High product quality is the basis for everything at Herrenknecht. Concentrated expertise of German Engineering in over 80 locations worldwide.
For fast and economical crossing under obstacles, Herrenknecht horizontal directional drilling rigs with four different base configurations are the perfect choice for any job. With excavation diameters between 0.2 and 2 meters, the variants offer pulling forces between 60 and 600 tonnes.
With drive lengths of up to over 1,500 meters, Direct Pipe® combines the advantages of microtunnelling and horizontal directional drilling technology so it can be used in all geologies. In just one step, the borehole is created and the pipeline pulled in.
The efficient one
Thanks to innovative control and navigation systems, a jet pump for muck removal and an integrated hydraulic power unit, E-Power Pipe® enables over 1,000 meter long drives with small diameters and low overburdens.
The game changer
A revolution in HDD. Three innovative drilling tools lead to the desired diameter in just one step: the Full Face Hole Opener, the Downhole Jet Pump and the Weeper Sub.
With the help of AVN machines, conduits for the subsequent installation of pipelines can be created safely even in difficult geologies and on long crossings of over 1,000 meters – both in segmental lining and pipe jacking, in all geologies and with diameters of up to 4 meters.
Support for pipeline installation is provided by the Pipe Thruster with push and pull forces of up to 750 tonnes. The Pipe Thruster sets new standards and is at the same time power reserve and rescue tool. On the way to even longer pipelines with large diameters or in difficult geologies.
For the semi-trenchless installation of pipelines, the newly developed Pipe Express® technology needs only a narrow corridor for the alignment and without lowering groundwater. With lengths of up to 2,000 meters and diameters between 900 and 1,500 millimeters, Pipe Express® can reduce corridor width by up to 70%.
The compact one
With diameters ranging from 0.1 to 1.4 meters over distances of up to 120 meters, the auger boring machine is based on a simple and clever principle: the auger transfers the torque from the drive to the cutterhead and simultaneously removes the excavated material.
The flexible one
With entry angles between 8° and 90°, Slant Directional Drilling rigs (SDD) combine the strengths of horizontal and vertical drilling technology to safely and efficiently tap near-surface raw materials up to a maximum depth of 1,700 meters.
