NCCCO Lift Planning and Critical Lift Procedures 5

Question 1

According to ASME B30.5, a lift over a public roadway typically requires:

Accepted Answer

Permits, coordination with authorities, and often a written lift plan

Answer

Lifts over public roadways require appropriate permits, coordination with local authorities, and typically a documented lift plan for traffic management and safety.

Question 2

When must a lift plan be revised during an ongoing operation?

Accepted Answer

When conditions change significantly, such as a weather change or unexpected ground conditions

Answer

Lift plans must be updated whenever site conditions change significantly enough to affect the safety assumptions on which the original plan was based.

Question 3

The function of outrigger float pads (cribbing) during lift planning is to:

Accepted Answer

Distribute the outrigger load over a larger area to reduce ground bearing pressure

Answer

Cribbing or outrigger pads spread the concentrated outrigger load over a greater surface area, reducing pressure on the ground and preventing sinking.

Question 4

Which factor is NOT typically required in a critical lift plan?

Accepted Answer

The crane operator's personal fitness level

Answer

While operator qualifications and certifications matter, personal fitness level is not a standard element documented in a critical lift plan.

Question 5

When a crane is operating on a slope, how does the incline affect the lift plan?

Accepted Answer

The effective radius increases on the downhill side, reducing the rated capacity for lifts in that direction

Answer

A crane on a slope experiences an increased effective radius on the downhill side, which reduces the rated capacity for lifts made toward the low side.
