Question 1

During a pick and carry operation, how must the outriggers be positioned before the crane begins to travel?

Accepted Answer

Fully retracted into their travel position

Answer

Outriggers must be fully retracted before the crane travels. Pick and carry operations use the crane's travel ratings, which assume outriggers are stowed; partially extended outriggers create an undefined and dangerous support condition.

Question 2

How does a crane's rated load capacity for pick and carry (traveling with a load) compare to its rated capacity for a stationary lift?

Accepted Answer

It is reduced, because dynamic forces during travel increase stress on the structure

Answer

Travel (pick and carry) ratings are lower than stationary ratings because movement introduces dynamic forces — acceleration, braking, and surface irregularities — that add stress beyond what the static load creates.

Question 3

At what height should the load be carried during a pick and carry operation?

Accepted Answer

As low as practical while still clearing the ground and path obstructions

Answer

Carrying the load as low as practical lowers the crane's combined center of gravity, reducing the risk of tipping. Unnecessarily high loads increase the tipping moment, especially on uneven terrain.

Question 4

What should be used to control load swing and prevent the load from rotating during a pick and carry move?

Accepted Answer

Tag lines, managed by ground personnel walking alongside

Answer

Tag lines allow ground personnel to dampen and guide the load, preventing uncontrolled rotation or swing caused by starting, stopping, or surface irregularities. No mechanical crane control can safely substitute for tag lines in managing a moving suspended load.

Question 5

Before beginning a pick and carry move, what must the operator do regarding the intended travel path?

Accepted Answer

Survey the entire path for surface conditions, grades, obstacles, and overhead hazards

Answer

A pre-travel path survey identifies soft spots, grades, cross-slopes, underground utilities, overhead lines, and obstacles. Discovering a hazard mid-move with a suspended load is far more dangerous than planning a safe route in advance.
