working conditions
This series of separated DTH (Down-the-Hole) drill rigs has been primarily used in small and medium-sized quarries, cement mines, open-pit coal mines, and preliminary site preparation for large-scale open-pit mines. They are also applied in infrastructure projects such as highway construction and real estate development. Equipped with 3.5-inch or 4-inch hammers, they achieve optimal performance for hole diameters of Φ115mm, Φ138mm, and Φ152mm, boasting high drilling efficiency and excellent dust collection capabilities. With exceptional flexibility and mobility, this series is particularly well-suited for operations in confined work areas. It has been successfully deployed in mining, military projects, road construction, water conservancy, rock excavation, and other fields, earning widespread recognition from customers both domestically and internationally.

Features of the entire product series
The entire series of DTH drill rigs use two-stage compression air ends with optimal energy efficiency ratios to achieve high air pressure rock drilling, which has excellent fuel economy performance and is more environment friendly.
The ROPS and FOPS certified air-conditioning with cooling and heating functions, conforms to principles of ergonomics, providing a broaden view, safe and comfortable experience for the operator.
Equipped with a high-strength aluminiu alloy feed beam and a stainless steel protective cover;The distinguished guidance quality and stability contribute to the achievement of high-precision drilling; The feeding system consists of hydraulic cylinder + steel wire rope or motor + chain and hose follower, realizing feeding in fast or slow speed.
The enlarged air filter and oil filter guarantee the long service life of such functional components as the engine, the screw air end and oil pumps; ln line with actual working conditions, an additional pre-separator at the front end can be assembled to satisfy the requirements of a more demanding environment.
The special-designed efficient dry type dust collection system has a large filtration area; Equipped with an optional mature wet type dust collection system; A combination of dry and wet types dust collection system solves the problem of flying dust during hole collaring, meeting the highest level of environmental protection requirements.
The dual-speed tramming motor and the oscillation cylinder of -10°to +10°oscillation angle ensure stable and smooth high-speed movement on flat areas and off-road performance on pristine landform.
A combination of the hydraulic motor or high-power rotary head driven by the hydraulic cylinder and the patented absorber, greatly lowers the possibility of jamming and prolongs the service life of the rotary head and drilling tools.
Electro-hydraulic operating system, which is very convenient for adjustment and operation; The adoption of intelligent multi-function controller and CAN com- munication realizes real-time monitoring of drilling operating conditions; All-round automatic protection and maintenance reminder function.
To meet customer demands, the series products are designed with various options: high altitude, high ambient temperature, extremely cold areas, automatic lubrication system, automatic fire extinguishing system, hydraulic rear support leg and other functions.
The loT system is designed for the drill rig with rod changing function, to achieve long-range locating, locking, data monitoring and parameters adjustment, etc.
