Mining Individual hydraulic prop Introduction:
DW series individual hydraulic props can be used individually or with metal articulated roof beam.
DW type (suspension) is a hydraulic prop (outside the Note style) single support equipment, the pillar series total of fifteen kinds of specifications, respectively, for mining height of 0.63 to 4.5 m coal seam, each angle is less 25 degrees of gently inclined coal face, if take certain safety measures, the scope can be extended to 25 degrees to 45 degrees angle of mining.
