Engine General (Supplementary) USCG Question #1051 (Set 19)

As it pertains to the hoist motion limits associated with an electro-hydraulic cargo- handling pedestal-type deck crane, what statement is true?

Official USCG Answer & Rule Citation

Correct Answer: Option C — When the hoist cable is payed out to a nearly empty drum condition or when the hoist block is raised to a maximum permissible height relative to the boom, the hoist pump shall be stroked to zero and the hoist winch brake set.

Hoist limit switches prevent damage from over-travel or cable depletion. When the hoist block reaches the maximum height or the drum reaches the minimum cable limit, the system automatically strokes the hoist pump to zero and sets the brake, ensuring the crane remains within safe operational parameters.
