The unique feature of Sava lifting bags is the combination of triple-chamber and single-chamber bags.
There are 5 standard models capable of lifting up to 300 cm high. A two layer rubber-coated fabric connected with thousands of mono-filament fibers assures excellent stability of the lift bags in all directions. This results in greater safety even with the largest size bags which are capable of lifting upwards of 46 metric tons.
