Product Description Product DescriptionIntroduction of Outer Injection Single Hydraulic Prop DW31.5 Hydraulic Acrow PropsOuter Injection Single Hydraulic Prop DW31.5 Hydraulic Acrow Props increasingly widely used in the production of its traditional wooden pillars supporting metal friction compared with high recovery, supporting safe and reliable, working resistance constant, setting load is high, the use of flexible benefits. Outer single hydraulic prop can be used alone or in combination with metal hinged roof beams supporting the use, can be used in coal seam dip is less than 25. Stope roof gently inclined to pay, but also for mechanized coal face end support or temporary support available.zmwm10Product ParametersTechnology Parameters of Outer Injection Single Hydraulic Prop DW31.5 Hydraulic Acrow PropsTypeUnitDW35DW31.5DW28DW25DW22DW20DW18DW16DW14DW12DW10DW08DW06Max Heightmm35003150280025002200200018001600140012001000800600Min Heightmm27002350200017001440124011101005900792685578485 Working Strokemm800800800800800760690595500408315222145Net Weightkg82.876.4705855494743.639.936.33226.726.5Rated ResistancekN150200250300Rated Fluid PressureMpa19.125.531.838.2First Sustaining LoadkN118--157Pump Station PressureMpa15or20Column Lifting Speedmm/s≥60Column Descending Speedmm/s≥40Diameter of Oil Cylindermm100Base Areacm2113109Service Substance Coal 10 (M10)Emulsifier(or MDT10emulsifier)1-2% EmulsionDetailed PhotosImages of Outer Injection Single Hydraulic Prop DW31.5 Hydraulic Acrow Props
