Medium-Diameter Shield Tunnel Boring Machine

Medium-Diameter Shield Tunnel Boring Machine

Reduces construction period time on tunnel projects and environmental impact, thanks to reuse of main components of shield tunnel boring machine and enhanced driving power force efficiency

Medium-Diameter Shield Tunnel Boring Machine

Changed joining method for main structural parts from welded fixing to bolted connection, thereby simplifying the work involved in construction, disassembly and reuse of components. Switched cutter drive system from hydraulic to electric, improving output torque by 27%.

Product Description

A shield tunnel boring machine that features a structure more conducive to component reuse through the application of a bolt-on method for the joining of main structural parts, in place of prevailing welded fixing. This machine offers improved output torque and less waste oil through a change in the cutter drive system from hydraulic to electric.
