RASA Pipe Jacking Machine
RASA’s most popular pipe jacking machine series, the DH, is capable of handling pipe size of 250mm to 3000mm (internal diameter) and excavating through a variety of ground conditions including boulder, soft rock, medium hard rock, and hard rock layers. By changing its customisable cutter disk, the machine can also be used in ordinary soil, hard soil, and cobble gravel layers.
The machine adopts a two-stage crushing mechanism. Primary crushing is performed by roller bits installed on the cutter disk that rotates at a large torque, followed by secondary crushing performed by a robust cone crusher located behind the cutter face.

With a variety of cutter disks for different ground conditions, the cutter head can be customised for the best excavation performance.
