The HDD20-E, together with the combined mixing truck, impresses here with its closed and self-sufficient system. The boost function, which temporarily enables a pulling force of 25 tonnes, and the electrification stand for high performance while conserving resources.
The contract runs until autumn 2026. There are particularly high requirements with regard to the low tolerance range in the position and depth of the boreholes, the strict specifications of archaeology, geology, hydrogeology and ecology, and the high safety standards.
