Why is my CM Chain Hoist hook moving in the wrong direction?
If the hook on your CM Chain Hoist moves in the wrong direction, start by checking the wiring connections in the control station or hoist, using the wiring diagram. If you have a single-phase unit, inspect the connections to the cut-out device and replace any damaged components or faulty capacitors. For three-phase units, consult the section on 'Three Phase Hoists'.
What to do if the CM Chain Hoist hook does not stop promptly?
If the hook on your CM Chain Hoist doesn't stop promptly, first check the electric brake, especially the brake disc for wear or glazing, and ensure the brake spring isn't broken. Replace the worn or glazed brake disc or the brake spring if needed. Also, make sure that the load is not excessive, it should be according to the capacity limit indicated on the hoist.
Why does my CM Chain Hoist hook lower but not raise?
If your CM Chain Hoist hook lowers but won't raise, make sure that the load is not excessive. Check for loose connections or broken wires in the hoisting circuit, and ensure the control station contacts are functioning correctly. Repair any wiring issues or replace defective parts. For single-phase units, examine the motor cut-out device and its connections, repairing or replacing as necessary.
Why is my CM Chain Hoist operating sluggishly?
If your CM Chain Hoist operates sluggishly, ensure that the load is not excessive. Check for low voltage and verify that the power supply meets the hoist's requirements. Also, inspect the electric brake to ensure the brake disc moves freely on the brake driver. Replace any warped components. For three-phase units, investigate for phase failure or unbalanced current in the phases.
What to do if CM Chain Hoist hook raises but will not lower?
If the hook on your CM Chain Hoist raises but will not lower, check for open circuits in the lowering circuit due to loose connections or broken wires. Ensure the control station contacts are closing properly. For single-phase units, inspect the motor reversing switch. For three-phase units, investigate for phase reversal or phase failure.
Why does CM Chain Hoist hook fail to stop in either direction?
If the hook on your CM Chain Hoist fails to stop in either direction, check the electric brake and armature for binding, a broken brake spring, a broken first pinion shaft, a worn brake driver, or a worn brake disc. Correct any binding of the armature and replace any broken or worn parts.
How to troubleshoot a CM Chain Hoist when the hook does not respond?
If the hook on your CM Chain Hoist isn't responding, first check for a blown fuse, a tripped circuit breaker, or an open disconnect switch. Replace the fuse, reset the circuit breaker, or close the switch, if necessary. Also, ensure the power supply matches what's on the hoist's identification plate. Check the power supply system to ensure it complies with the requirements. If the issue persists, examine the brake for problems like an open or shorted coil, defective diodes, or a binding brake disc. Check the coil continuity, diodes, and connections. Correct any issues found, such as replacing the coil, repairing connections, or addressing any binding in the brake disc. Reduce the load to the capacity limit indicated on the hoist. Finally, check for electrical continuity and repair or repla...
