Abstract: The invention provides a pipe jack for pulling a pipe lengthwise through the ground without the necessity of excavating the ground to create a trench first, the jack including a number of hydraulic rams coupled to a set of jaws, and the jaws being hydraulically displaceable to clamp a pipe disposed between them.BACKGROUND OF THE INVENTIONThis invention relates to pipe jacks, which are known devices for use in hauling pipes, cables and the like through the ground. By disconnecting a length of pipe or like at both ends, and then pulling the pipe lengthwise, the expense and labour of creating a trench, that is removing earth from above the pipe, can be avoided. In cases where the pipe runs below a surfaced road, pavement or the like, additional substantial costs in resurfacing are avoided. A new pipe may be installed in similar manner for example by attaching the same to the trailing end of the old pipe being removed, or by threading the new pipe into the orifice created by withdrawing the old pipe.
