Introduction of DW45-250/110X Underground Mining Hydraulic Acrow Prop

DWX type hydraulic acrow prop adopts the plunger suspension technology principle, so that the hydraulic suspension force acts directly on the top cover through the inner cavity of the pillar living column. The hydraulic levitation force shares about four-fifths of the working resistance of the pillar, so that the axial force of the live column is only one-fifth of the working resistance, which improves the stability and safety of the pillar and greatly improves the pillar. Support height and carrying capacity. The pillar products using the principle of piston technology cannot fully utilize the hydraulic suspension force to share the working resistance of the column. The column is subjected to all the working resistance, so that the column is often crushed and damaged, resulting in an accident.
