GY-300A 300M Coring Drilling Rig

1. auto chassis technology 2. standardized auto parts,easy operation and maintain 3. widely spindle speed 4. can Drill angle GY-300A Coring Drilling Rig Type:Coring drilling rig..........................................................................................................................................................GY-300A is a coring drilling rig for middle and shallow hole. It applies not only to alloy and diamond core drilling with different calibres but also can be used for geological prospecting works, drilling of fluid mineral in superficial layer and shot holes and ventilation holes drilling, drilling on hydrology, water wells and big calibres. It has been widely used on areas such as roade and railway construction, water resources and hydropower and architecture. Applications:1. Wire line diamond core drilling for exploration of metallic ferrous or nonmetallic solid deposits;2. Exploration engineering in the field of geology, metallurgy, coal mine,;3. Shallow oil and gas drilling, mine's gallery ventilation and water discharge tunneling;4. Foundation & Construction drilling for high-rise building, highway, railway, bridge, port, harbor work, piling, dam and tunnel.Main Features:1. Reasonable and compact in structure with the auto chassis technology;2. Easy to operate and maintain with standardized auto parts, such as gear-box, clutch and shifting mechanism;3. Wide combination of torque and spindle speed;4. Perfect stability with water brake for deep-hole drilling;5. Long feed stroke for higher efficiency;6. Pin type hydraulic chucks in high reliability for drill stem;7. Designed from the ground up as a compact, powerful, portable, light weight diamond core drilling rig for the remote areas.8. Stability for moving the car, fixed is simple, reliable, drilling into good stability9. With two gears reversal speed, easy to handle the hole accident.Technical Specifications
