Study Notes
Mobile Crane Safety and Inspections
- The chassis and tyres are crucial for mobile crane safety; they require thorough examination.
- Key components to inspect include:
- Manufacturer’s information plate/label and duty charts
- Tyres, wheels, and axle locking systems
- Crane chassis, crawler tracks, and outrigger jacks with beams
- Braking systems, bolts, pins, and fastenings
- Slew section structure and slew mechanism, with full movement checks
- All piping, hydraulic cylinder fittings, and oil/fluid levels
- Superstructure, jib, fly jib, and all pivoting joints
- Wire ropes, pulleys, sheaves, drum guards, and counterweight systems
- Limiting devices like rated capacity systems and anemometers
Levels of Crane Inspection
-
Pre-use Inspection:
- Conducted by the operator to check for defects or operational safety.
- Involves visual checks and functionality assessment; issues must be reported for further inspection.
- Competence in conducting these checks is essential, relating to training and assessment.
-
Interim Inspection:
- Focuses on critical components that may deteriorate before the next thorough examination.
- Frequency is determined by risk assessments and manufacturer's recommendations.
- Often conducted during planned maintenance or after repairs.
Operator and Cab Controls
- Cab cleanliness and organization must be maintained, ensuring no obstructions.
- Operator’s seat must be functional and in good condition.
- Inspect for loose wires, functional RCL, presence of load charts, and clarity of control markings.
- Ensure safety and operational effectiveness of swing brakes, tilt mechanism (if applicable), lights, and other controls.
- Both windscreen wipers and air conditioning/heating systems should operate correctly.
Crane Controls
- All control functions and switches must be clearly marked and responsive as indicated.
- Regular checks are essential for safe and efficient crane operation.
Cleaning Materials
- Ensure the inspection area is clean to prevent contaminants from obscuring any equipment damage or deterioration.
- Carry basic cleaning supplies, such as rags, wire brushes, and pH neutral cleaning fluids, to clean inspected components as necessary.
- Adhere to chemical safety data sheets and ensure risk assessments include cleaning materials.
Types of Mobile Cranes
Rough Terrain Cranes
- Designed for rough terrain; capable of "lift on rubber" where lifting and traveling occur simultaneously.
- Safety precautions require outriggers to be extended and jacks clear of the ground during function testing to prevent risks from tire failure.
Yard Cranes
- Suitable for yard applications where outriggers may not be practical; can operate on rubber.
- Designed to transport light loads like pumps and motors, providing a stable platform.
Crawler Mounted Telescopic Cranes
- Used for on-site operations; easier to inspect due to hydraulic drive systems.
- Inspection procedures are similar to wheeled cranes, with attention to the undercarriage.
Types of Examination
- Adhere to BS7121-2-1 and BS7121-2-3 standards for thorough crane inspections.
- ISO9927-1 and ISO9927-5 provide similar guidelines for crane examinations.
Preparation for a Thorough Examination
- Safety: Position cranes in safe areas for inspection.
- Lighting: Ensure well-lit inspection environments or use portable lights if necessary.
- Cleanliness: Cranes should be clean to avoid concealing defects; examiners should not be responsible for cleaning.
- Access: Establish safe access for inspection personnel, using suitable platforms and ensuring workers are trained for equipment use.
- Identification: Verify ID and capacity markings against crane records, legal documents, and previous inspection reports.
- History: Review past inspection reports and maintenance logs for recorded defects or alterations.
Load Testing Mobile Cranes
- Consult manufacturers for advice on testing methods and load magnitudes before starting.
- Conduct visual examinations of cranes and testing areas prior to load application.
- Ensure proper rigging based on the manufacturer’s instructions is verified during examinations.
Operator and Cab Controls
- Ensure cab cleanliness, with no clutter, and that operator controls are fully functional.
- Check the operational condition of the operator’s seat, RCL, and crane-specific load charts present in the cab.
- Ensure unobstructed operator views and that safety glass is used without unauthorized modifications.
- Confirm that all switches are clearly marked and operational, including the swing brake and tilt cab mechanism.
- Verify the functionality of lights, windshield wipers, and air conditioning/heating controls.
