On Dec. 12, 2012, Herrenknecht AG took over the French manufacturer of tunnel supply vehicles, Techni-Métal Systemes SAS (TMS), based in Livron. By acquiring TMS, Herrenknecht is expanding its full-range portfolio that comprises all technical equipment and services around innovative tunnel boring machines.
TMS designs and produces tired, non-railbound special vehicles used on tunnel construction sites to transport personnel, lining segments, extracted material and other rolling stock. The cooperation between Herrenknecht and TMS has existed since 2007. It has already led to cooperation in diverse projects in which TMS’ special vehicles provided for optimized logistics solutions. TMS vehicles and Herrenknecht tunnel boring machines have been used in projects in the Netherlands, Malaysia and Russia. With the company takeover in December 2012, Herrenknecht is integrating TMS’ specialist knowhow and engineering expertise into its group portfolio.
The multi-service vehicles for heavy-duty transport produced by TMS are self-propelled and equipped with double driver’s cabins. They are driven by powerful diesel engines with an integrated particle filter (exhaust emission standard EPA Tier 3). The power is transmitted by steered drive shafts. All required welding structures are made of high-strength steel. Around 20 engineers and specialists from Techni-Métal Systemes SAS bring their expert knowledge in engineering, design and vehicle assembly with them. In addition, Herrenknecht offers its customers service and supply of spare parts for these tunnel supply vehicles. The vehicles can be used to transport personnel and material both in tunnel construction and in mining.
TMS will be managed by Philippe Fraunhofer (graduated industrial engineer FH) and Pierre-Matthieu Hieber (mechanical engineer) of Herrenknecht AG. “TMS offers state-of-the-art products, which are indispensable for modern tunnel construction, because quicker tunneling performances must go hand in hand with very efficient transport systems in the back area,” says Gebhard Lehmann, Vice Chairman of Herrenknecht AG’s Board of Management. “As a full-service provider in tunnel construction, we are now able to offer our customers an even broader range of additional equipment as integrated solutions.”
Herrenknecht delivers tunnel boring machines for all ground conditions and all diameters – ranging from 0.10 to 19 meters. The product range comprises tailor-made machines for traffic, supply and disposal tunnels as well as additional equipment and service packages. Herrenknecht also manufactures boring systems for vertical and inclined shafts as well as deep drilling rigs. The Herrenknecht Group achieved a total operating performance of 1.104 billion euros in 2011. All in all, Herrenknecht machinery has completed 1,900 km of tunnels in large diameter ranges of over 4.20 meters since its establishment in 1977. The Herrenknecht Group employs around 4,000 people worldwide.
