Overhead Crane Checklist

Check for any loose or missing parts.

Check end stops. End stops prevent the trolley from running off the beam.

Know the location of disconnect switch that will cut the power off only to the hoist or crane. Be sure it is readily accessible and not blocked.

Make sure all control buttons are labeled to indicate their function. Operate each button to make sure it can function properly, release immediately, and do not stick.

Check upper hoist limit switch by slowly raising the block to trip the switch.

Lower the hoist block to activate the lower limit switch if the hoist is so equipped, leaving at least one turn of rope on the take-up drum.

Make sure wire rope is properly seated in its drum and sheave grooves without any slack or overlapping.

Operate the crane or hoist several feet in each direction that it travels. Listen for any unusual noises. Look for any jerky movements.

When moving an A frame hoist, take care to ensure that the wheels on each side stay on the track.

Check all hooks. Hooks should not bu cracked, stretched, bent or twisted. Each hook must have a safety latch that automatically closes the throat of the hook. If the latch is bent, spring is broken, or is otherwise damaged the latch must be repaired before use. Hooks should rotate freely in block assembly without any “grinding” felt or heard coming from the bearings.

Check the block assembly for structural damage or cracks in any components. Sheaves should rotate freely without any grinding felt or heard coming from the bearings. The sheave guard must be unbroken and intact. No part of the sheave guard should be in contact with the wire rope or sheave.

Check the wire rope by lowering the block to the lowest level and looking for the following conditions. If any of these conditions are observed, they should be reported immediately.

1.Reduced diameter of the rope. This may indicate the rope has been stretched, has lost its inner core support, or has worn outside wires.
2.Any number of broken strands of wires.
3.Kinked, crushed, cut, or “bird caged” wiring, or wiring with heat damage.

Check load chain for damage, wear at contact points, cracks or distorted ( bent, twisted, or stretched) links. Inspect all mechanical coupling links to insure linking pins are secure and in good condition. Report unsafe conditions immediately.
