  Substantive double cutterhead TBM experiments realize electricity conservation

  Abstract: TBM operations require huge amounts of electricity. In reducing the amount of electricity required by the cutter drive unit a double cutterhead system that allows for greater energy conservation during excavations using a TBM has been developed as an improvement to the conventional single cutterhead system. The double cutterhead system is an energy conservation technique that optimizes the...
