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)
