Features of YGQZ-180 pneumatic drilling rig:
1. This drilling rig is an efficient and versatile down-the-hole drilling rig suitable for drilling water wells, irrigation wells, geothermal wells and various types of boreholes. It is especially suitable for water extraction projects in mountainous and rocky areas.
2. The drilling rig is capable of drilling holes in various strata (rock, clay, sand), with a maximum drilling diameter of up to 254 mm.
3. The drilling rig adopts a high-torque hydraulic motor power head and a brand diesel engine. The hydraulic control system is equipped with a large-diameter hydraulic cylinder. The diesel engine is equipped with a two-stage air filtration system for protection, and clean air provided by an air compressor can also be used.
4. The unique cam design and central control operating system make the machine easy to maintain and operate.
5. The drilling rig adopts an excavator crawler chassis with excellent off-road performance. It can also be installed on a truck to improve maneuverability.
6. The double gear rotation and feed speed enable the drilling rig to operate efficiently in soil and rock formations.
7. The system can be upgraded to dual system: 1) Pneumatic system with air compressor 2) Mud pump system with mud pump.
