Besides our standard data solutions we can also customize your system. You like a data system that we have on offer but you need more functionality? You want us to change or upgrade your existing software or PLC system? You have a completely new challenge that is not available on the market or only at a prize range way beyond what you can spend?

Upgrades and system changes

 
Siemens S7 solution in power pack

The idea of Tunnel Service Group GmbH  is to offer and explain your options and then let you decide what you really want. This means for example that you don't have to upgrade a Siemens PLC S5 system; we can still offer you the full service for Siemens S5. But sometimes there are still reasons to change a system or upgrade it to a new standard.


We at Tunnel Service Group GmbH have experience upgrading existing systems. Be it an upgrade to a Siemens S7 control systems, a hydraulic change or a simple power increase for example for your slurry pumps - our engineers and technicians are ready to help you. Ask us for a recommendation and a quote.

 
  • Siemens PLC S5 upgrades to S7
  • Power increases for slurry pumps
  • Hydraulic optimizations
  • Additional features for existing systems
  • ...
 
 

Project Example: DN800 Powerpack

Powerpack AVN800B with upskin to AVN800A

Our engineers realized what everybody said was not possible: Tunnel Service Group GmbH built a fully functional hydraulic tunnel powerpack with an outer diameter of only 975mm, designed to work with a Herrenknecht container and an AVN800 drilling machine. And we are proud to say that on its first drive it broke the DN800 direct pipe record in North America.  Find more about our latest success:
