  • Patent number: 10906781
    Abstract: A pneumatic vertical transportation device comprises an expandable cylinder, a carriage rack, an air piping controller, and an air exhauster. The expandable cylinder includes a bellow body, with one end hanging carriage rack and the other end connected with a fixing plate. The expandable cylinder is connected with the air piping controller. While the carriage rack is rising, the air exhauster draws air from the bellow body through the air piping controller to gradually decrease pressure inside. Once pressure difference exceeds weight of the carriage rack, the carriage rack begins to rise. Volume of the expandable cylinder is reduced such that the lower disc of the expandable cylinder approaches top, and the expandable cylinder is maintained at low pressure state. While the carriage rack is descending, air is fed into the expandable cylinder through the air piping controller to gradually expand the bellow body, letting the carriage rack descend.
