Drifter rods of 5.5 meters, 6.1 meters and 6.4 meters, drill bits of 45mm and 48mm, and anchoring bits of 51mm, 57mm, 64mm and 76mm of LHS, matching Atlas Boomer 353E, are well applied in large Chinese hydropower Projects like The three Gorges Dam, Gezhouba Dam, Xiluodu Dam, Guandi Hydropower Station, Shuibuya Hydropower Station, Jinping Hydropower Statin, etc. Drifter rods of LHS are the only domestic drilling tools which can replace imported drill rods. Many national large-scale enterprises of hydropower projects and tunnel construction like Sinohydro Group (Sinohydro Bureau 1, Sinohydro Bureau 4, Sinohydro Bureau 6, Sinohydro Bureau 7, Sinohydro Bureau 11, Sinohydro Bureau 13 and Sinohydro Bureau 14), Chinese Armed Police Hydropower Force, China Railway Construction Group (Bureau 13 and Bureau 18), etc. are important clients for drifting and tunneling tools of LHS.
