Abstract : A hoist is described that includes a winding drum for a load-lift cable mechanism. The drum has two drum sections of slightly different diameter; end portions of the cable are wound in different directions on the drum sections, so that one cable section winds onto a drum section while the other cable section winds off the other drum section. The effect is to provide a very slow net cable motion related to the difference in drum section diameters. The hoist includes a latch mechanism adapted to suspend the load from the boom during certain periods of a load transfer operation. (Author).
