The whole machine is transported without removing the drill pipe, which reduces the logistics cost and improves the transfer efficiency. Some models are equipped with the crawler telescopic function when they get off the vehicle. After the maximum extension, it can ensure the transportation efficiency.
The stability of the whole machine during construction is ensured through reliable structural engineering and stable crawler extensions.
The power system adopts domestic or international well-known brands, including Cummins, Mitsubishi, Yangma, Weichai, etc., with stable, efficient, environmental protection. At the same time, it is quiet and economical, and meets the troubleshooting requirements of the national IL stage.
The hydraulic parts are mainly made of Rexroth, Brevini, German wormwood and Doosan. Combined with the international concept, the pump valve is completely designed in accordance with the product characteristics of rotary drilling rig. Specially designed, the auxiliary system uses the load sensitive system to realize the flow on-demand distribution.
The power head is equipped with domestic first-line brands and all major engine plants in the industry, which has the advantages of high torque, reliable performance and convenient maintenance. The electrical control system, using main parts from imported brands and cables with aviation connectors, is sealed, waterproof, and ensures stable performance on its large display screen.

The layout of the platform on the whole machine is reasonable, which is convenient for the subsequent maintenance of the equipment. Operation control achieves simple, beautiful, and high recognition. The structure is designed according to parallelogram, and the hoisting cloth is placed on the mast or boom, which is convenient for observing the direction of steel wire rope. In case of disordered rope, it can be found and rolled in time.
The simple use of double broken line design can realize multi-layer winding of steel wire rope without rope biting, reduce mushroom damage and improve the service life of steel wire rope.
