MTBM Guidance System
Navigation control is one of the most critical elements for successful microtunneling. Design criteria installation accuracy is maintained using active laser guidance systems.
A shaft station reference laser is positioned on line and grade behind the jacking frame and protected from disturbance. The laser is projected down the tunnel onto the MTBM’s active target at the design’s line and grade. The MTBM contains three inclinometers read and transmit the MTBMs pitch, yaw, and incline data coordinates. Target sensors relay this data to where it is numerically displayed on the operator’s control console.
FEATURES:
- Light‑sensitive TGS100 target reads the laser beam and transmits x/y coordinates and MTBM incline.
- Detects the point of highest light intensity.
- Two redundant inclinometers measure MTBM pitch and roll.
- Target display shows current and projected cutterhead position.
- System logs 100+ data points for reporting alignment deviation, face pressure, and torque changes.
Testimonials
It is great to see a family-owned company in the tunneling industry continue to succeed and progress with their next generation of leadership at the helm. Akkerman continues to put cutting edge technology in the hands of contractors like ourselves that enable our talented people to do what we love to do: put pipe in the ground precisely online and grade! Whether it’s a guided boring system, a custom-built TBM, top notch field technician support on a Microtunnel drive, or the gathering of the industry’s top experts at one of their “Akktoberfests” to educate us all; they are doing things the right way. Akkerman has played a big role in our company’s success in the trenchless industry and we look forward to working with them for years to come.
