    • 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.The known devices have comprised a screw operated vice for gripping the pipe, and attached to a hydraulic ram which is contracted to haul the vice and hence the pipe towards the stationary end of the ram.SUMMARY OF THE INVENTIONThe objects of the present invention are to provide an improved pipe jack.In accordance with the present invention, a pipe jack comprises a number of fluid powered rams which extend between a fixed head and a movable head, the latter being provided with a plurality of jaws, each of said jaws being hydraulically displaceable to clamp a pipe or like disposed between the jaws.Preferably the jaws are levers of the first order, being pivoted to the head, having a serrated or like gripping surface at a free end, and lying against hydraulically activated pistons housed in the head at their other ends: three equi-angularly spaced jaws being preferred.The jaws may be spring returned from the hydraulically closed position by hairpin springs interposed between the head and the jaws, or for example by extensions of the lever ends coupled to tension springs.Preferably also the movable head comprises a centreing device comprising a series of radially movable plungers which may be equi-spaced about the head and alternated with the jaws, and the plungers are associated with means for displacing all of them to similar radial positions together, so that pipes or like of different diameters can be accommodated in a single apparatus and to ensure that the jaws grip the pipe at equi-spaced positions, as a result of the centreing action of the plungers. The plunger displacing means are preferably manually operated.Alternatively a more single centreing device may be provided comprising equi-spaced radially directed screws.
