ABSTRACT:
The cable puller employs a conically tapered capstan and self-contained motor both carried on a readily collapsible and portable frame. The puller is adapted for placing inside of a manhole where the capstan is aligned with the duct through which the cable is to be pulled. Several such cable pullers may be operated in concert to pull a theoretically endless fiber optic cable at a controlled speed and without exceeding the tensile strength of the cable. Tension on the cable effects the frictional gripping force between the capstan and the cable looped there around and this gripping force controls the extent to which the cable is permitted to climb up and slip down the conical incline of the capstan to a point where equilibrium is reached. A radio-controlled sensor is provided at each pulling station to signal cable stoppage faults and to respond to faults signaled by other pulling stations by shut down of all stations until the fault is corrected.
