Tunnel Service Group

Highly flexible modular design: Hydraulic unit for cutting wheel drive can be operated from inside the container (for short, small diameter drives) or easily taken out and used as a tunnel aggregate behind the machine (for longer, larger drives).

No additional investment necessary, full exchangeability of containers on your yard ensures maximum material availability, avoidance of downtime and optimized spare parts stock.

Compatibility with existing microtunneling systems of other manufacturers (ask us for details).

Separation of cutting wheel hydraulics from large jacking tank system avoids contamination of the large oil volume with dirt particles from hydraulic tunnel hoses, resulting in lowered cost through longer life times of oil and hydraulic components.

Double to triple redundancy of many systems to avoid downtime by failures.

Data logging of 24-pin PLC machines and 37-pin analog machines.

Air supply for bentonite system, slurry gates and other pneumatic functions

Soft start of cutting wheel drive for increased component life time and less generator load, enabling smaller diesel generator units

Frequency-controlled jacking pump system for increased component lifetime and optimized energy efficiency
