1. The H-type hydraulic telescopic crawler chassis for rotary drilling rig is adopted and equipped with large-diameter slewing support to ensure the super stability and convenience of transportation;
2. The hydraulic system adopts load sensing technology to make the hydraulic system more efficient and energy saving; Three-in-one combined radiator system, compact structure, high cooling efficiency;
3, the use of imported Cummins engine, strong power, enough power reserve to meet the plateau construction, noise, emissions to meet the Euro Ⅲ standards;
4, the use of a unique large triangle luffer mechanism, large drilling mast section, improve the stability of the equipment working device, to ensure the construction of large holes, super deep pile hole quality;
5. Xugong D series single-row rope main winch structure, the main winch wire rope can meet the single-row rope winding under the state of full drilling depth, effectively solve the "rope bite" problem of wire rope, greatly extend the service life of wire rope;
6. The power head has the common mode and the rock entry mode, respectively for the soil layer and rock layer operation, improve the construction efficiency;
7, a variety of configurations: optional winch pressure, off leg cylinder, sleeve drive, good expansibility;
8, standard centralized lubrication system, more convenient maintenance, improve the reliability of work.
