Introduction of DW20-350/110X Suspension Single Hydraulic Acrow Props

1.Large work schedule and low cost of safety management. Each specification can replace the traditional piston-type single-pillar 2-4 specifications, reducing the labor intensity of the workers and the extra spare capacity of the pillars.

2.High support strength and good safety and stability. The pillars have no bearing welds, and the pillars adopt the suspension technology principle, and the suspension force generated by the high pressure liquid directly acts on the top cover end.

3.Leak is easy to find, safe and reliable. Adopting the principle of seal compensation and sealing tension technology, the larger the pressure of the top plate, the tighter the sealing surface fits, and the more difficult it is to leak.
