ABSTRACT OF THE DISCLOSURE A novel compound drum hoist is provided herein. It includes (a) a first or outer cable-spooling drum rotatably and drivingly mounted on a first shaft; (b) a second or inner cable-spooling drum nested within the first drum, and rotatably and drivingly mounted on a second shaft disposed at an angle of 90°+30°, but preferably at a right angle to the first shaft; (c) means for rotating the inner drum while keeping the outer drum stationary, thereby to spool faired cable onto the inner drum; and (d) means for substantially simultaneously rotating the outer drum 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.
