Abstract: A mechanized cable puller. By combinig a hydraulic track-mounted excavator with a winding spool the present invention provides underground machinery for pulling underground electrical cable from an underground conduit into an underground cable vault, without requiring the temporary installation of direction-changing pulleys in the cable vault. By using a square bar as part of the underground machinery, the cable can be pulled from any of four different directions, spaced ninety degrees apart, in a three-hundred-and-sixty-degree span.

Abstract: A portable wire puller designed to be operated from a motor vehicle having a hydraulic system. The wire puller utilizes a spool mounted on an axle which is made up of two rods which can be easily connected to and disconnected from one another, so that it is simple and easy to change spools quickly without dismantling the entire apparatus.
