Abstract

Fluid power plays a crucial task in today’s industry as this meadow deals with the generation, control and transmission of pressurised fluids. The development of a portable pneumatic jacking system is one portion of fluid power which applies air as a fluid medium and used for lifting the load around 1000 kg. The main objective of this project is to develop and produce a device which can help people to utilise it as a cylinder of jacking system. The investigation has been conducted by taking the advantages of air compared to liquid which clearly defined that air is light and not messy. Other than that, the studies have also been done by applying the relationships between the force imposed to the cylinder, the working pressure of compressed air and the size of the tube. The project done was based on several methodologies which were the design concept, materials used, assembling processes, bill of materials and last but not least the analysis and calculation. After the completion of producing the product, some field tests have been conducted which were on the human weigh, on the pneumatic table and on the Kancil car; the maximum operating pressure of 3.4474 bars could be used to lift the weigh of 255.9156 kg with no stroke measured.By comparing the analyses made with the results obtained, it is clearly seen that the use of 3.4474 bars pressure could only be used to lift the weigh below than 255.9156 kg. Therefore, the tyres are not to be recommended to lift the weigh of car, otherwise the use of specialised material such as air lifting bag is suggested since the bag has been specialised for the use of high pressure.
