Hard Rock Core Drilling Rig Machine/Water Well Drilling Rig Gy-300

Product DescriptionGY-300A is a shallow/middle-hole core drill. It is applicable to not only the core drilling of small or big diameter with carbide and diamond bits, but also the engineering geological exploration and the construction engineering, hydropower engineering, highway/railway construction, port construction, etc. The outline is shown in Drawing 1. Features: 1. Rotation speeds of the drill rig are in a wide range (eight gears) and the speed distribution is rational;  2. It is characterized by low rotation speed and big torque and wide applicable range. It can be applicable to the low-speed big-diameter drilling besides the rapid-speed drilling; 3. It is of two-gear reverse speeds, with lower labor intensity and safe operation when dealing with the in-hole accident; 4. It has a large installed power and it is adapted to diesel engine or electric motor; 5. It features in advanced structure, rational layout, flexible and reliable operation, and is easy for repair and maintenance; 6. The drill rig is small in volume, light in weight, and easy to be disassembled and moved; 7. Feeding travel of the vertical shaft is 600mm, which benefits raising the drilling efficiency and reducing the possibility of drill pipe sticking; 8. Stable for moving, simple and reliable for fixing of drill rig, good stability for high-speed drilling, and a big distance between drill and hole; 9. Drillometer uses the oil-filling and anti-shock structure, with simple scale value, accurate indication and long service life. 10. The hydraulic plunger chuck is adopted, with reliable clamping operation and free from damaging the driving drill pipe;    Product Parameters S.N.ItemParameters1Bore Diameter93mm      150mm     200mm     300mmDrilling depth350m       280m      220m       120m2RotatorRotation speed of vertical shaftClockwise rotation:58, 101, 160, 221, 234, 406, 640, 885 r/minCounterclockwise rotation:46, 183 r/minMax. torque:3000 N*mFeeding travel of vertical shaft:600 mmMax. uplifting force of vertical shaft:60 kNUnit uplifting force:7.7 kN /MpaMax. feeding force of vertical shaft:45 kNUnit feeding force:5.7 kN /Mpa3HoistDiameter of drum:200 mmDiameter of wire rope:14 mmDrum capacity (five layers):45 mHoisting velocity (third layer):0.45, 0.785, 1.24, 1.71 m/sMax. hoisting force (single rope) :30 kN4Movable travel of drill:460 mm 5Distance between drill and hole-opening:260 mm6Oil gear pumpModel:CB-E25Nominal displacement:25 mL/rNominal speed:1500 r/minRated pressure:16 MpaMax. pressure:20 Mpa7Power machine Diesel engineElectric motorModel4L68Y180L-4Rated power24 kW22 kWRated speed1500 r/min1470 r/min8Drill dimension (L ×W ×H)2510×950×1820 mm9Net weight (excluding the power machine)1300kg  Detailed Photos   Packaging & ShippingFAQQ:Are you manufacturer?Yes, we are factory with more than 20 years of manufacturing experience.Q:What is your terms of payment?A: T/T 30% as deposit, and 70% before delivery.
