摘要： Apparatus for replacing underground pipe is described, including a resistance plate from which a pair of hydraulic cylinders extend perpendicularly parallel with each other. The cylinders operate cyclically with a pulling bridge having a cable gripper to provide a sequence of pulling strokes to a cable pulling a mole. The mole pulls a replacement pipe behind it through the old pipe, which has been burst, slit, or expanded by the mole. The resistance plate is provided with a slot, and the cylinders are positioned to allow the mole to be pulled substantially completely into the apparatus. A holding bridge is releasably mounted spanning the slot in the reaction plate to position a second cable gripper for holding the cable on the return stroke of the pulling bridge. The holding bridge may be removed at the end of the pulling operation to accommodate the mole. A robust, lightweight construction is described.

摘要： A pipe parting mole (40) including a length of cable (70) that is engageable to the mole (40) and a cable pulling device engagement system generally includes a reaction plate (96) and an annulus type member (124) for removably engaging the cable pulling device therewithin. A cable pulling frame (84) may be used to facilitate the removal of the cable (70) from a relatively small hole (32) that is created at the pulling end (36) of the pipe (14).
