The drilling rig is equipped with a motor pump/diesel pump dual power system.The two pump groups work independently The motor pump system is used during drilling operations and short-distance relocation to save costs.Compared with diesel engines, the cost of using electric pump sets is reduced by nearly 50%realizing energy saving and emission reduction.

 

HIGH DRILL FRAME SYSTEM

The propulsion system of high drill frame and long drill rod, the length of a single drill rod can reach 10 meters, the drilling depth is large at a time, and the auxiliary operation time is reduced; the drill rod storage is a swing storage structure, which can store 2 drill rods The automatic connecting and unloading rod action is simple and reliable, reducing the labor intensity of the operator.

 

FLEXIBLE SWITCHING OF DUAL WORKING CONDITIONS

The high torque power head and the high pressure and high flow air compressor can realize two working modes of down-the-hole and cutting Under hard rock conditions,choose the down-the-hole operation mode, which has high efficiency; Under soft rock conditions choose the cutting operation mode, which has fast drilling speed and good economy.There is no need to start the air compressor during walking and debugging,which is more energy-saving

Featuring a modern design with exceptional recognition, this drilling equipment boasts a robust construction and a versatile multi-degree-of-freedom drill boom. It is capable of multi directional drilling, including horizontal, vertical, and various angled holes, providing unparalleled flexibility.

The pushing beam is meticulously crafted through cold drawing on double-sided guide rails, ensuring high strength and excellent guide precision. The floating chassis, with a track frame that swings ±10°, delivers powerful driving force, rapid movement, and strong cross-country capabilities, making it well-suited for challenging terrains.

Despite its strength, the equipment is lightweight and compact, designed with a family-friendly aesthetic for convenient transitions. Station maintenance is made easy with accessible maintenance points and high part universality.

Certified with Cab ROPS and FOPS Certification, the equipment offers a good view, an exquisite layout, and a safe and comfortable operating experience
