Micro Tunnelling Equipment, Tunnelboring Machines, Shaft Excavation Equipment, HDD Equipment, Auger Boring Machines: More than 850 Herrenknecht Utility Tunnelling Machines are in operation around the world constructing or laying water & wastewater systems, gas & oil pipelines, as well as conduits for electricity and telecommunications.
Trenchless tunnelling technology offers a range of advantages compared to conventional construction procedures: transport, business and the environment remain mostly undisturbed when micromachines, HDD rigs or shaft sinking equipment, innovations such as Direct Pipe® set new standards for semi-trenchless installations.
The new technology E-Power Pipe® allows the secure and quick installation of underground cable protection pipes with smaller diameters and long advance lengths. Innovative HDD tools simplify pipeline construction operations at key-sections.
Herrenknecht’s portfolio is completed by a broad range of products for mining & exploration.
The boring machines offered by Herrenknecht in cooperation with Bohrtec GmbH stand out in comparison to conventional construction methods due to their technical, economic and ecological advantages. Their main range of application is underground pipe jacking with comparatively small diameters, from 0.1 to 1.4 meters with drive lengths of up to 120 meters.
Herrenknecht offers a powerful horizontal directional drilling technology for trenchless pipeline installation. With horizontal directional drilling technology from Herrenknecht, pipelines can be installed rapidly, economically and with minimized impact on environment and existing infrastructure. Later application of the pipelines include the transportation of oil & gas, sewage water, district heating, high-voltage power lines, cable bundles for telecommunication and more.
Herrenknecht AVN or Slurry Machines with a cone crusher are all-rounders for safe tunnelling in the diameter range of 0.4 to around 4 meters. These microtunnelling experts show their full potential particularly in non-accessible machine sizes. The slurry-supported excavation concept makes it possible to use these machines in all kinds of ground conditions, ranging from silt to clay to incohesive soils, and further to gravel and rock.
