  • Winch and winch drum
    Patent number: 6435480
    Abstract: Rope-holding characteristics of a winch drum (2) are determined by a staggered array of pyramidal protuberances (12, 14, 17, 19) on its surface. The staggering is such that there is no true circular path round the drum within the array, and a rope wound on it in the hoop direction is deflected sinusoidally.
