Shipping Tunnel Boring Machines for Tunneling and Construction Projects
A tunnel boring machine can weigh thousands of tons and stretch hundreds of feet, with a cutter head spanning more than 50 feet across. You cannot put one on a truck in one piece. So how does a machine this size travel from a manufacturer to a tunneling site across the world? It comes apart into sections, moves as oversized freight, and goes back together on arrival.
Texas International Freight ships tunnel boring machines and their components from Houston to construction and mining projects worldwide. We plan the disassembled move, arrange the heavy haul and vessel space, handle the customs work, and coordinate the route at both ends.
What a Tunnel Boring Machine Is
A TBM, sometimes called a “mole,” is a machine built to excavate tunnels through soil and rock. The machines are cylindrical, with diameters from a few feet to more than 50 feet and lengths reaching hundreds of feet. A rotating cutter head at the front grinds through rock and soil, conveyor belts or screw conveyors carry the spoil out, and a segmental lining system installs pre-cast concrete rings that support the tunnel as the machine advances.
Types of Tunnel Boring Machines
Each TBM type suits a different ground condition. Earth Pressure Balance (EPB) machines work in soft ground, using the excavated material to hold the tunnel face. Slurry Shield machines handle water-bearing ground with a slurry that balances pressure at the face. Hard Rock TBMs use disc cutters to break solid rock. Mixshield machines, a hybrid of EPB and Slurry, take on mixed ground and transitions between soil and rock.
Where TBMs Are Used
TBMs build the underground infrastructure cities run on, excavating tunnels with little disruption at the surface. They cut subway lines, road tunnels that ease congestion, and utility pathways for water, sewage, and power. The Gotthard Base Tunnel in Switzerland, the world’s longest railway tunnel, runs 35 miles through the Alps on TBM-bored sections. The Channel Tunnel between the UK and France was excavated with TBMs, and Seattle’s downtown road tunnel was bored by a machine named “Bertha,” one of the largest ever built.
Disassembly for Shipping
Because a TBM can weigh thousands of tons and span hundreds of feet, it is broken into sections for transport: the cutter head, the shield, and the trailing support gantries. Each part is labeled and tracked so the machine reassembles correctly at the destination. Planning the breakdown up front keeps the components organized and accounted for through the move.
Specialized Equipment and Route Planning
Moving TBM sections takes heavy-duty cranes, flatbed and barge transport, and breakbulk vessels, with every piece fastened and balanced to prevent damage in transit. Route planning maps around low bridges, narrow roads, and weight-restricted areas, often with route surveys and coordination with local authorities. Skilled crews who understand TBM construction handle the load at each stage.
Customs and Compliance
Shipping a TBM across borders means meeting each country’s rules for oversized and heavy cargo. The work covers securing the permits and coordinating with a customs broker so the components clear without delays or added cost. Getting the compliance right keeps a high-value machine moving instead of waiting at a border.
Working With Texas International Freight
Texas International Freight handles the logistics of heavy machinery, including tunnel boring machines, from the disassembled plan to the heavy haul, the ocean leg, and the customs work. The same desk runs the wider construction freight behind a tunneling project. Tell us the machine, the components, and the destination, and we map the move.

Connect With Us:
Can a tunnel boring machine ship assembled?
No. A TBM is far too large and heavy to move in one piece. It is disassembled into the cutter head, shield, and trailing gantries, then reassembled at the site after the sections arrive.
How heavy is a tunnel boring machine?
TBMs can weigh thousands of tons and run hundreds of feet long, with cutter heads spanning from a few feet to more than 50 feet across. The size and weight put the move squarely in oversized and heavy freight.
What transport modes does a TBM move use?
A mix. Heavy-duty cranes and flatbed or barge transport carry the sections to and from the port, and breakbulk vessels move them across the water, each piece fastened and balanced for transit.
Why is route planning important for TBM transport?
The sections are oversized, so the route has to clear low bridges, narrow roads, and weight-restricted areas. We run route surveys and coordinate with local authorities to keep the move safe and on schedule.
How do customs work for an international TBM shipment?
Each country sets its own rules for oversized and heavy cargo. We secure the permits and work with a customs broker so the components clear without delays or added cost.
