- When the force needs to be equally devided on a surface area. Lifting bags are made of Rubber and follow the form of the surface area, against which the force is exercised.
- When huge forces are required. Force equals Area times Pressure (F = P x A). The maximum permissible air pressure for our lifting bags is, dependable on the type, between 5 Bar and 8 Bar. The Area of a lifting bag can be, theoretically, as big as you want.
- When you only need a small lifting stroke (lifting height). Lifting bags are not designed for large strokes.
