Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of your rough terrain crane. These procedures are designed to help identify potential issues before they lead to equipment failure or accidents.
Wire Rope Inspection Procedure
- Position boom at comfortable inspection height
- Wear gloves to protect hands from wire rope strands
- Visually inspect entire length for kinks, broken strands, or bird caging
- Check for rust, corrosion, or lack of lubrication
- Verify proper spooling on drum with no overlap or crossing
- Inspect rope attachments at both ends
Outrigger Deployment Check
- Ensure area is clear and ground is suitable for deployment
- Extend beams fully and verify locking mechanisms engage
- Lower outrigger legs smoothly with no jerking motion
- Check for hydraulic leaks during extension
- Verify outrigger pads are properly positioned
- Confirm crane is level using level indicators
Load Moment Indicator (LMI) Test
- Power up the system and verify displays are functioning
- Check that the correct crane configuration is selected
- Verify outrigger position setting matches actual setup
- Test alarm functions with a small, known load
- Verify readouts match expected values for test load
- Test anti-two-block function if integrated with LMI
Control Function Testing
- Start engine and let hydraulic oil warm to operating temperature
- Test each control function individually at slow speed
- Check for smooth operation with no unexpected jerking
- Verify boom raise/lower, extend/retract functionality
- Test swing mechanism for smooth rotation in both directions
- Confirm hoist up/down operates correctly with no abnormal sounds
