GBM Guidance Systems
For over two decades, Akkerman has revolutionized the pilot tube guidance system technology. Current capabilities have far surpassed industry expectations just a few short years ago with innovative procedures and technology that have allowed installations exceeding 600-lf with pinpoint accuracy.
Using a theodolite with advanced remote-controlled optics set to the desired line and grade, the GBM operator visually tracks the position of the steering head of the pilot tube in real-time. The rugged monitor and controls are purpose-built specifically for pilot tube installation to avoid any contact with the theodolite once set-up.
For contractors that require electronic data logging throughout the alignment, an optional data logging package can be installed on your GBM system to record navigation metrics as well as machine parameters along the alignment.
FEATURES:
- Optional: Pilot Tube data logging technology capturing installation parameters every 5 seconds.
- Optional: Smart Target Technology allowing display setting changes, sleep mode activation, and high‑temp warnings without retracting pilot tubes.
- Standard LED targets use replaceable batteries with battery life measured in weeks.
- Akkerman GBM guidance systems can be customized to fit other pilot tube manufacturers’ equipment.
- Guidance systems are adaptable and usable on any Akkerman GBM system.
