What to do if CM Chain Hoists hook moves in wrong direction?
- S
  sallygarzaAug 25, 2025
  If the hook on your CM Chain Hoists moves in the wrong direction, here are a few things to check: * For single-phase units, wiring connections may be reversed at the control station or terminal board. Compare the connections to the wiring diagram. * Also for single-phase units, the motor reversing switch might fail to effect dynamic braking at the time of reversal. Check the connections to the switch and replace any damaged or faulty capacitor. * For three-phase units, there may be a phase reversal.
