XR420E

The intelligent control system realizes the vertical automatic adjustment and display of the drilling mast, automatic rotation, automatic soil throwing, automatic control of the long spiral construction method for grouting, and pile type display functions. It adopts a bus panel design to effectively prevent misoperation;
Adopting a double boom amplitude mechanism and a hydraulic telescopic track chassis specifically designed for rotary drilling rigs, equipped with large-diameter slewing supports, it ensures super strong stability and convenient transportation;
Adopting Cummins engine, it has strong power and three gear power control. Users can choose the corresponding gear according to the working conditions, realizing the effect of three engines on one drilling rig. The optimized three gear power curve effectively reduces fuel consumption and usage costs;
The hydraulic system adopts load sensing technology, superimposing total power control and limit power control technology to make the hydraulic system more efficient and more energy-saving;
The single row rope main winch structure effectively solves the problem of wire rope "biting rope" Greatly extended the service life of the steel wire rope;
The power head has standard mode, rock entry mode, and energy-saving mode, and users can choose the corresponding mode according to different geological conditions, which improves construction efficiency while reducing fuel consumption;
Multiple configurations: optional winch pressurization, casing drive, etc., with good expandability;
Equipped with a centralized lubrication system as standard, maintenance and upkeep are more convenient, improving work reliability.
