Question 538 Deck General

70% to pass

If an electric cargo winch is being used to lift a draft of cargo and the engine room loses all power, which will occur?

A The load will fall rapidly to the deck unless the foot brake is engaged.
B An electromagnetic brake will hold the load where it is suspended.
C A pawl, forced by a spring mechanism, will engage the teeth of the bull gear and hold the load.
D The load will slowly lower to the deck under control of the drag of the winch motor.
AI Explanation

The correct answer is B) An electromagnetic brake will hold the load where it is suspended. When the engine room loses power, the electric cargo winch will no longer have power to operate. However, the winch is typically equipped with an electromagnetic brake that will automatically engage and hold the load in place when power is lost. This ensures the load does not fall rapidly to the deck, which would be unsafe. The other options are incorrect because A) the foot brake would not be engaged without power, C) the pawl and spring mechanism require power to operate, and D) the winch motor would not be able to provide controlled lowering without power.
