Study Notes
Truck Mounted Cranes
- Can have limited or 360° operational duties depending on front jack configuration.
- Proper jack placement increases versatility in handling loads.
All-Terrain Cranes
- Designed for various ground conditions; suitable for challenging terrains.
- Steering and travel controls located in the upper cab for efficient maneuvering.
- Dual steering and braking systems need thorough examination for safe operation.
City Cranes
- Feature a shorter, multi-section boom for enhanced urban maneuverability.
- All-wheel steering with a low boom position minimizes overhead obstruction risks.
- Hidden components require dismantling for proper inspection by competent personnel.
Competency in Crane Examinations
- Critical for personnel conducting thorough inspections.
- Required knowledge, skills, and experience vary according to crane complexity and risks involved.
- Ongoing training and independence are essential for effective assessments.
Continuous Professional Development (CPD)
- Promotes continuous skill enhancement and knowledge upgradation.
- Can be integrated into daily work without extensive training sessions.
- Important for staying current with industry standards and practices.
Boom Furniture
- Consists of various components, including:
- Boom length/angle sensors
- Cable reeling drums
- Limit switches
- Dynamometers
- Pressure transducers for load measurement
- Essential for the effective operation of the Rated Capacity Indicator/Limiter.
Cable Reeling Drum
- Powers the angle sensor and other boom equipment.
- Proper cable layering is vital to avoid false readings and ensure accurate performance.
- The drum’s design determines uncoiled cable length and operational accuracy.
Fly Jibs vs. Luffing Jibs
- Fly jibs remain fixed during lifts; the main boom moves.
- Luffing jibs adjust position during lifting while the main boom stays fixed.
- Proper stowage of jib attachment pins is crucial for operational readiness.
Hoist Drums Examination
- Must be securely attached and free of visible damage.
- Hydraulic hoses and connections need to be leak-free and tight.
- Correct layering of wire hoist rope on the drum is essential for operation.
Wire Rope Examination
- Safety relies heavily on thorough inspections by Competent Persons.
- Daily checks by operators are critical for safe machine use.
- Compliance with manufacturer instructions and local regulations is mandatory.
Exceptional Circumstances for Wire Rope Inspection
- Inspections are obligatory after incidents such as accidents or overloads.
- A thorough check is necessary if cranes have been idle for over three months.
Magnetic Rope Testing (MRT)
- Provides insights into the internal condition of wire ropes, enhancing lifting safety.
- Crucial for identifying potential internal flaws that could compromise safety.
