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.

What to do if CM Lodestar B Chain Hoists hook raises but will not lower?
- R
  robert40Aug 27, 2025
  If your CM Chain Hoists hook raises but will not lower, consider these potential issues: * There may be an open lowering circuit due to a winding issue, loose connection, or open control station or lower limit switch contacts. Check electrical continuity and repair or replace the defective part. Check operation of limit switch. * For single-phase units, the motor reversing switch may not be operating.

  usnyderAug 29, 2025
  If your CM Chain Hoists hook lowers but refuses to raise, here's what to investigate: * The load may be excessive. Reduce loading to the capacity limit of hoist as indicated on the identification plate. * There may be an open hoisting circuit due to a winding issue, loose connection, or open control station or upper limit switch contacts. Check electrical continuity and repair or replace the defective part. Check operation of limit switch. * For three-phase units, there could be a phase failure. Check for electrical continuity and repair or replace defective part.

Why CM Chain Hoists operates sluggishly?
- I
  isabella25Aug 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.

What causes CM Lodestar B Chain Hoists hook to fail to stop at ends of travel?
- K
  Kimberly HartSep 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.

What to do if CM Chain Hoists will not operate at slow speed?
- Y
  youngkatieSep 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.

What to do if CM Lodestar B will not operate at fast speed?
- A
  andrea75Sep 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.
