About DW DW hydraulic prop hydraulic prop is constant resistive pillar, which can cooperate with a variety of roof beams, columns can also decide to use. Mechanized mining for coal or artillery general mining face plate with supporting items, are also available for mechanized coal face end support or other temporary support to use. DW hydraulic prop metal hinged roof beams fit in time for the general mechanization of coal mining face gun and mechanized mining face end or interim payments roof used for coal mining face angle is less than 25 °, to take certain measures, also can be used to dip 25 ° --35 ° stope. This series of good single hydraulic pillar stability, outstanding technical performance advantages, the single support mine atmining face height by 2.5 meters to 3.5 meters and 3.5 meters below the coal seam can be taken to achieve a full-time high, while To provide end seam thickness and advance support for the 4.5 m below Face. DW hydraulic prop Features 1, large working stroke, especially for underground roof work surface height variations. 2, using the hole sealed pillars in the underground resistance to bump, using a wide surface. 3, never broken. Using friction welding, the weld does not break. 4, pillar using a new sealing device, remove the leaking point DZ type strut piston and plunger between safety and reliability. 5, the level of support. 6, high-strength, bend.
