After the airbag is fully lifted, an air film will be generated between it and the ground, which can greatly reduce frictional resistance and achieve a state of suspended operation. There is almost no friction with the ground and the resistance is very small. Therefore, only a small force is required to complete the transportation, installation and positioning of the equipment.
