Why CM Lodestar L hook stopping point varies?
If the stopping point of your CM Chain Hoists hook varies, here are some potential causes: * The limit switch may not be holding its adjustment. * The brake may not be holding. Check the brake adjustment. * The limit switch shaft may be binding. Check the limit switch bearing for proper seating.
What to do if CM Lodestar L hook lowers when hoisting control is operated?
If the hook on your CM Chain Hoists lowers when the hoisting control is operated, it could be due to: * Phase failure (three phase unit only). Check for electrical continuity and repair or replace defective part. * Phase reversal (three phase unit only).
What causes CM Lodestar L hook to fail to stop at ends of travel?
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.
Why CM Lodestar L Chain Hoists operates sluggishly?
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 to do if CM Lodestar L hook lowers but will not raise?
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.
What to do if CM Lodestar L hook raises but will not lower?
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.
What to do if CM Chain Hoists hook does not stop promptly?
If the hook on your CM Chain Hoists fails to stop promptly, the following could be the reasons: * The brake may be slipping. Check the brake adjustment. * The load may be excessive. Reduce loading to the capacity limit of hoist as indicated on the identification plate.
