Machining of erector segments for a TBM
Mechanical machining of erector segments for a TBM (Tunnel Boring Machines)
We have recently carried out the mechanical machining of 4 sectors of a erector for a TBM (Tunnel Boring Machine).
The next step will be the assembly of the four machined erector sectors to create the rotating ring of the erector which will measure 9 meters in diameter.
The erector is for a tunnel boring machine for an excavation project in Japan. The TBM in question, with a 13.2 meter wide cutter head, will be used to bore a tunnel for the construction of lane 5 of the Hiroshima expressway (the Hiroshima Project).
