发明名称 Cable Injector And Puller For Pipe Bursting
摘要 A cable handling apparatus and method for using the same in pipe bursting applications. In one mode, the apparatus injects a cable through at least one gripping element and into a pipe. Protrusions open the at least one gripping element to allow the cable to feed through freely. The cable is fed by a powered injection pulley. In another mode, the apparatus pulls a pipe burster, attached to the cable, through a length of pipe. In a preferred embodiment comprising two cable grippers, each cable gripper grips the cable in a first position, pulls the cable until the cable gripper is a second position, then returns to the first position. The apparatus is adapted such that a first cable gripper is in the first position when a second gripper is in the second position. Alternatively, the cable grippers may move from the first position to the second position in tandem. The cable handling apparatus further comprises a reel. The reel is used to store excess cable and impart additional force on the cable.
