STQ-220 High Speed 200m Pneumatic Borewell Machine
Overview of STQ-220 Pneumatic Drilling Rig
STQ-220 Pneumatic Drilling Rig is a light, efficient and multi-functional drilling equipment. It is mainly suitable for industrial and civil drilling and geothermal drilling. It has the advantages of compact structure, fast footage, flexible movement and wide application area. It is especially suitable for water intake in mountainous area and rock stratum.
Advantages of STQ-220 Pneumatic Drilling Rig:
- STQ-220 Pneumatic Drilling Rig can be used for drilling in different formations, and the drilling diameter can reach 245-294mm. The drilling rig adopts new hydraulic technology, supporting large torque hydraulic motor rotation and large bore hydraulic cylinder propulsion. The famous multi cylinder engine provides power for the hydraulic system. The two-stage air filter and air inlet design of air compressor extend the service life of diesel engine. The unique pump unit design is convenient for maintenance and reduces the maintenance cost. Centralized control of the hydraulic console, easy to operate
- STQ-220 Pneumatic Drilling Rig adopts crawler chassis of excavator with strong cross-country performance. Independent modular design allows the rig to be mounted on a truck to increase its mobility. The two-stage rotation and propulsion speed can meet the different drilling requirements in soil and rock strata. Combined positioner can be adjusted and replaced according to different types of drill pipe and impactor to ensure accurate and reliable positioning and centering. The hoisting mechanism is convenient for the hoisting of drill pipe and impactor and reduces the labor intensity.
