Features of the entire product series
The entire product line is equipped with international brand engines such as Cummins, CAT and Deutz, with options for China National II, National Ill, and National IV, as well as Euro V to meet the needs of global users.
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.
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.
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.
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.
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.
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.
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.
Many models offer the option of remote control within line-of-sight distance, eliminating safety hazards when drilling on steep slopes or loading and unloading trailers, meeting the requirements of certain regional regulations, and providing user-friendly designs such as camera monitoring and rig body lighting.
