Whenever a rope reaches a sheave on which it is wound with a deflection angle, it is also
forced to twist around its axis before reaching the sheave bottom. This mainly arises when the
distance between winch and sheave is too short. Generally, the maximum angle for special
hoisting ropes should never exceed 1.5° ÷ 2° to avoid distortion of the steel wire rope.
However, considering the peculiar characteristics of our range of rope constructions, the
table below gives the maximum recommended, risky, and unacceptable fleet angles.
