Question 2164 Deck General

The correct answer is B) Using a sheave with an undersized throat. Using a sheave with an undersized throat can cause a wire rope to fail. This is because an undersized sheave will create sharp bends in the wire rope, leading to premature wear and potential breakage. The diameter of the sheave should be large enough to maintain the proper bend radius for the wire rope to avoid excessive stress and wear. The other options are not correct. A) Using a medium graphite grease as a lubricant is generally recommended to maintain the wire rope. C) Operating a winch too slow is unlikely to cause wire rope failure. D) A sheave diameter of 24 times the wire's diameter is a common guideline for proper sheave sizing to prevent wire rope damage.
