ABSTRACT:
A drive for machines for winding cables or similar elongate objects on and off a flanged drum having a center hole includes at least two columns and a pair of support elements that are supported by a respective one of the columns for vertical powered movements therealong. The support elements are joined to one another by a transverse telescopically extensible crossbeam. A pair of bearing bosses are each carried by respective ones of the support elements and are adapted to being inserted into the center hole of the cable drum such that, upon movement of the support elements (and hence the bearing bosses), the drum will be raised above a foundation upon which it normally rests. At least one resilient, yieldable wheel is pivotally connected to one terminal end of a link so as to be capable of resting against the flange. The link is, in turn pivotally coupled to one of the support elements. A guy structure extends between and is operatively connected to the other terminal end of the link and a stationary position on one of the columns. The link and the guy structure have predetermined lengths such that, when the bearing bosses are introduced into the center hole of the cable drum while it rests on the foundation, the wheel is set a defined distance from the drum flange. Thus, when the drum is raised, the flange will be pressed against the wheel such that preselected driven pressure is exerted thereby against the drum flange. The drum is thus reliably rotated upon rotation of the wheel so as to wind cable on and off the drum.
