What must be consulted before performing a pick and carry operation with a mobile crane?
Answer: The crane manufacturer's load chart and operational instructions must be consulted to confirm that pick and carry is permitted for the specific crane model and to determine the load limits and travel requirements
Not all cranes are rated for pick and carry. The manufacturer's documentation must confirm it is permitted, and specific load charts for traveling operations (which are lower than static lift charts) must be used.
What is the recommended boom position relative to the direction of travel when a lattice boom crane is traveling with a suspended load?
Answer: The boom should be positioned in line with the direction of travel (pointing forward or backward) to minimize lateral bending on the boom structure
For lattice boom cranes, the boom should be aligned with the direction of travel to ensure dynamic forces from travel go along the boom's longitudinal axis (which it is designed for) rather than creating lateral loads that could damage the boom.
What is the maximum recommended travel speed for a crane traveling with a suspended load?
Answer: The speed must be limited to what is specified in the manufacturer's load chart for traveling operations, typically very slow (often under 2 mph)
Pick and carry operations must be performed at the speed specified by the crane manufacturer for traveling with loads — typically very slow speeds (under 2 mph for many cranes) to minimize dynamic forces.
When traveling with a load on an unpaved surface, what ground condition concern is most critical?
Answer: Soft spots, holes, ruts, or cross-slopes that can cause the crane to tilt or an outrigger to drop into a void, potentially causing upset
Soft ground, holes, ruts, and slopes encountered during travel can dynamically tilt the crane or cause wheel or track to sink suddenly, changing the load moment unexpectedly and potentially causing crane overturn.
What is the role of a tag line during a pick and carry operation?
Answer: Tag lines are held by ground personnel to control load swing, prevent the load from rotating, and guide the load around obstacles during travel
Tag lines held by ground workers allow them to control load movement during travel — preventing swinging, managing rotation, and guiding the load safely around site obstacles during pick and carry operations.
Before beginning a pick and carry operation, what is the primary inspection that should be performed on the travel path?
Answer: A walking survey of the entire travel path by a qualified person to identify soft spots, slopes, grade changes, overhead obstructions, underground hazards, and surface obstacles before the crane begins moving with the load
The entire travel path must be physically walked and inspected — overhead clearances, surface conditions, slopes, and underground hazards must be identified and addressed before the crane moves with any load.
