The company said Monday afternoon that the shearer was sent to the Shaanxi Coal Group. It marks not just the 200th shearer in operation globally, but also the 90th in China.
“The most productive mining operations in the world choose the JOY 7LS because it mines at seam heights and production rates never before attained,” Joy officials said of the unit, which can extract more than 20 feet (6 meters) of coal in a single pass.
Joy Mining, a subsidiary of Joy Global, developed the world’s first all-electric multi-motor shearing machine in 1975.
In 1998, the company began production of the prototype 7LS shearer. Current models in the series are the 7LS1A, 7LS2A, 7LS3A, 7LS5, 7LS6C and 7LS7.
