Akkerman® Microtunneling

Face access, peripheral drive Microtunnel Boring Machines (MTBMs) are available in standard sizes 72-114-in.

OD to precisely complete extended and curved* tunnels with exceptional drive and cutting torque. This new generation of MTBMs enables face access to replace cutter head tooling to tackle the complex alignments that our industry demands. The peripheral drive, face access MTBM family features an onboard electric over hydraulic power pack for cutter head drive with low, medium, and high torque modes for accurate control in changeable geology. Back-loaded tooling mounts on the cutter head make access and replacement of worn tooling a simple process without the need for a planned maintenance intervention. Soft ground, mixed ground and rock cutter heads and crushing cones are hard faced to withstand wear. Cutter heads can be customized for specific ground conditions.

Center drive Microtunnel Boring Machines (MTBMs) accurately install pipe in virtually any ground condition, and especially in high levels of ground water. MTBMs feature high pressure jetting nozzles, an articulated steering joint with three-point steering control, and hydraulically activated dirt wings to minimize MTBM roll. The guidance system relays all critical operation data to the control container using a proprietary control software programs. Additional MTBM attributes include a live, one-way audio system and camera allowing for system monitoring during operation, gas detector and submersible pump. MTBMs can be outfitted with increase kits for adaptability. The soft ground and mixed ground cutter heads and crushing cones are hard faced to withstand wear. Cutter heads can be customized for specific ground conditions.
