What brand of rotary drilling rig quality is better? How much? How long is it back?
At present, the domestic rotary drilling rig manufacturers are also many, good and bad, good and bad. Large enterprises such as 31, CSR, China United, Xugong, mountains and rivers, Jintai and so on, there are many small enterprises, not one by one examples. We recommend rotary drilling rig for 31 and csr.
From the quality, Bauer, but, force big foreign soil is definitely one of the king, started early, mature technology, excellent quality, engineering absolute peace of mind. The only drawback is that compared to the domestic situation, the price is too high, almost the same level of domestic drilling rig 1 - 2 times. Although the quality of the excellent, but considering the initial investment, back to the time and other factors, most customers are discouraged. The same model, Bao goose can sell 700W-800W, but domestic brands only need 400W or so, although the quality is higher, but the price is difficult to accept. Therefore, it is recommended that you do not recommend investing in these brands unless you have substantial funds.
Rotary drilling rig is still a gap between domestic brands and foreign brands.
