Trenchless solution

25 April 2008

Installation of a New 6,5 Km Long 20 Kv Electricity Cable between the towns of Eschenhof and Hohenrot in Germany has been fast tracked through use of trenchless technology. Föckersperger used a Tracto - Technik F 150 cable plough with a soil displacement hammer to install 5 km of the cables for main contractor Benningern in just three days.

The 17 tonne F 150 plough, which was towed by a Unimog, was fitted with four rubber wheels on adjustable booms to allow it to cope with uneven terrain. The plough also has an adjustable track width of between 2 and 6 m that enables it to drive round any obstacles.

The final 1,5 km of cable laying, which will strengthen the local electricity network, had to be carried out through the streets of Weldingfelden and was undertaken by Benningern.
