This project demonstrates the design of a solar powered pneumatic jack that lifts loads efficiently with minimal human effort, suggesting improvements over conventional jacks.
Conventional jacks; screw and hydraulic jacks require some certain level of human effort and skill from the user, and the topography of some terrains make them difficult for use. The Pneumatic jack was fabricated to ease the use of handling and minor complications from handling the conventionally operated jack. Two basketballs are used as the bags for the pneumatic jack, and these basketballs are encased in a sheet metal casing. The metal casing protects the ball from puncturing, as rusted metal parts can be found beneath some cars. Using basketballs as the bags for the jack makes it cost effective for production. The air compressor is connected to a battery, charge controller and solar panel, and the hose is connected to the basketball valve. An air pressure of 0.241 N/mm2 on each basketball can lift a mid size sedan with an average weight of 1300kg off the ground to a height of 160mm in less than a minute. The fabricated pneumatic jack can be utilized in lifting loads in any topography with little or no human effort which is an advantage over the conventional jacks.
