Study Notes

Working on Site

Effective risk mitigation and safety are priorities in the lifting equipment industry.
High professional standards are expected by stakeholders, customers, and employers.
Competence in technical abilities is essential, along with service standard management.
Successful completion of training leads to LEEA Diploma in Mobile Cranes and potentially a TEAM Card.
TEAM Card holders are recognized as 'competent persons' in lifting operations, providing assurance to end-users.

Operator and Cab Controls

Conduct thorough checks of the cab and chassis cab:
- Maintain an uncluttered and tidy cab.
- Ensure the operator's seat is in good condition and functions correctly.
- Inspect for loose wires or panels.
- Confirm that the Rated Capacity Limiter (RCL) is fully functional.
- Verify crane-specific load charts are available in the cab.
- Ensure there are no obstructions in the operator's view.
- Check that safety glass is used and not modified.
- All control functions must be clearly marked and operational.
- Test the swing brake and tilt cab mechanism for proper function.
- Ensure lights, windscreen wipers, and climate controls operate correctly.

Crane Controls

Verify that all control functions and switches are clearly marked and perform as intended.
To validate RCL operation:
- Confirm rated capacity charts match the crane model.
- Measure closed boom length against the capacity chart.
- Test boom settings and measure capacity displayed on the RCL against the chart.
- Physically measure radius and attach known loads to verify RCL accuracy.

Load Monitoring Indicator

Ensure the Load Monitoring Indicator (remote bar graph) is secure and functioning correctly.

Swing (Slew) Gear Mechanism

Examine internal swing gear through visual and audible inspections.
For external swing drives, check:
- Gear teeth wear and drive motor noise.
- Condition of bolts and existence of excessive movement under load.
Conduct periodic inspections for wire rope safety:
- Confirm rope integrity and assess for factors needing immediate or timed withdrawal.

Inspection of Wire Ropes

Systematic and logical examination of wire ropes and attachments is crucial:
- Check rope drum anchorage and detachable terminations for broken wires.
- Inspect ropes at entry points into terminations, sheaves, hook blocks, and on the rope drum.
- Look for abrasion damage, heat exposure, and spooling or crossover issues.
- Evaluate slippage in ferrules.

Inspection Frequency

Periodic inspections are mandated every 12 months or every 6 months for people-carrying machines.
Examiner findings should be accurately recorded on a report format.

Severity Rating and Compliance

Examine data for:
- Number of broken wires.
- Diameter decrease, corrosion, and overall damage.
Combine individual severity ratings into a percentage for the assessment table.
Determine if the rope remains safe for continued service, potentially adjusting the next examination period based on condition.
