When performing a pick and carry operation over soft or uneven ground, the operator should:
Answer: Reduce the load and travel speed, and use mats or cribbing if needed
Soft or uneven ground increases tipping risk; reducing load and speed, and using mats or cribbing, improves stability.
The term 'tipping load' in pick and carry operations refers to:
Answer: The load at which the crane will begin to tip, used as the basis for rated capacity
Tipping load is the load at which the crane actually begins to tip, and rated capacities are a percentage of this value.
During pick and carry operations, what effect does extending the boom length have on crane stability?
Answer: It decreases stability by increasing the load radius and boom weight
Extending boom length increases the load radius and adds boom weight at a greater moment arm, both of which reduce stability.
Which of the following conditions would require the operator to STOP a pick and carry move immediately?
Answer: Any of the above
Any of these conditions—load swing, capacity warning, or spotter signal—requires immediate cessation of travel to assess and correct the situation.
For a pick and carry crane rated at 40 tons stationary, the travel capacity is typically:
Answer: Less than the stationary capacity
Travel (pick and carry) capacity is always less than stationary capacity due to the additional dynamic forces introduced by movement.
What should an operator do when approaching a railroad crossing during a pick and carry operation?
Answer: Stop before the crossing and check for rail traffic before proceeding
Operators must stop before railroad crossings, check for oncoming trains, and obtain permission if required before crossing.
When a load chart specifies 'side' capacity for a pick and carry crane, this means capacity with the load positioned:
Answer: Directly over either side of the crane perpendicular to travel direction
Side capacity applies when the load is directly to the side of the crane, perpendicular to the direction of travel, as defined by the manufacturer.
