  • Publication number: 20080069643
    Abstract: Presented is an underground cable laying apparatus that leaves virtually no visible scar in the turf under which a linear member may be installed. The apparatus utilizes a turf slicing apparatus comprising at least one slicing wheel operably coupled to a mounting yoke. The apparatus has a linear member guide formed by the mounting yoke. A guide cover is adapted to cover a length of the linear member guide and movable between a first position to cover a length of the linear member guide and a second position to open the length of the linear member guide. At least one turf wheel may be connected to the guide cover and adapted to substantially close the slit created by the turf slicing apparatus.

  • Publication number: 20070253781
    Abstract: 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.
