  • System for laying communications cable especially adapted for aerially stringing fiber optic cable and adapted for interchangeable use with conventional cable
    Patent number: 4852856
    Abstract: A system for laying communications cable that includes a reel of fiber optic cable mounting on a vehicle. The cable is unreeled and looped around a capstan wheel. An hydraulic motor used to rotate the capstan wheel may over spin when pulling cable off the capstan wheel or free spin when rewinding cable back onto the reel. The hydraulic motor output is torque limited when tension in the fiber optic cable between the reel and the capstan wheel exceeds a predetermined amount, thereby reducing the tension in the fiber optic cable. The hydraulic motor may also be disabled to permit free spinning of the capstan wheel when conventional cable is being laid. The system also includes reel brakes to prevent undesired pay-out of cable, with the magnitude of the braking force depending upon whether the associated reel carries delicate fiber optic cable or relatively strong conventional cable.
