Application of Domestic Manufactured Hydraulic Cylinder Pile Frame Luffing System to the Engineering Barge Reforming Works

Through the reformation of two floating pile drivers,the application shows that using the domestic manufactured hydraulic cylinder pile frame luffing system is reliable.It is not only an innovation in aspect of the special old engineering barge reforming works but also a big expenses saving comparing with the new building of one pile driving barge and the import of the foreign made hydraulic cylinder ones,as well as to promote the related industry technologies progress.
