Ø Ensure there are no loose, broken, or damaged parts on the hoist, trolley, bridge, runway, or electric systems.

Ø Check that the wire rope is reeved and seated in the drum grooves properly.

Ø Verify that the bottom block is not twisted (no two lengths of wire rope should touch).

Ø Check that nothing is contacted or close to open power sources and that enclosures are secured.

Ø Ensure there are no wires pulled from strain reliefs or bushings.

Ø Verify that the pushbutton pendant controls are not damaged (check for cracks, torn parts, or missing labels).

After checking out the crane area and conducting a preliminary equipment checkout, the crane operator can inspect the overhead crane itself for any potential malfunctions or safety hazards.

 

DAILY EQUIPMENT SAFETY CHECKOUT (POWERED SYSTEMS):

Ø Ensure that the hoist hook rises when the button is pushed to the “up” position.

Check that the upper limit switch is functioning properly.

Ø Ensure that all other pushbutton controls are operating properly and moving in the right direction.

DAILY EQUIPMENT SAFETY CHECKOUT (HOOKS):

Ø Check that there’s no more that 10 percent wear on any part of the hook.

Ø Check for bending or twisting and cracks.

Ø Check that safety latches are in place and functioning properly.

Ø Ensure that the hook nut (if visible) is tight and locked to hook.

Ø Make sure that the hook rotates freely without grinding.
