Five hydraulic rod pusher/puller models cover a wide range of underground crossing requirements: Including installing new utility lines and replacing existing lines.
These compact machines install new underground utilities by pushing steel rods under roadways, etc. and pulling the required pipe or cable back; and they can replace existing lines by pulling pipe splitting and/or bursting tools through the old pipe and pulling a new pipe into the same space. The new pipe can be the same size or larger than the old pipe.
One person can operate these machines. It has two hydraulic cylinders controlled by one valve, which puts the operator in control of the machine and his/her own safety. The cylinders actuate the patented jaw system that grips the push rods. Because the centerlines of the cylinders producing the force and the rods being pushed are on the same plane, the machine introduces no bending forces. A pressure gauge gives the operator constant feedback on the amount of force being used. Standard products include hydraulic rod pusher/puller machines (pipe pushers), portable hydraulic power units and related equipment.
