The angle formed between the centerline of a sheave or groove and the direction of travel of the cable or rope coming out of the groove. Maximum allowable fleet angle for counterweight rigging is usually 1 _ deg's.
The angle between the sheave/barrel centerline and the rope at its extreme deflection. The fleet angle should not be less than 1/2°, and should not exceed 2°.
That angle between the rope's position at the extreme end wrap on a drum, and a line drawn perpendicular to the axis of the drum through the center of the nearest fixed sheave. See DRUM and SHEAVE.
