Anti-down chain (hydraulic prop anti-down chain) manufacturer price hydraulic prop anti-down chain type hydraulic prop anti-down anti-down chain chain manufacturers in Shanxi, Jilin, Shaanxi anti-down chain manufacturers anti-down anti-down chain chain control total domestic coal production is help industry off the hook, "a punch." Total control, one vigorously eliminate backward production capacity, accelerate backward small coal mines closed exit. At present, the country has been identified and are being implemented closed 902 small coal mines this year, plans to close 800, anti-down chains strive to close before the end of 1000 small coal mines. At the same time, 300,000 tons of small coal mines are no longer building, for coal and gas outburst mine 90 million tons for the longer construction; secondly subtract dangerous coal production capacity, anti-down chain for coal and gas outburst and bump These two types of pressure to re-mine production capacity and subtract. Yuan, Ming also stressed during the coal loss, anti-down chain, some coal companies to the amount insured, low-cost promotion, but increasing the production capacity of anti-down chain model parameters: Size: 0.6 m hydraulic prop anti-down chain Specification 0.8 m Specifications 1.2 m in diameter chains: 6 mm hydraulic prop anti-down chain model to calculate the weight measurement units shall Gast Shandong Mining Equipment Manufacturing Co., Ltd. - Anti-down chain hydraulic pillar mining equipment manufacturers for many years engaged in the production and R & D, with the strength proven quality, welcome new and old friends to negotiate
