The Air lifting bag is part of the essential equipment dedicated to the extraction of blocks of marble, granite or any other stone. Indeed, its low thickness when empty allows it to be easily inserted in the sawing trenches. Several inflatable cushions are used simultaneously to spread the blocks of stone. They are maintained at a certain level by means of anchoring cables.
In addition, filled with air via a compressor, the quarry airbag spreads the rock evenly. This is followed by overlapping or shifting of the cushions until the stone blocks are tilted.
In the range of air lifting bags dedicated to the extraction of objects, you will also find the high pressure air lifting bag.
