ABSTRACT:
A winch 100 is provided for taking up or paying out cable 13 without damaging protrusions 14 spaced along the cable from potentially high compressive forces applied to the cable when it is wound over drum members 16, 18, 20 of each of a pair of drum mechanisms 30A and 30B. The winch is operated so that the cable is pulled over the drum members and wound about the two drum mechanisms as a unit, such that successive cable protrusions are always maintained in successive cable path spaces between the drums of each drum mechanism.
