Second, the support strength is high, the stroke is large.
Third, the speed of the column and the column are greatly increased, and the support efficiency is improved, which solves the problem that the speed of the ordinary type of suspended column and the column is slow.
In fact, the working principle of the external injection type single hydraulic prop is very simple. Only the four steps of lifting column, initial support, bearing and returning column can complete the whole working process, and only the emulsion or neutral water can drive the DW external injection. The single hydraulic props work smoothly.
DW20-300/100X Acrow Props model definition: D means monomer, W means external injection type, 20 means the maximum height that the pillar can support, working resistance is 300KN, cylinder diameter is 100mm, generally from 0.6m to 3.5m Can be customized, you can call to explain your needs.
