1. The pin shaft is used to connect the non-telescopic crawler chassis, which can meet the stability of over-tonnage drilling rig and the convenience of disassembly and transportation. The ultra-long wheelbase is more adaptable to the formation.

2. Double large vertical plate box rotary platform structure, more stable and reliable operation;

3. The power head adopts zhuolun double speed ratio reducer with 250 motors, realizing the function of high and low speed.

4. The main and sub-winch adopt single-row rope technology, the life of wire rope is 2~4 times longer than multi-layer rope, and the use cost is lower;

5. The upper set of the main winch, use pin shaft connection, high connection strength, convenient disassembly. Box structure main winch bracket, safe and reliable structure. The main winch meets the working condition of M6, and the life of reducer can reach up to 10000h.

6. Hydraulic main and secondary systems adopt load sensitive control technology, with fast response and good control performance;

7. Intelligent heat dissipation control system can reduce energy consumption and realize energy saving.

8. Intelligent auxiliary construction technology: automatic adjustment of the perpendicularity of the drilling mast, automatic rotary positioning, automatic throwing of soil by the power head, and automatic rotation of the power head.

9. The chassis is equipped with transport legs, making it easier and safer to disassemble and assemble in the field;
