Bridge Crane Visual Inspections (Daily)
Follow this procedure for the inspection of proper operation, worn parts & damage.
1. Manual Controls - Check all manual controls for proper operation.
2. Limit Switch - 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. Then test with increasing speeds up to maximum. The switch should shut the hoist off before the bottom block contacts the rod or weight type limit switch at the upper extreme. 1 1/2 Wraps of rope should remain on the drum at the shut-off point at the lowest extreme. do not r
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. Refer to manual for adjustment or repairs.
4. Unusual Conditions - Excessive noise, oil leaks, etc. should be investigated.
CAUTION!!!! DO NOT OPERATE THE HOIST IF ABOVE INSPECTION INDICATES THAT MAINTENANCE IS NEEDED. CONTACT MAINTENANCE FOR REPAIRS.
