Multi-Joined Pile Driving Machine with a Computer Assisted Guiding System

Today, in big cities of Japan such as Tokyo, a number of urban renewal and infrastructure development projects are on. Because of restrictive work site conditions in urban areas, such as overhead roads or railways, compact construction machines with high mobility are favored. To meet this need, we developed a new type of pile driving machine: HITACHI RX 2000.

With this machine, a piling attachment, such as an earth auger or vibratory hammer, is directly connected to the tip of the multi – jointed pile driver arm. The pile driver arm uses the computer-assisted guiding system that allows the arm tip to move in perpendicular or horizontal directions with ease. We call this new system "arm tip locus control".

As of today, the RX2000 has been applied to many H-steel-piling and sheet-piling work in the field.
