Crane Inspections come in two forms -- frequent and periodic. Prior to conducting crane inspections, it is important to have a background on what type of inspection is about to be performed and what specific items are going to be checked. Both have different objectives:
Frequent Inspection Checklist
- Cranes are checked for any maladjustments which may hamper its optimal performance.
- Check for any impairment or leakage in lines, tanks, valves, drain pumps, and other air or hydraulic systems.
- Inspect for any deformation or cracks in the hook. Also, note for any unusual sound. These are included in both daily and monthly inspection. A certification record must be maintained with the inspector's signature and date during monthly inspection.
- Check the hoist chains along with its end connections for any distortion.
- Thoroughly check for any excessive wear of components.
- Check whether the wire rope reeving system is working in accordance to manufacturer’s recommendations.
- Check brakes and emergency switches whether they are operational.
Periodic Inspection Checklist
Additional inspection steps that are typically performed on an annual basis:
- Check for any deformation, cracks or corrosion of components.
- Search for loose bolts or rivets; cracked or worn sheaves and drums; worn, cracked or distorted pins, shafts, gears, bearings, rollers, locking and clamping devices.
- Look if there is an excessive wear on brake and clutch system parts, linings, pawls, and ratchets.
- Check load, wind, and other indicator inaccuracy.
- Check for any fault or unsafe power plants including exhaust leakages and emergency shutdown feature.
- Inspect for worn out chain drive sprockets and excessive chain stretch.
- Inspect electrical apparatus for any pitting or any other impairment of controller contactors, limit switches and push-button stations.
