The possible reasons for the gantry crane to burn the motor are: the crane load is too heavy, the motor bearing is damaged, or the brake is not working properly, or the solenoid is not disconnected during operation, or the electromagnetic coil is not contacted well, which causes power failure and locks the brake drum. .
        Another important reason is the lack of phase, the reason for the lack of phase:
        1. The contacts of the gantry crane contactor are frequently activated and quickly burned. The contact springs and the plastic deformation at the contacts will make the contact position insufficient and cause lack of phase.
  2. If the fuse is too small, it will cause heat to blow and phase loss.
   3. Poor power contact causes phase loss.
  4. The motor's incoming wire contact is not good.
  5. Install a high-sensitivity automatic air switch and thermal overcurrent protector, and install a phase loss control device to avoid it.
        The above is the Crane factory reason why the motor of the gantry crane burned.
