Quarrying Use Stone Block Push Down Tools Steel Hydro Bags

Hydro-bag, also called a Water Bag, is a dialating hydraulic cushion that consists of two sheets of high tensile steel that expands, under the pressure of water pumped at 30-40 bar, permitting a maximum dilatation of 25-30 cm (approx 1′) and a thrust force up to 1000 tons*.

The Hydro-bag is environment-friendly since only running water (not oil as in hydraulic jacks) is the dilatation fluid. It is safe; even if Hydro-bag’s cushion blows due to excessive inflating pressure, there is no deflagration because water, not air, is the inflating media. The Hydro-bag doesn’t require any maintenance; throw it away after using (until it is broken).

*For one cushion, the thrust force obtainable can reach up to 1000 tons. Couple two or more cushions to obtain higher performances; side by side or combined together in packs.

Equipment required for Hydro-bag consists of:

1. Electric pump to create the pressure for the cushions;

2. Safety valves and distribution valves;

3. Pipes, cocks and inlet filters;

4. Quick couplings;

5. Hydro Bag (also known as waterbag) cushions.
