What to do if CM LODESTAR NH Chain Hoists hook moves in wrong direction?
- J
  Jesse KellyAug 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.

  Julie CoxAug 31, 2025
  If your CM Chain Hoists is operating sluggishly, consider these potential causes: * The load may be excessive. Reduce loading to the capacity limit of hoist as indicated on the identification plate. * Low voltage can hinder performance. Correct the low voltage condition. * Phase failure or unbalanced current in the phases (three phase unit only). Check for electrical continuity and repair or replace defective part. * The brake could be dragging. Check the brake adjustment.

- K
  Kendra GutierrezSep 2, 2025
  If the hook on your CM Chain Hoists fails to stop at either or both ends of travel, check the following: * The limit switches may not be opening circuits. Check switch connections, electrical continuity, and mechanical operation. Check the switch adjustment. * The limit switch shaft may not be rotating. Check for damaged limit switch gears. * The traveling nuts may not be moving along the shaft due to a loose guide plate or damaged threads. Tighten guide plate screws and replace any damaged parts.

  Melanie CraigSep 7, 2025
  If your CM Chain Hoists will not operate at slow speed in either direction, consider these possibilities: * There may be an open circuit due to an open or shorted motor winding, a loose or broken wire, or a speed selecting contactor stuck in the opposite speed mode. Replace the motor, repair the wire, and/or replace the speed selecting contactor. * There could be a phase failure. Check for electrical continuity and repair or replace defective part.

  Laura FoxSep 9, 2025
  If your CM Chain Hoists will not operate at fast speed in either direction, check the following: * There may be an open circuit. Open or shorted motor winding, loose or broken wire in circuit, speed selecting contactor stuck in opposite speed mode. Replace motor, repair wire and/or replace speed selecting contactor. * There could be an open speed selecting circuit due to a winding issue, loose connection, mechanical binding, or control station contact problems. Replace the speed selector, repair the connection, replace the contactor or control station. * There could be a phase failure. Check for electrical continuity and repair or replace defective part.
