NCCCO Crane Safety and Pre-Operation Inspection 4

Question 1

During a pre-operation inspection, you notice the load line has a visible kink. What is the correct action?

Accepted Answer

Remove the kinked section from service immediately

Answer

A kinked wire rope must be removed from service immediately because kinking permanently damages the rope's structure and significantly reduces its load-bearing capacity.

Question 2

What does the term 'rated capacity' mean on a crane load chart?

Accepted Answer

The maximum load the crane can lift under specified conditions

Answer

Rated capacity is the maximum load a crane is designed to handle under specific conditions of boom length, radius, and configuration as shown in the load chart.

Question 3

A crane operator notices the boom hoist limit switch is not functioning. Which action is appropriate?

Accepted Answer

Tag out the crane and report it out of service

Answer

A non-functioning boom hoist limit switch is a critical safety defect requiring the crane to be taken out of service until repaired.

Question 4

When inspecting hydraulic outrigger pads, what is the primary concern?

Accepted Answer

Adequate size and condition to distribute load on the ground surface

Answer

Outrigger pads must be large enough and in good condition to distribute the crane's load over a sufficient area to prevent sinking or tipping.

Question 5

According to OSHA 1926.1417, which of the following defects requires a crane to be immediately taken out of service?

Accepted Answer

A load hook with a latch that does not fully close
