Study Notes
Outrigger Jacks and Beams
- Ensure outrigger beams are level; misalignment may signal cracked welds, worn sections, or missing pads.
- Inspect hoses, connections, and pipes for cracks, deformations, or leaks.
- Check beam interiors for hydraulic oil presence to detect leaks; use access holes if available.
- A dry jack ram is essential; oil residue indicates potential seal leakage, worsening over time.
- Observe smooth operations during crane setup and check alignment of locking holes and availability of pins.
- Look for hose and pipe deformation for early signs of damage and operational issues.
Controls and Level Indicators
- Verify that operating controls are in good condition and clearly labeled.
Preparation for a Thorough Examination
- Position the crane in a safe area for examination.
- Conduct inspections in well-lit conditions; use portable lighting if necessary.
- The crane must be clean to avoid concealed defects, with cleaning not the examiner's responsibility.
- Ensure safe access and egress with approved structures like walkways, platforms, or scaffolding.
- Confirm that personnel using portable access equipment are trained and competent, with agreed-upon PPE requirements.
Identification and Documentation
- Identification and rated capacity markings must be clear and verified against crane records.
- Key documents include test certificates, legal conformity declarations, manufacturer manuals, and prior examination reports.
History and Records
- Examine for recorded defects, malfunctions, and past modifications or alterations.
- Review previous examination reports, in-service inspections, and maintenance logs.
- Record findings in a structured report format.
Severity Ratings and Assessment
- Ratings for the examination record include broken wires, diameter decrease, corrosion, and overall damage.
- Sum individual severity ratings to create a total combined severity percentage.
- Optionally, use descriptive severity terms instead of percentages based on an equivalence table provided.
- The examiner must decide the rope's safety for continued service; if approved, consideration may be given to reducing the time before the next examination due to current deterioration levels.
