The telescopic crawler chassis with swing legs is adopted to meet the stability of large tonnage drilling rig and the convenience of disassembly and transportation, it is equipped with large diameter slewing bearing with stronger anti over turning ability. The power head adopts vertical pin shaft connection type power box and bracket, which has high reliability and is convenient to disassemble, the power head has common mode, rock entry mode, medium speed rock entry mode and energy-saving mode, and users can select corresponding modes according to different geological conditions, which improves construction efficiency and reduces fuel consumption, The main winch adopts single row rope, the service life of steel wire rope is 2~4 times longer than that of multi-layer rope, and the use cost is lower. The main and auxiliary hydraulic systems adopt load sensitive control technology, with fast response and good control performance, the double overhead cooling system is adopted, which can intelligently adjust the cooling capacity according to the temperature, with strong cooling capacity, energy saving and noise reduction, Equipped with electronic control turbocharged engine, it has strong power, low fuel consumption, convenient and fast service, and adopts decentralized independent cooling system, with strong cooling capacity and low noise.
