Abstract
A cable pulling system includes a pickup truck having on-board hydraulic and electrical systems, the hydraulic system including a pump driven by the truck engine, a reservoir tank mounted in the truck cargo bed and associated plumbing. An equipment module is removably mountable on the cargo bed and comprises a pallet which carries a hydraulic control console adapted to be coupled to the hydraulic system, a sump pump removably disposed in a support, a hydraulic winch motor and a take-up reel respectively removably mounted on pivoting supports, a reel of hydraulic conduit having one end thereof coupled to the hydraulic system and the other end adapted to be coupled to the sump pump, and an extension reel of hydraulic conduit for coupling the winch motor or the sump pump to the hydraulic system. The winch motor and take-up reel are mounted on a bumper support for use. A tension controller is supported in use on a tray which can be mounted on the take-up reel storage support after the reel has been removed therefrom. The tension controller is coupled to the electrical system and to the hydraulic motor for controlling the tension applied to the cable being pulled.
