When line and grade are critical to your project’s success, the Barbco Boring Machine Tunnel Attachment (BMTA) is the equipment of choice. Designed for large-scale tunneling, the BMTA features an individually powered cutting head, separate from the boring machine’s power supply. The attachment’s controls provide 360-degree steering control, so you can ensure the accuracy of your bore.
Designed for soft-ground and mixed-ground bores, the BMTA ranges in diameter between 48″ to 120”. It’s also equipped with a quick disconnect ring for easy detachment from the casing when the bore is complete.
