　　In 1986, LHS imported production technology of HYD200 hydraulic drifter from Secoma France, and manufactured the first Chinese hydraulic drifter.

　　Through 30 years of development, HYD series hydraulic drifters have gained the highest market share and the largest ownership in China, and LHS has accumulated strong technical strength at the same time. LHS made full use of technical advantage to manufacture spare parts of HYD series hydraulic drifters in batches, and meanwhile developed the high-quality spare parts of overseas and domestic hydraulic drifters and high-quality spare parts of drill rigs.
