We were the first started mechanized TBM serial production on the territory of ex-USSR. These TBMs are used in any geological conditions – from unstable water-saturated soil (quicksand) to hard rock; with any type of strata consolidation. In soviet period, world records were established using the equipment designed by our specialists i.e. tunnel construction speed was 1200 m/month (diameter 5,6m). Our company has experience of TBM construction on the territory of ex-USSR.

TBM are manufactured with different diameter from 1,8m to 6,2m. Depending on geological condition different effectors are used.

  1. excavation effector,
  2. milling,
  3. rotary with picks, rolling or combination rock-destroying tool
