| 22.11.2011 |  | GRUNDORAM assisted Horizontal Directional Drilling in Saudi Arabia
Ramming machines are typically used to install steel pipes underneath traffic and waterways. In pipeline construction these machines are also applied to assist or rescue HDD bores. The Grundoram Taurus was recently used by Saudi Arabian company GBP for a so-called "pullback assist". The rammer's impact energy of 18.600 Nm assisted in installing a 48" steel pipe along the Aramco Manifa to Saphaniyah pipeline. |

| 19.09.2011 |  | Underground cabling in rock beneath railway line, motorway and main road
It was almost a year ago that the company Clemens Reuschenbach in Germany was involved with ground cabling measures for the connection service line from the villages Puderbach to Oberhonnefeld with two 20 kV cables and a glass fibre cable. The reason for the measure was the deconstruction of the 20 KV open line from SÜWAG Frankfurt, to make the power supply more secure.Now the time had arrived to close the gap over a total length of 375 m beneath the high-speed inter-city railway line from Frankfurt to Cologne, the A3 motorway and the L 265 main road close to the waste deposit site of the Neuwied district. The ambitious bore project was carried out by the company Clemens Reuschenbach, together with their sister company REVOR GmbH.
