Bridge Crane Visual Inspections (Daily)

This daily pre-use checklist verifies a bridge crane’s safe operation by testing manual controls, limit switches, and hoist stopping performance under load. Inspectors also look for cable/chain damage, excessive noise, and leaks, and must halt operation and report issues if any defects are found.

1. Manual Controls - Check all manual controls for proper operation.

2. Limit Switch & Wire Rope/Chain Inspection - Check the upper and lower limit switch by running the hook without load and at the slowest speed obtainable, to the maximum up and maximum down positions while inspecting cable/chain for frays, twists, stretch or kink. The switch should shut the hoist off before the bottom block contacts the rod or weight type limit switch at the upper extreme. A minimum of 1 1/2 Wraps of rope should remain on the drum at the shut off point, lowest extreme.

3. Hook Drift - With a load the hook should stop promptly when the push button is released. Hook drift of more than 2 inches indicates that either one or both of the hoist brakes is malfunctioning.

4. Unusual Conditions - Excessive noise, oil leaks, etc. should be investigated.

Notes

CAUTION!!!! DO NOT OPERATE THE HOIST IF ABOVE INSPECTION INDICATES THAT MAINTENANCE IS NEEDED. CONTACT A SUPERVISOR OR MAINTENANCE FOR REPAIRS.
