The pipe controls allow for the laying of steel pipes with diameters between 406mm and 1.400mm in any subsoil, from cohesive soils and unconsolidated rock, right through to solid rock, in one operation. The horizontal (RS) and the horizontal and vertical (RS-HV) versions can be precisely controlled by means of articulated pipe sections that can be adjusted hydraulically.
Different soil conditions may require the use of special tools, such as a hammer system. Special initial augers guarantee optimal control behaviour. The control system for the RS pipe controls uses tilt sensors exclusively; the system for the RS-HV pipe controls is supplemented by the PERFORCAM optical-electronic navigation system in addition to the tilt and angle sensors. This
increases the accuracy. Both RS and RS-HV pipe controls work with the PERFORDAT measuring and data recording unit and a hydraulic control unit for the pipe controls.
