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. The system includes a hydraulic reel drive assembly for rewinding cable with relief valves for disabling the reel drive when cable tension exceeds a predetermined amount. The system further includes fiber optic cable guide chutes adapted to be selectively mounted in conventional guide rollers. The system also includes a blade assembly for preventing overlapping of the cable around the capstan wheel and a peripheral shroud for selectively preventing disengagement of the cable from around the capstan wheel.
