The new machine is supplied with a hydraulic power unit delivering 100 Bar at 80 litres per minute or 200 Bar at 50 litres per minute resulting in a maximum pushing force of 11 tonnes. With an insertion speed of up to 4 metres per minute, the machine will typically install 300 to 400 metres in one operation. By fitting insert shells, it will accommodate pipe down to 350mm diameter.
The company’s standard range includes a 125mm pneumatic machine plus 180mm, 315mm, 350mm and 500mm hydraulic models. Each machine can accommodate various smaller pipe diameters by fitting insert shells. Manual pushing machines are also available for inserting service pipes with diameters between 20mm and 40mm.
Pipe pushing machines are used as a safe and cost effective alternative to the use of winches – or excavators and slings – for inserting pipe.
Steve Vick International pushing machines work on the principle of grasping the pipe in a set of jaws, thrusting it forward and holding it in that position whilst the jaws return to the start position ready to push the pipe again. Pneumatic and hydraulic machines are operated by a simple control lever and none requires specialist operator skills.
The pushing action can be reversed should an obstruction be encountered allowing the operator to withdraw the pipe a short way and try to insert it again. If the obstruction persists the problem can be investigated by excavating without having to remove the remainder of the
The new 630 pushing machine is available to hire or purchase from Steve Vick International Ltd.
