    LM series reverse rig
    Models of LM series reverse rigs: ZFY0.9 / 90 (LM-90), ZFY1.2 / 120 (LM-120), ZFY1.4 / 200 (LM-200), ZFY1.8 / 250 (LM-250) , ZFY1.4 / 300 (LM-300), ZFY2.0 / 400 (LM-400). LM series reverse well drilling rig is a kind of high-efficiency drilling equipment designed to change the backward technology of suspended tanks and manual construction widely used in the construction of underground mines in China.
  • LM-400 Powerful Reverse Drilling Rig (ZFY2.0 / 101.5 / 400)
    LM-400 Powerful Reverse Drilling Rig (ZFY2.0 / 101.5 / 400)
    2.1 ZFY2.0 / 101.5 / 400 (LM-400) Powerful Reverse Drilling Rig In order to change some of the shortcomings of the application of LM series reverse well drilling in deep coal and hydropower engineering, Beijing Research Institute of Scientific Research, Beijing General Research Institute of Science and Technology) has successfully developed the ZFY2.0 / 400 (LM-400) powerful back-drilling rig, which is a special fund project of the Ministry of Science and Technology. 2.1.1
  • LM-300 reverse well drilling rig (ZFY1.4 / 70/300)
    LM-300 reverse well drilling rig (ZFY1.4 / 70/300)
    LM-300 reverse well drilling rig is different from LM-400 in design emphasis. The latter is mainly for deep well construction under ground conditions. The former is an alternative to the LM-200 reverse well drilling rig commonly used in hydropower construction projects, which solves the LM-200 The shortcomings of the low-capacity reverse drilling rig are that it still retains the characteristics of small size, light weight, and convenient transportation and migration, and has stronger adaptability.
