Tunnel Service Group GmbH takes pride in providing all spare parts for a Herrenknecht AVN slurry machine system. We offer basically everything that one may need for a Herrenknecht slurry machine and its steering container or system components such as jacking frames, pumps, separations, tunnel powerpacks and hydraulic and electrical lines.
To name a few exemplary items - for everything else, ask us directly:
Our idea is to keep a base stock of everything that may be needed in technical emergency situations, so we can react quickly if a customer has a problem. Therefore we have a two-storey storage with wear parts and spares for microtunneling machines. For bigger requests we have placed call-off orders with our suppliers, being able to cope also with large order volumes in short delivery time.
We at Tunnel Service Group GmbH produce own components. Not only main components but also electronic, hydraulic or steel spare components. Each and every part is fully compatible with the Herrenknecht AVN system and is tested and sealed before storage or packing. Examples are the 37-pin electrical connecting boxes for the machine signals, shaft remote controls, bentonite stations or PLC grease controls for slurry pumps.
Some things have to be made by specialist companies. In these cases we work together with most of the suppliers of the market leaders, being able to provide you with OEM quality at an affordable price range. Our call-off orders allow us to offer an attractive prizing as well as short delivery times in case something should be out of our own stock.
