The Robbins Company revolutionized tunnel construction when our engineers designed the first hard rock TBM and we have never stopped leading the industry in innovation. From the design and stabilization of the cutterhead to the rapid removal of muck, we know what it takes to manufacture the most efficient tunneling machines.
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.

A tunnel boring machine (TBM) also known as a “mole“, is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through hard rock, sand, and almost anything in between.
A tunnel boring machine (TBM) is a piece of equipment designed to bore circular tunnels through dense, hard rock, relatively soft sand or any substrate of any hardness between the two.

Tunnel Boring Machines Contractors rely on Robbins Single Shield TBMs in massively fractured rock. When you have large sections of broken ground to bore through, your project risk can be significant. The Robbins Single Shield TBM provides the rock boring capability of a Robbins Main Beam TBM and protects against rock collapse like a Double […]
A precise TBM (Tunnel Boring Machine) market segmentation is done on the basis of vendors, geographies, applications and TBM (Tunnel Boring Machine) types. The study also covers equipment, upstream raw materials, TBM (Tunnel Boring Machine) marketing channels, and downstream client survey.

Tunnel Boring Machine (TBM) > Tunnel Boring Machine (TBM) The existing tunnels of the CBBT were constructed using an immersed tube method, in which U-shaped trenches were prepared in the Bay bottom for each of the tunnel sections that were previously fabricated and outfitted before being floated out and sunk into place.
KAMY series of Roadheaders offers the best cutting performance in a wide range of rock formations. Equipped with geometrically optimized transverse or longitudinal cutter heads, these flexible machines can be used to excavate subway tunnels, road tunnels, railway tunnels and water tunnels without using explosives.
