About Us
When Martin Herrenknecht founded Herrenknecht GmbH in 1977, no one knew the groundbreaking success that would set in motion. From the passion of a small team of technology-loving engineers, a globally operating group developed. The thirst for progress created milestones in tunnelling technology. And from the courage to prove themselves evolved masterpieces of tunnel construction. But that's nowhere near the end of the adventure: the future promises more.

BOXHOLE BORING MACHINE (BBM)
Product Detail
BOXHOLE BORING MACHINE (BBM)
The BBM technology was developed by Herrenknecht for the rapid and safe construction of vertical and inclined raises or shafts, so-called slot holes. It can be used in stable rock formations and enables drilling diameters of up to 1.8 meters with a maximum drilling length of 70 meters. In developing this technology, a particular focus was placed on improved occupational safety, higher productivity and an optimum mobility of the rig. The time-consuming preparation measures required for conventional methods are no longer necessary.he concept of the Boxhole Boring Machine (BBM) is based on the field-proven pipe jacking technology. A drilling unit at the head of the pipe string is pressed forward from the launch point. Further jacking pipes are installed one after the other in the pipe string and pushed forward, thus lengthening the jacking route. These innovative machines are designed for stable rock with compressive strengths of 180 Megapascal and more. A cutterhead excavates the rock at the tunnel face, which then falls through the center of the rig due to the force of gravity. The removed material is transferred to a muck chute at the jacking frame via channels introduced into the jacking pipes. From there the material can be transported out of the tunnel without problems. After each jacking stroke, the drilling process is stopped for a short time, to secure the pipe string and the drilling unit. Then the next jacking pipe can be installed in the jacking frame.

SDD-RIG
Product Detail
SDD-RIG
Herrenknecht's Slant Directional Drilling rigs (SDD) combine the advantages of two drilling methods that have proven themselves for years. With the specially designed drilling technology, near-surface conventional or unconventional oil and gas deposits and geothermal energy can be developed safely and efficiently. SDD rigs are versatile and can work successfully in virtually all ground conditions.Herrenknecht's SDD rigs combine the technology and advantages of the proven Horizontal Directional Drilling (HDD) and Vertical Directional Drilling (VDD) methods. In both drilling technologies, Herrenknecht has excellent expertise based on years of experience in development and in successful project operations. In terms of machine technology and modularity, the concept of the SDD rigs is mainly oriented towards horizontal drilling technology, while rig and borehole safety, pipe handling and explosion protection are based on vertical drilling technology. The outstanding feature of the SDD rigs is the wide range of possible entry angles: from a very shallow 8 degrees to vertical 90 degrees, so the depth required in the project is very quickly reached. Deposits at shallower depths, for example, can be reached in shorter time at an angle of entry of 30 degrees, since fast horizontal deflection is possible here for drilling further to the targeted deposit. Depending on the drill string and deflection, drilling depths of up to 2,000 meters can thus be reached.

Transportation and jobsite assembly
Product Detail
Transportation and jobsite assembly
The transportation of machinery and components as well as delivery – even to remote areas difficult to access – is one of the first logistical challenges of a tunnel project. Subsequent site assembly and commissioning are also decisive elements of the overall process to ensure that the TBM can start work as planned and reliably. On request, Herrenknecht supports its customers with customized service packages from delivery ex works to commencement of tunnelling on site, including project management and process planning. Ensuring that the ready-to-bore date can be adhered to.

AVN MACHINE
Product Detail
AVN MACHINE
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. Depending on the diameter, this is possible both in pipe jacking and for segmental lining.
