SG Hydraulic wall grab successfully serviced the Xilong hydro-junction projects

2009-09-24

In July, builders worked in the Xilong hydro-junction projects in Hubei province day and night, and got the phase victory before the flood period of Hanjiang River catchment. From May to July, about thousand workers finished the cut-off walls, our SG machines have successfully serviced the projects.


 

As the key projects of South-to-north Water Transfer Project, Xilong features short working time, high quality. The cut-off wall is the main part to protect the hydro-junctions, and digged in the shore of Hanjiang. So it is the key point and difficult point. The builder chose our SG wall grabs before working to dig a wall, 66m depth and 0.8m width. SG40A and SG40E have standed severe tests and finished the cut-off walls. They are praised by the builder and user for their performance.

SG40A、SG40E’s good performance is the outcome of our pursuit. It will inspire us keep moving and contribute to more projects.
