Air casters reduce the friction to a thousandth of the normal situation. This allows you to move 1.000 kg with 1 kg of force. In this floating state you can therefore easily move and position large weights such as turbines and windmill blades. Even in tight spaces, where you cannot get through, for example due to the turning circle of the wheels, air casters provide a solution. The load pressure to the floor is much less than other options, distributing weight over the surface of the caster, eliminating point or line load, regardless of whether it is 1.000 kg or 5.000.000 kg, the floor pressure will be below 60 pounds per square inch.
