What is the purpose of checking ground conditions before deploying outriggers on a service truck crane?
Answer: To verify the soil has adequate bearing capacity to support the maximum expected outrigger load without sinking or shifting
Ground bearing capacity must be verified before outrigger deployment to ensure the soil can support the concentrated outrigger loads without settling, which could cause the crane to tip during operations.
What must a service truck crane operator do when working in a traffic area?
Answer: Establish a traffic control plan, use spotters, cones, and appropriate barriers, and ensure all workers wear high-visibility clothing and that the crane's swing radius is protected from vehicle intrusion
Working in traffic areas requires comprehensive traffic control measures including physical barriers, spotters, high-visibility gear, and protection of the crane's swing radius from vehicles and pedestrians.
Why is it essential for a service truck crane operator to know the exact weight of every load before lifting?
Answer: Exact load weight is needed to select the correct load chart column and verify the lift is within rated capacity before committing the load to the hook
Exact load weight is the primary input for load chart consultation; without it, the operator cannot verify whether the planned lift is within the crane's rated capacity for the planned configuration and radius.
What is the purpose of a pre-task safety briefing before beginning a service crane lift?
Answer: A pre-task briefing communicates the lift plan to all involved personnel, assigns roles, identifies hazards, and ensures everyone understands their responsibilities and emergency procedures
Pre-task safety briefings ensure all personnel involved in the lift understand the plan, their specific roles, identified hazards, and emergency procedures, preventing miscommunication and coordination failures.
What crane maintenance must be performed after the crane has been used in a salt spray or coastal environment?
Answer: The crane must be thoroughly washed with fresh water, all exposed metal surfaces inspected for corrosion, and additional lubrication applied to all exposed bearings and pins
Salt accelerates corrosion dramatically; after coastal or salt spray exposure, thorough fresh water washing, corrosion inspection, and application of protective lubricants are required to prevent accelerated deterioration.
What is the correct action if the crane's load indicator shows a reading that seems inconsistent with the actual load being lifted?
Answer: Stop lifting, verify the actual load weight by another method, and have the indicator calibration and sensors inspected before relying on it further
An inconsistent load indicator reading suggests a calibration error, sensor malfunction, or incorrect configuration entry; the crane must not be operated beyond verified limits until the indicator's accuracy is confirmed.
