ABSTRACT:
A wire pulling apparatus for use in pulling multi-cable wire through a conduit by means of a mechanical or manual pulling force. The conduit is provided at its entrance opening with a bushing including a matrix of grating elements to conform the wire cables to a predetermined pattern. A first reference for the pattern is established by encasing the wire cables at their leading ends in a basket-like device to which is attached a pulling cable leading through the conduit to the pulling element of the apparatus. The grating elements are rotatably inserted through radial holes provided in the bushing and are held in place by bending or threadably attaching nuts at the periphery of the bushing. Generally vertically oriented grating elements define notches for holding generally horizontally oriented grating elements. Furthermore, the bushing is provided with a smooth lip for preventing destructive contact with the wire cables.
