Tunnel Boring Machines
If you are in the trenchless industry, you are sure to be familiar with the legacy that Akkerman TBMs have created. While this time-tested and proven technology has been successfully installing thousands of tunnels around the world, we have been busy advancing the technology to maximize performance, expand capabilities, and increase versatility.
FEATURES:
- TBMs can operate in pipe jacking or two‑pass tunneling modes.
- Easy to operate with on‑board manual controls.
- Accurate and reliable tunnel laser guidance with three‑point sealed articulation.
- Interchangeable cutterhead allows underground swaps if ground conditions change.
- Closed‑face attachments and screw augers available for raveling ground.
- Disc cutter heads available for rock up to 15,000 psi.
- On‑board methane gas detection system.
- Easy access to the face for obstruction removal.
- High‑capacity TBM bearing with powerful two‑speed hydraulic drive.
- Optional Earth Pressure Balance mode up to 1 bar.
- Increase kits available for all TBM models; diameters can be adjusted to match product pipe.

Testimonials
Lithos Engineering is focused on providing tunnel design and construction management for underground construction projects across the United States and has worked with many different tunnel contractors on projects of varying sizes and complexity. I am always happy
to see Akkerman equipment on our project sites and I know we can rely on Akkerman products for a high level of performance and reliability.
I had the pleasure of working with Akkerman on one of our projects for which they designed and constructed a project specific hard rock TBM for a curved water conveyance tunnel high in the Rocky Mountains of Colorado. Akkerman not only provided great solutions and technical support for the project but was a pleasure to work with in a collaborative teaming environment that allowed us to not only reduce project risks but reduce construction costs and schedule. During that project, I visited the Akkerman production facility to inspect the TBM under construction; I was extremely impressed with the Akkerman management, staff, and systems for quality control. I look forward to a long future of working with Akkerman and their products on our tunneling projects.
