LQ-500 are cycle rig chisel rock Shi produced of rock powder, by Feng Shui mixed gas flush discharge hole outside, mixed gas is by row powder institutions by drill pipe Center injected impact device of, again by impact device cylinder body Shang of gas slot into hole end of. the products main applies Yu drill chisel wells, and agricultural irrigation well, and geothermal air conditioning hole and the other uses of well hole, especially applies Yu mountain and rock formation of take water engineering. efficiency than traditional of Rotary type rig high more than 10 times times, Creating very considerable economic benefit for customers. especially the soil air downhole hammer drilling difficult, hard rocks, gravel, gravel layer construction of Rotary drilling rig problems, able to work efficiently under various geological structures. Main technical parameters of LQ-500 circulation drill is as follows, the maximum hole depth: 500m, drilling diameter maximum 300mm 3000mm-6000mm drill pipe length, power stroke 7000mm, drill diameter 89mm/108mm/114mm, lift 35T, Rotary torque 12000NM, carrying mode: hydraulic crawler, walking speed 3000km/h, climbing 30 ° 3700mm*1900mm*2750mm, Weight 11000kg.
