The Barbco Tribor is a hybrid of three types of machinery: an auger boring machine, a guided boring machine and a horizontal directional drill. Tribor is available in three models — Tribor30, Tribor36 and the Tribor48.

Burrs are categorized as Poisson burr, tear burr, and rollover burr based on the engagement of end mill cutter and workpiece material.

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.

There is a giant serotonin-containing neurone (GSC) in each cerebral ganglion of Helix pomatia and Limax maximus. In Helix, presynaptic endings of the GSCs are located in the buccal ganglia and peripheral musculature. Dense-cored vesicles of mean diameter 100 nm were observed in the perikarya and the axon branches of the GSCs within the cerebral ganglia. Evidence is presented which suggests that these vesicles sequester serotonin. Vesicles with a similar appearance are present in the presumed presynaptic endings of the GSC in Helix. These endings selectively accumulate tritiated serotonin. Axonal processes containing agranular vesicles (mean diameter 50 nm), or granular vesicles (50–100 nm diameter), or both, make close contact with the fine axon branches of the GSCs within the cerebral ganglion neuropile. Some of these axon processes appear to be presynaptic endings making synaptic connections with the GSCs.

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.
