Study Notes

Assessment Criteria for Crane Examination

Examination assesses defects impacting crane strength or functionality.
Important components for assessment include:
- Limiting and indicating devices' accuracy within manufacturer's tolerance.
- Adjustments and alignment as per manufacturer specifications.
- Bearing play, backlash, brake performance should meet manufacturer standards.
- Corrosion, cracks, distortion, and damage must not affect strength or functionality.
- Fluid levels and rope condition also assessed according to manufacturer tolerances.

Competence in Professional Development (CPD)

Joint responsibility between competent person and employer to maintain CPD records.
Records must detail how CPD is achieved.
Three methods of CPD:
- Active: Participation in training courses, seminars, workshops, ensuring up-to-date knowledge.
- Reflective: Engaging with articles, case studies, and journals to recognize personal learning growth.
- Self-Directed: Independent research and reading to improve understanding of relevant information.

Safety Features of Mobile Cranes

Positive swing locks are mandatory for mobile telescoping cranes to prevent boom swinging during transport.
Essential for safe operation, especially in pick-and-carry scenarios.

Central Rotary Distributor Functionality

Allows cranes to rotate 360° with secure fastenings and leak-free hydraulic connections.
Ensures all crane actions function normally even when the cab is rotated.
Examine hydraulic hoses and locking systems for proper operation.

Boom Furniture and Functionality

Includes boom length/angle sensors, cable reeling drums, limit switches, and dynamometers.
Proper attachments are crucial for the effectiveness of rated capacity indicators and limiters.

Cable Reeling Drum Accuracy

Proper cable layout on the drum is vital for accurate length readings during crane operation.
Affects anti-two block signal transmission and overall operational safety.

Fly Jibs vs. Luffing Jibs

Fly jibs are fixed during lifting; main boom adjusts.
Luffing jibs move the main boom, which stays at a fixed length and angle.
Proper stowage of jib attachment pins is important when not in use.

Magnetic Rope Testing (MRT)

MRT assesses wire rope integrity by detecting breaks or corrosion through passing it across a magnet.
Produces a "birth certificate" baseline for wire ropes, enabling monitoring of deterioration over time.
Essential for high integrity cranes, particularly in offshore applications, ensuring safety and reliability.
