Introduction of China Supply DW38-250/110X Type Mining Acrow Props

1.Light weight
According to the different specifications of the pillars, the weight of the whole column is reduced by more than 15-30% compared with the previous pillars. However, its work resistance, working stroke and stability safety factor are higher than the aluminum alloy pillar.
2.High reliability
There is no longer a circular arc weld on the acrow prop that is difficult to guarantee, and the strength and reliability of the column are also improved. It avoids the hidden dangers such as roof fall caused by the fracture of the weld and ensures the safety of the staff.
3.Strong anti-offset capacity and greater stability
Acrow prop adopts the principle of plunger suspension technology, 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 is shared by about four-fifths of the working resistance of the pillar, so that the axial force of the living column is only one-fifth of the working resistance.
