Abstract
The cable pulling device includes a control unit having a force indicator gauge and a switch and circuit breaker assembly in series in the hot wire to the electric motor which rotates the capstan for cable pulling. Power to the electric motor can thereby be interrupted manually or automatically in the event cable pulling force approaches an overload level where damage could occur to the device, accessories and/or cable. The control unit is detachable from the puller device for location close to the operator during a pull.
