ABSTRACT:
An apparatus for pulling an electric cable or wire between two locations such as along the length of a pipeline is described including an engine mounted in the box of a truck and having a pinch wheel operatively connected thereto. A torque balanced pulling rope is extended around the pinch wheel and passes through spaced-apart sheaves mounted on the pipeline. The free end of the rope is connected to the electric cable which is to be pulled along the length of the pipeline. The rope passes from the pinch wheel to an automatic rope tender mounted on a trailer positioned rearwardly of the truck. The automatic rope tender is operated at a slightly greater grade than the sheave wheel and deposits or drops the rope into a storage container. The automatic rope tender includes means for lifting the storage container from the ground to enable the container to be moved from one location to another.
