If your R&M Chain Hoist isn't lifting or lowering the load, there are several potential causes:
* The emergency stop button might be activated. If so, deactivate it.
* A fuse may have blown, requiring replacement.
* The motor's thermal protection could be activated; in this case, allow the motor to cool down.
* The pendant plug pin might be pushed out; reinstall the plug pin.
* Contactor terminal screws could be loose; tighten them.
* The mainline switch might be off; turn it on.

If your R&M Chain Hoist isn't lifting the load, it could be due to several reasons:
* An overload condition: Reduce the load.
* A worn or incorrectly adjusted slip clutch: Replace worn parts or readjust the slip clutch torque.
* The brake not releasing: Check the brake coil resistance, air gap setting (adjust if needed), and rectifier output voltage.

Why does the load drift more than 4 inches during an emergency stop with my R&M LM?

Brian ReevesAug 28, 2025
If the load drifts more than 4 inches [100mm] during an emergency stop with your R&M Chain Hoists, it's likely that the brake lining is worn. Adjust the brake slipping clutch and replace the slipping clutch components if necessary.
