Crawler Mounted Drill Rig Feature:
1. The drill can drill through different strata. The drilling diameter can reach 350mm, and when the final hole diameter is 115mm, --- up to 400m.
2. The drilling rig is equipped with hydraulic technology and two high torque hydraulic motors. The torque can reach 8000n · M. the output speed of the main shaft is 52-135rpm to realize six-stage switching.
3. Two large bore high-pressure propulsion cylinders provide the drilling rig with --- 15t lifting force (lifting speed: 24m / min), and --- the drilling rig has --- propulsion and lifting force when working in deep hole.
4. The six cylinder turbocharged intercooled engine of Mingchang not only saves oil, but also provides sufficient power for the hydraulic system, --- the executive components of hydraulic pressure --- work.
5. The novel embedded slideway mechanism makes the power head more ---, ---, and greatly increases the sliding frame stroke (4m drill pipe can be installed), which is convenient for users to connect and unload drill pipe and casing.
6. Four independently operated large bore hydraulic jack cylinders, and the main engine can rise and fall automatically through hydraulic drive; Users can choose high outriggers according to their own needs, and the lifting height can reach 1.5m, which can simply complete loading and unloading.
7. The four leg cylinders can be controlled separately to facilitate the adjustment of the vertical angle between the borehole and the ground during drilling, and to ensure the stability of the whole machine during drilling.
8. The two-stage air filter intake design ensures the normal service life of diesel engine and air compressor under harsh construction conditions.
9. The main shaft of the power head realizes six gear rotation and stepless adjustable propulsion speed, which can meet the drilling needs of various complex strata such as soil layer and rock layer, so that the drill has a wide range of applicability.
11. This series of drilling rig adopts excavator crawler chassis, with strong off-road performance and convenient transfer.
12. The combined - -, which can be adjusted and replaced according to different types of drill pipes and impactors, is combined with the function of horizontal automatic transfer machine - --- accurate positioning and centering.
13. The newly designed drill pipe hoist makes the drill pipe loading and unloading fast and light.
14. (optional) it is equipped with arc welding generator to facilitate on-site welding maintenance and provide night construction lighting.
15. The independent module design can make the drilling rig installed on the truck and increase its mobility.
16. Our factory can provide φ 63.5, φ 76, φ 89, φ 102, φ 114 drill pipe (--- thick wall geological drilling pipe stm-r780, material: 36Mn2V, joint material: 35CrMo quenching and tempering treatment), the surface nitriding treatment can be carried out according to the user's requirements to greatly improve the wear resistance of the drill pipe.
