NCCCO Crane Safety and Pre-Operation Inspection 2

Question 1

Under OSHA 29 CFR 1926.1412, crane inspections are divided into which two categories?

Accepted Answer

Frequent and periodic inspections

Answer

OSHA 29 CFR 1926.1412 divides crane inspections into frequent inspections (daily/monthly depending on use) and periodic inspections (annually or as required by the manufacturer).

Question 2

During a pre-operation inspection, an operator discovers that the crane's load line anti-two-block device is inoperative. What action should the operator take?

Accepted Answer

The crane must be taken out of service immediately until the anti-two-block device is repaired

Answer

An inoperative anti-two-block device is an immediate removal-from-service deficiency. The crane must not be operated until the device is functional, per OSHA 29 CFR 1926.1416.

Question 3

What is the purpose of checking hydraulic hose and fitting condition during a crane pre-shift inspection?

Accepted Answer

To identify leaks, chafing, abrasion, or damage that could result in sudden hydraulic failure during operation

Answer

Pre-shift hydraulic inspection identifies hoses and fittings that show signs of leakage, wear, or damage that could lead to sudden hydraulic pressure loss, causing uncontrolled movement or load drop.

Question 4

According to OSHA standards, which of the following conditions requires a crane to be immediately removed from service?

Accepted Answer

Any visible crack in a load-bearing structural member

Answer

Any visible crack in a load-bearing structural member is an immediate removal-from-service condition. Structural cracks compromise the member's load-carrying capacity and can propagate rapidly under load.

Question 5

What should an operator do if a crane's rated capacity placard (load chart) is missing or illegible?

Accepted Answer

Remove the crane from service until the original manufacturer-issued load chart is obtained and installed

Answer

OSHA requires the load chart to be in the cab and legible at all times. If it is missing or unreadable, the crane must be taken out of service until the manufacturer provides a replacement.
