DW hydraulic prop mining hydraulic prop DW35-150 / 100 outer single hydraulic prop DW31.5-200 / 100 outer single hydraulic prop DW28-250 / 100 outer single hydraulic prop DW25-250 / 100 outer single hydraulic prop DW22-300 / 100 outer single hydraulic prop DW20-300 / 100 outer single hydraulic prop DW18-300 / 100 outer single hydraulic prop DW16-300 / 100 outer single hydraulic Pillar Product Details: DW hydraulic prop About DW hydraulic prop is constant resistance type pillar, which can cooperate with a variety of roof beams, columns can also decide to use. Mechanized mining for coal in general or blasting mining face support key board are also available for mechanized coal face end support or other temporary support to use. DW35-150 / 100 outer single hydraulic prop country back into the tide of phone-renewed, following the nationalization of coal in Shanxi, Shandong and Japanese steel nationalization, it was rumored Inner Mongolia coal nationalization, DW35-150 / 100 outer single hydraulic Coal pillars of the country back into the news. As of October 24, the integration of coal resources and coal mining enterprises in Shanxi mergers and acquisitions work progress smoothly social concern. City Coal Mine in Shanxi 11 reorganization and integration of all the validation program has been completed, DW35-150 / 100 outer single hydraulic prop reorganization and integration of coal mining enterprises reached 97.9% agreement rate. 1053 mine DW35-150 / 100 outer single hydraulic prop retained after the consolidation, the state-owned mining operation accounted for 19%, private mining operation accounted for 28%, DW35-150 / 100 outer single hydraulic prop to the main shareholding form DW35-150 / 100 outer single hydraulic prop mixed ownership enterprises accounted for 53% of the mining operation. DW35-150 / 100 outer single hydraulic prop DW31.5-200 / 100 outer single hydraulic prop DW28-250 / 100 outer single hydraulic prop DW25-250 / 100 outer single hydraulic prop DW22-300 / 100 outer single hydraulic prop DW20-300 / 100 hydraulic prop DW18-300 / 100 hydraulic prop DW16-300 / 100 hydraulic prop DW14-300 / 100 hydraulic prop DW12-300 / 100 monomer hydraulic prop DW10-300 / 100 hydraulic prop DW08-300 / 100 hydraulic prop DW06-300 / 100 hydraulic prop DW hydraulic prop and metal with hinged roof beams for general mechanized coal mining face and gun mechanized mining face end or roof with a temporary payment for Coal Seam angle is less than 25 °, and when to take certain measures, can be used for dip 25 ° --35 ° stope. This series of good single hydraulic pillar stability, outstanding technical performance advantages, the height of the single support coal mining face in high-grade Pu from 2.5 meters to 3.5 meters, 3.5 meters below the seam can be taken to achieve full-time high, while To provide end seam thickness and advance support for 4.5 m below Face. DW hydraulic prop Features a working stroke large, especially for large underground roof height variation Face. 2, using the hole sealed pillar in the underground resistance to bump, using a wide surface. 3, never broken. Using friction welding, the weld is not broken. Four pillars with a new seal, remove the leaking point DZ-type pillar between the piston and plunger, safe and reliable. 5, the level of support. 6, high strength, bend.
