Rotary Drilling Rig KR50

Dual drive power head, with a maximum output torque reaching up to 100KN.M, ensuring powerful and efficient performance.
Expansion chassis (double-width ), where the operating width is an impressive 3600mm and the transport width is a manageable 2600mm. This equipment not only showcases good passability but also exhibits extremely high construction stability, enabling it to operate smoothly in diverse conditions.
The maximum drilling depth is an outstanding 16m, and it has the ability to realize large drilling diameter construction through a variety of different drilling tools and construction methods, offering great flexibility and adaptability.
It features high traction for walking, and the entire machine is highly flexible and can easily meet the requirement of a 20° ramp for normal driving, ensuring seamless movement even on inclined terrains.
The chassis is solid, with a low center of gravity, facilitating easy movement in short distances and ensuring stability during operations.
