NCCCO Pick and Carry Operations 2

Question 1

What must be consulted before performing a pick and carry operation with a mobile crane?

Accepted 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

Answer

Only the operator's experience and judgment are needed

Answer

Only the site safety officer's approval is required

Answer

Pick and carry is always permitted for loads under 50% of crane capacity

Question 2

What is the recommended boom position relative to the direction of travel when a lattice boom crane is traveling with a suspended load?

Accepted 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

Answer

The boom should be perpendicular (90 degrees) to the direction of travel for maximum stability

Answer

The boom angle should be lowered to 20 degrees for travel to reduce center of gravity height

Answer

Boom position is irrelevant during pick and carry — only load weight matters

Question 3

What is the maximum recommended travel speed for a crane traveling with a suspended load?

Accepted 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)

Answer

25 mph on paved surfaces

Answer

Crane speed is only limited during wind events

Answer

Normal driving speed is acceptable on paved job site roads

Question 4

When traveling with a load on an unpaved surface, what ground condition concern is most critical?

Accepted 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

Answer

Surface dust that may obscure the operator's vision

Answer

The surface must be asphalt or concrete for all pick and carry operations

Answer

The color markings on the ground surface

Question 5

What is the role of a tag line during a pick and carry operation?

Accepted 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

Answer

Tag lines are not used during traveling — they create a tripping hazard

Answer

Tag lines are used to attach the load to the crane boom for stability

Answer

Tag lines replace the need for an outrigger during pick and carry

Question 6

Before beginning a pick and carry operation, what is the primary inspection that should be performed on the travel path?

Accepted 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

Answer

Inspection of the path for other crane operations that may be in the area

Answer

Only the starting point and ending point of travel need to be inspected

Answer

The operator can inspect the path visually from the crane cab before beginning travel
