ABSTRACT:
A tension take-up system for cable support drums and the like features resilient tension absorbing rollers disposed laterally across the winding surface of the drum. The rollers are partially seated into recessed areas defined longitudinally across the winding surface of the drum and progressively dissipate the tensioning forces generated when high tension cable is pulled into position by using pulling line being wound on the support drum. The recessed areas are capable of accommodating expansion of the rollers when they are depressed as the tensioned pulling line is wound over them. The tension absorbing rollers are made of a highly shock absorbent rubbery material so that, as winding progresses, the resulting compressive forces are dissipated by the progressive deformation of the rollers which causes them to expand within the corresponding recesses on the winding surface of the drum. The system is simple and economical to manufacture, requires little maintenance, has prolonged life and can be adapted for use in a variety of cable laying or winding applications.
