Disposable Expansion Bag

The revolutionary aspect of the HYDRO-BAG equipment lies basically in the possibility of stripping blocks up to 1000 tons or more, without the need to prepare slots to house the jacks since the HYDRO-BAG has an original thickness of just 2 mm (0.08") and can be easily slipped into the wire saw cut.

It must be stressed that our equipment makes use only and exclusively of running water as a dilatation fluid, and not oil as for the hydraulic jacks, and therefore it is possible to say that HYDRO-BAG is environment-friendly too! Also from the safety point of view HYDRO-BAG offers the best guarantees: even in the case the cushion blows due to excessive inflating pressure, there will never be any deflagration due to the use of water, and not air, as inflating media. Last but not least, HYDRO-BAG doesn’t require any maintenance for the simple reason that after its use (often until it is broken) it can be

finally thrown on the scrap heap without regret.

As mentioned before, the thrust force obtainable by a single cushion can reach up to 1000 tons, but by coupling two or more cushions it is possible to obtain higher performances, if the cushions are side by side or combined together in packs.

To summarize, HYDRO-BAG is a simple, versatile and economical tool that has revolutionized quarry block stripping thanks to all the positive advantages as briefly described above.
