Short Description:

1.Dual drive power head, maximum output torque: 100KN.M
2.Expansion chassis(double-width ). The operating width is 3600mm and the transport width is 2600mm. The equipment has good passability and high construction stability.
3. The maximum drilling depth is 16m. It can realize the large drilling diameter construction through different drilling tools and construction methods;
4. High traction for walking. The whole machine is flexible can meet the requirement of 20° ramp for normal driving;
5. Solid chassis which is low center of gravity and easy to move in short distance.
