This type of drill rig can take the place of imported products and be applied in the fields of geology, metallurgy, coal mines, petroleum, natural gas and underground water exploration. Main Specifications 1. Equipped with steel track, double-speed driving device for the chain of the oil tank, and with power head, hoisters, mud pump and oil tanks controlled by hydraulic devices, the drill rig features flexible in operation, simple in structure and convenient for maintenance. 2. By using the power head driven by double-motor driving technology, it is reliable in power transmission, stable in start and stoppage. 3. With long-range feeding system, the feed travel reaches 3200 mm, which increases the drilling efficiency and decreases the probability of in-hole malfunctions. 4. By using the structure of folding mast, the operation angle can be easily adjusted. The drill rig can drill holes of 45-90? It is convenient to mount and transport. 5. With 132KW power unit and sensitive 2-point-control simulated load system, the drill rig is high in efficiency and low in energy consumption. 6. It has high hoisting force. The single-wire hoisting force of the main hoister is 77000 kg and supplementary hoister 1200 kg. 7. The hydraulic chuck adopts 5-point holding device, which holds the drill rod more powerfully. 8. For the mud pump is provided with enough obligating power, the drill rig can meet the needs of percussion drilling. 9. With centralized-control panel, the control operation of power unit as well as hydraulic unit is more stable. 10. With reliable steel track, it is convenient to mount and economical for transport. 11. The design of the drill rig is reliable and can adapt to poor operation surroundings.
