Key Inspection Procedures
Follow these detailed procedures to ensure a thorough inspection of critical rough terrain crane components. These procedures align with ASME B30.5 standards and OSHA requirements.
Wire Rope Inspection Method
- Clean rope sections of dirt and grease for proper examination
- Check for broken wires (6 or more broken wires in one lay or 3 in one strand in one lay)
- Look for severe kinking, crushing, or bird-caging
- Examine for reduction in rope diameter (more than 5% reduction)
- Inspect for heat damage or electrical contact
- Check end connections (damaged, improperly applied)
- Examine for corrosion (external or internal)
- Document findings with specific measurements and locations
Outrigger Inspection Sequence
- Visually inspect outrigger beams for cracks, bends, or damage
- Check outrigger cylinders for leaks, scoring, or rod damage
- Verify all pins and keepers are in place and secure
- Examine outrigger pads for flatness, cracks, or excessive wear
- Test outrigger controls for proper function and response
- Inspect hydraulic hoses for leaks, wear, or improper routing
- Test outrigger interlocks or indicator systems if equipped
- Verify outriggers extend and retract smoothly without binding
Safety Device Testing
- Test anti-two-block device by activating all movements that could cause two-blocking
- Verify load moment indicator with known weights or by comparing to load chart at various radii
- Check boom angle indicator against physical measurement with inclinometer
- Test level indicators against known level reference
- Verify outrigger interlocks prevent unsafe operations
- Test all alarms for proper function and audibility
- Verify emergency stop buttons instantly stop all crane functions
- Document all safety device tests with specific outcomes
Hydraulic System Check
- Check hydraulic fluid level when all cylinders are retracted
- Examine hydraulic fluid condition for color, smell, and contamination
- Inspect all hoses for leaks, rubbing, weathering, or kinks
- Check all hydraulic cylinders for leaks at seals and fittings
- Observe function speed and response of all hydraulic systems
- Listen for unusual noises during hydraulic operations
- Check for proper pressures at gauge readings
- Inspect hydraulic filters indicator for replacement needs
