DWX (suspended) single hydraulic prop is a new type of steel acrow props equipment developed by China Coal Research Institute. DWX Single Hydraulic Prop series products are technical products protected by national invention and utility model patents. On this basis, China coal machinery plant has developed a series of improved products, among which the improved high pillar series products have won the national patent.
Scope of Application
DWX series suspension hydraulic prop is a new type of single hydraulic prop with constant resistance for external liquid supply. It is the supporting equipment of high-grade mechanized general mining face and the end support equipment of comprehensive mining face. It is suitable for the roof support and the end roof support of coal mining face. Because of its large bearing capacity, strong anti eccentric load capacity, large working distance and wide range of use, it has the advantages of high-grade mechanical general mining face, high-grade mechanical general mining face and comprehensive mining face It can be used in thin coal seam, medium thick coal seam and thick coal seam. Its support height is 0.6-4.5m.
