Air jacks lifting bags help support air caster usages in many ways. By inflating the bag, air jacks push something away. Force can be created to push something away, to push it apart or to clamp. A lifting bag can be used to lift a heavy object, so that an air caster can be placed under it, for example.
It can also be used as an actuator, to press a wheel against the ground. You will also find these lifting bags in the Aerofilm roller mover. The lifting bags are installed under the legs of the transporter and then lift the roll off the floor when activated. Lifting bags have the ability to transfer large forces evenly. This relatively simple technology makes the lifting bag very reliable.
