Schwanau, Germany, April 15, 2013. At bauma 2013 in Munich, Herrenknecht is presenting its new "Herrenknecht Approved" quality seal for the first time. This certificate offers construction companies additional security when buying used tunnel boring machines of the AVN type, HDD rigs as well as the corresponding containers and power packs. The seal is given to used machines after they have been thoroughly checked in line with proven Herrenknecht quality standards and the original functional state has been restored.
"A 9-month warranty guarantees the full functionality of every Herrenknecht used machine with the Approved quality seal, so that our customers can realize their upcoming projects reliably and safely", said Ulrich Schaffhauser, Chairman of the Executive Board Business Unit Utility Tunnelling.
