Medium- and High-Pressure Constant-Deceleration Hydraulic Station


  In 2010, Jinmin Group successfully developed a test bench for constant-deceleration braking systems and also successfully prototyped a medium- to high-pressure constant-deceleration hydraulic station. This equipment was supplied as an integral component of the JK‑3×2.2 mine hoist and shipped to Linfen Jinniu Coal Mine Investment Co., Ltd., part of Shanxi Jincheng Anthracite Mining Group. Following installation and commissioning at the mine site, the constant-deceleration hydraulic station has been operating normally.
