The start-up phases of an excavation by TBM sometimes require specially designed structures used to counter the initial push.
As is often the case especially in projects involving the realization of metro lines, the TBM must excavate different sections connecting the areas in which the stations are being built. Between each breakthrough and the starting point of the subsequent excavation tract, it's more efficient to transport the TBM using dedicated devices instead of using the machine's own advancement means.
TunnelPro can design thrust frames, push rings and similar equipment for the start-up phase, according to the project needs and the client's requests, as well as push-trolleys, transport cradles and similar equipment for station crossings or other TBM translation phases.
