NCCCO - National Commission for the Certification of Crane Operators Pick and Carry Operations 1

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

Fully extended and set on pads

Answer

Partially extended for added stability

Answer

Extended only on the load side

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

It is the same, since the load line tension does not change

Answer

It is higher, because momentum assists the lift

Answer

It doubles when the crane is on rubber tires

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

As high as necessary to clear all overhead obstacles

Answer

At a height equal to half the boom length

Answer

At the height specified on the load chart for maximum radius

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

The swing brake, applied lightly throughout travel

Answer

The boom hoist, to rapidly reposition the boom

Answer

The anti-two-block warning device

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

Sound the horn three times and proceed immediately

Answer

Extend the boom to maximum length to check for clearance

Answer

Confirm that the swing lock is engaged to prevent load movement

Question 6

During a pick and carry operation on a rubber-tired crane, why is it generally NOT recommended to engage the swing lock while traveling?

Accepted Answer

It can transmit sudden lateral forces directly to the crane structure if the crane tilts or shifts on uneven ground

Answer

It reduces the effectiveness of the braking system

Answer

It prevents the anti-two-block device from functioning

Answer

It is only prohibited when the boom is over the front
