Abstract:
1. A cable pulling system for pulling cable through a cable tray, comprising: a plurality of elongate brackets, each of the brackets having downward extending portions at opposite ends adapted for physically coupling the bracket to the cable tray, wherein each of the brackets comprises a central portion having a length dimensioned and configured for extending across an open top of the cable tray; a jet loop supported by the plurality of brackets, the jet loop being rotatable and adapted for having the cable attached thereto, the cable being pulled through the tray by rotation of the jet loop; an eyelet bolt attached to each of the brackets, the jet loop passing through the eyes of the eyelet bolts, wherein the eyelet bolts are fastened to the central portion of each of the brackets so that the eyes of the eyelet bolts extend down into the tray, whereby the jet loop is suspended from the brackets; a plurality of clamp plates corresponding in number to the downward extending portions of the brackets, each of the downward extending portions having one of the clamp plates corresponding therewith, the clamp plates and the downward extending portions of the brackets having opposing faces having complementary indentations formed therein adapted for receiving wires forming sides of the cable tray therein; a plurality of fasteners clamping the clamp plates and the downward extending portion of said brackets together on opposite sides of the cable tray; a horizontal roller extending between the downward extending portions of one of said brackets, the roller having a hollow central shaft; and a bolt extending through the hollow shaft and through opposing pairs of said clamp plates and the downward extending portion of said brackets, the bolt being selectively fastened thereto, the horizontal roller easing transition of the cable through elevation changes in the cable tray.
