NCCCO Lift Planning and Critical Lift Procedures 3

Question 1

When planning a lift near electrical power lines, what is the minimum default clearance distance required by OSHA for lines up to 350 kV?

Accepted Answer

15 feet

Answer

OSHA requires a minimum 15-foot clearance from power lines up to 350 kV when no table value is available.

Question 2

During lift planning, the 'rated capacity' of a crane refers to:

Accepted Answer

The load limit established by the manufacturer for specific configurations

Answer

Rated capacity is the manufacturer-established maximum load for a specific boom length, angle, and radius configuration.

Question 3

A 'tandem lift' requires special planning because:

Accepted Answer

Two or more cranes share the load, making load distribution critical

Answer

Tandem lifts involve multiple cranes sharing a load, so precise coordination and load distribution calculations are essential to prevent overloading either crane.

Question 4

What document must be developed and approved before performing a critical lift?

Accepted Answer

A written lift plan reviewed by a qualified person

Answer

Critical lifts require a written lift plan that must be reviewed and approved by a qualified person before the lift begins.

Question 5

Which condition would most likely classify a routine lift as a 'critical lift'?

Accepted Answer

The lift exceeds 75% of the crane's rated capacity

Answer

A lift is typically classified as critical when it exceeds 75% of the crane's rated capacity, requiring enhanced planning and oversight.
