What should a service truck crane operator do before every shift to ensure safe operations?
Answer: Perform a pre-shift inspection of the crane, truck, rigging, and all safety devices per the manufacturer's checklist
A thorough pre-shift inspection covering the crane structure, hydraulic system, rigging, safety devices, and carrier vehicle must be completed before each work shift.
How does the mounting position of a service truck crane relative to the truck's axles affect lifting capacity?
Answer: Crane position affects how load is distributed between axles, influencing stability and the load chart capacities
The crane's mounting position on the truck chassis affects load distribution to the axles and the stability baseline, which directly influences the rated capacities in the load chart for different swing positions.
What is the correct action if the hydraulic fluid becomes very hot during extended service crane operations?
Answer: Stop crane operations and allow the system to cool before continuing; check for the cause of overheating
Overheated hydraulic fluid degrades rapidly, causing seal damage and reduced system performance; operations must stop, the cause of overheating investigated, and the system allowed to cool before resuming.
What hazard is created when a service truck crane is operated with the outriggers not fully extended per the load chart configuration?
Answer: The actual stability base is narrower than assumed in the load chart, reducing the real safety margin below minimum requirements
Operating with outriggers at less than the load chart's specified extension uses a narrower stability base than the chart assumes, effectively invalidating the chart and reducing the actual tipping safety margin below required minimums.
What does 'two-blocking' mean in service truck crane operations and why is it critical to prevent?
Answer: The hook block rises until it contacts the boom tip sheave, causing rope failure or damage to the rigging system
Two-blocking occurs when the hook block is raised until it contacts the boom tip sheave assembly, jamming the system and generating extreme forces that can break the wire rope, damage the boom, or drop the load.
What is the purpose of an annual inspection for a service truck crane and who must perform it?
Answer: Annual inspection is a comprehensive examination of all crane components by a qualified inspector to verify continued fitness for service
Annual inspections are mandatory comprehensive examinations performed by a qualified inspector covering structural, mechanical, hydraulic, and safety components to verify the crane remains safe for continued use.
