St 450 Crawler Mounted Drill Rig Feautures:
1.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. It can simply complete loading and unloading, and completely solve the troubles of user equipment transfer.
2. 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 ensure the stability of the whole machine during drilling.
3. The two-stage air filter intake design ensures the normal service life of diesel engine and air compressor under harsh construction conditions.
4. 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 very wide range of applicability.
5. Centralized control hydraulic console for easy operation. Two sets of four pumps are designed to facilitate maintenance and reduce maintenance cost.
6. This series of drilling rig adopts excavator crawler chassis, with strong off-road performance and convenient transfer.
7. The newly designed drill pipe hoist makes the loading and unloading of drill pipe faster and lighter.
8. (optional) it is equipped with arc welding generator to facilitate on-site welding maintenance and provide night construction lighting
Characteristics of quick digging rig
1. The pneumatic water well drilling rig supplied by the manufacturer is equipped with hydraulic steel crawler, which has stronger off-road ability;
2. The rapid drilling machine is equipped with 4 high legs of hydraulic square pipe, which is convenient for on-site leveling and can save a lot of loading and unloading costs;
3. The left and right sides of the pneumatic drilling rig are equipped with drill pipe frame and foot pedal respectively, which makes the design more humanized;
4. The front end of the pneumatic drilling rig of construction machinery is equipped with auxiliary rod unloading oil cylinder, which is more convenient to loosen the drill pipe;
5. The water well adopts hydraulic universal drilling machine and crawler oil pump, which have more power to move the whole slope;
6. The percussive drilling equipment adopts manual automatic transmission and electric control shifter, which makes it easier to shift;
7. The pneumatic water well drilling rig adopts double oil pump for oil supply, and the hydraulic system uses shunt and confluence technology, so the power head rises and falls more rapidly;
8. The crawler drilling machine manufacturer is equipped with a folding auxiliary tower, which can lift two 3m / air drill pipe at a time.
