Crane Inspections Daily inspections include: –Operating mechanisms to ensure proper working order –Air or hydraulic systems for leaks –Hoist chains/ropes for wear, twisting, distortion Periodic inspections: –Deformed, cracked, or corroded components –Loose bolts or rivets –Wear on brakes, chain drive sprocket

Hoisting Safety Avoid sudden acceleration or deceleration Watch for obstructions Never leave controls with load suspended Do not use cranes for side pulls Never lower the load below the point where less than two full wraps of rope remain on the hoisting drum

22 Copyright  Business & Legal Reports, Inc. Sling Angles Ratings based on a vertical hang –Slings hung >= 5° angle from vertical Slings used at angles should be checked for capacity

23 Copyright  Business & Legal Reports, Inc. Assume 1,000 lb. load lifted with 2 slings You would need to provide slings that… Slings vertical: 500 lb. Cap. each Slings 45° from vertical: 707 lb. Cap. each Slings 60° from vertical: 1,000 lb. Cap. each Slings 75° from vertical: 1,930 lb. each Angle Examples 1,000 lb.
