuit fault of the stator windings. The electric hoist's terminal box needs to be opened for inspection, but it must be remembered that the motor cannot be inspected during a short circuit to avoid danger. After the cause of the failure is found, targeted measures can be taken to improve it.
