Abstract
A conduit cable feeding sheave assembly is disclosed having a frame structure, an axle assembly disposed within the frame structure, and a sheave wheel disposed about the axle assembly. In one embodiment, the sheave wheel is fabricated of a self-lubricating, durable polymeric material. A slotted, tubular arm affixed to the frame extends along a line substantially tangential to the wheel. The arm has an exterior diameter sized to fit within a conventional conduit pipe, preferably having a diameter ranging from 2 to 10 inches. In one preferred embodiment, the tubular arm has at least one locking mechanism for temporarily securing the conduit sheave assembly within the conduit pipe. One disclosed locking mechanism is a threaded screw that extends from the interior of the tubular arm to engage the conduit.
