What we have done so far. Lots of exciting project coming up.
  • T228 - TBM Assembly

    Project T228, assembly of Hitachi Zosen EPB TBM on sloped tunnel flooring.

    Deployment of:-

    – Skid Sliding System for the horizontal maneuvering of TBM on tunnel floor.

    – Smart Gripping Hydraulic Jack for pulling of TBM on cradle.

    – Synchronous Hydraulic Jack operation on vertical lifting/lowering of TBM.

    Pioneering the use of Hydra-Slide’s innovative sliding method featured in major industrial news online! (Click image to learn more)
