Question 648 Deck General

70% to pass

Which statement(s) is/are TRUE regarding the operation of a crane?

A The crane jib is raised and lowered by the hoisting winch.
B The load is handled by the hoisting winch and cargo block.
C The cargo block is raised and lowered by the luffing winch.
D All the above
AI Explanation

The correct answer is B) The load is handled by the hoisting winch and cargo block. This is correct because the hoisting winch is responsible for raising and lowering the cargo block, which in turn controls the movement of the load. The jib (or boom) of the crane is typically raised and lowered by a separate luffing winch, not the hoisting winch. Additionally, the cargo block, not the luffing winch, is the component that directly engages with the load being lifted. The other answer choices are incorrect because A) the jib is raised and lowered by the luffing winch, not the hoisting winch, and C) the cargo block is raised and lowered by the hoisting winch, not the luffing winch.
