DWX (suspension type) hydraulic prop is a new type of hydraulic block with constant resistance and constant resistance. It is supporting equipment for high-grade mechanized mining face, as well as end support equipment in fully mechanized face. It is generally applicable to roof support and end support in coal mining face. As the product has the advantages of large carrying capacity, strong anti deviation capacity, large working range and wide application range, the utility model can be widely used in the thin coal seam, the medium thick coal seam and the thick coal seam work face.

The product has the following characteristics:

■The plunger suspension technology principle, pillar of the levitation force to work resistance 4/5, column capacity is only 1/5, thus greatly improving the stability and security of the pillar, improve the supporting pillar height, bearing capacity and anti bias load.

■Suspension type hydraulic prop no arc weld, no leakage, visual inspection, support once the leak can be replaced at any time and the support pillar, more safety, avoid the pillar caused by internal leakage of the empty top pillar and tedious work.

■The suspension hydraulic prop three valves are designed on the handle off the hand. When the liquid is injected, the three valve is not raised with the movable column, and the working stroke of the support is increased.

■The sealing points of suspension hydraulic prop are sealed and tightened, and the replacement of the sealing parts is very convenient. The assembly and disassembly are simple, and the damaged parts only need to be replaced.

■The movable column adopts the intermediate frequency heat treatment processing technology, and improves the products anti explosion, mechanical damage and bending resistance, reduces the maintenance quantity of the prop and improves the safety of the product.
