ST 450 High Speed Water Well Drilling Equipment ,OEM Crawler Mounted Drilling Rig Machine
ST 450 Pneumatic Drilling Machine Introduction
The drilling rig is a light, efficient and multifunctional drilling equipment. It is mainly suitable for drilling wells, agricultural irrigation wells, geothermal air conditioning holes and other wells, especially for water intake projects in mountainous areas and rock strata. The efficiency is more than ten times higher than the traditional rotary drilling rig, and the economic benefits created for users are very considerable.

ST 450 Pneumatic Borewell Machine Advantages:
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
