NCCCO Crane Safety and Pre-Operation Inspection

Question 1

Before beginning operations, which document must a crane operator review to confirm the crane's rated capacity for the planned lift?

Accepted Answer

Operator's manual and load chart

Answer

ASME B30.5 and OSHA 1926.1412 require operators to review the load chart and operator's manual before each shift to confirm rated capacities for all configurations.

Question 2

During a pre-operation inspection, you discover a hydraulic hose with a visible bulge and minor weeping. What is the correct action?

Accepted Answer

Tag the crane out of service and notify the supervisor

Answer

A bulging or weeping hydraulic hose is a deficiency that removes the crane from service under ASME B30.5 inspection criteria. Operations must not resume until the hose is replaced.

Question 3

Which of the following is checked during a frequent inspection of a mobile crane under ASME B30.5?

Accepted Answer

All functional operating mechanisms for maladjustment

Answer

ASME B30.5-5.2.2 defines frequent inspections (daily to monthly) as covering all functional operating mechanisms, air/hydraulic systems, hooks, and rope reeving.

Question 4

The anti-two-block device on a crane is designed to prevent:

Accepted Answer

The load block from contacting the boom tip and damaging the wire rope

Answer

An anti-two-block (A2B) device stops hoist motion before the upper load block contacts the boom tip sheave assembly, which would cause rope failure or structural damage.

Question 5

Under OSHA 1926 Subpart CC, how often must a qualified person conduct a shift inspection of a crane?

Accepted Answer

Each shift the equipment is used

Answer

OSHA 1926.1412(d) requires a qualified person to conduct a shift inspection before each shift the crane is used, checking for visible damage, deficiencies, and proper lubrication.
