Abstract
A cable conveying apparatus and method installs a cable in conduit by the application of a pushing force generated by a drive assembly. The speed of the cable and the speed of the drive assembly are monitored wherein the drive assembly is shut off when the drive assembly and cable speeds exceed a predetermined difference. The cable conveying apparatus includes a blower, and a missile attached to the lead end of the cable, wherein the missile sealably and slideably engages the conduit such that the blower and missile combine to generate a pull force on the cable which cooperates with the pushing force of the drive assembly so as to install the cable in the conduit. The cable conveying apparatus also includes a high speed cable shut off system, and a low speed cable shut off system. The drive assembly includes two opposed continuous chains each including a plurality of cable engaging pads, and each driven by a hydraulic motor. A hydraulic cylinder preferably holds the drive chains at a spaced apart distance.
