DWB series portable hydraulic single prop is constant-resistance prop with hydraulic oil supply outside.as the pioneer of designing and manufacturing this equipment in China,we adopt many advanced technology and special nonmetallic material,making it portable,erosion resisted and easy to operate.its weight is only 40% of steel prop with same height,it reduces operater’s labor intensity and improve working efficiency.
The prop is used for temporary roof supporting in the lane,especially when carrying out lane maintenance and road heading. It adopts emulsion or static pressure water as driven medium.all the key parts(movable prop,cylinder,pedestal,rest spring,etc.)adopt advanced erosion resisted technology ,and can resist acid and alkali corrasion,so it suits for various working environment.
