Compact cross shaft type compound drum hoist for spooling extra long lengths of tow cable with segmented fairings

Abstract

A novel compound drum hoist is provided herein. It includes a first or outer cable-spooling drum rotatably and drivingly mounted on a first shaft. A second or inner cable-spooling drum is nested within the first drum, and is rotatably and drivingly mounted on a second shaft disposed at an angle of 90.degree..+-.30.degree., but preferably at a right angle to the first shaft. The inner drum is operable to be rotated while the outer drum is maintained stationary, thereby to spool faired cable onto the inner drum. Substantially simultaneously the outer drum is rotated along with the inner drum, thereby to spool faired cable onto the outer drum. Such hoist is thus suitably adapted to wind long lengths of cable with segmented fairings thereon without any significant risk of crushing the fairings.
