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.
- TBMs can be used in pipe jacking or two-pass tunneling operation mode.
- Easy to operate. On-board manual control operation.
- Accurate and Reliable. Tunnel laser guidance with three-point sealed articulation.
- Interchangeable cutterhead. Standard cutter head is interchangeable underground 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.
- Access to the face is readily available for obstruction removal.
- High capacity TBM bearing with powerful two-speed hydraulic drive system.
- Optional Earth Pressure Balance Mode to 1 bar.
- Increase kits are available for all TBM models. Akkerman will adjust diameters to match product pipe.

12 years ago, we purchased our first Akkerman equipment. We own two Akkerman TBM spreads and we have nothing but favorable things to say about Akkerman and their equipment.
