This project is three axis pneumatic modern trailer works on the principles of pneumatic mechanism along with micro controllers. In this project the efficiency of dumping trailers will increase. The unloading of materials can be done to the three directions. This is very useful in the shipping industry. This project is advantageous for decreasing the man power and time for dumping trailers. The combination of pneumatics and micro controllers can be seen in this project. Pneumatic system is used in this project for automating the system. Automation is developing at a fast pace in manufacturing sectors and so this is a useful project for mechanical engineering students. This paper helps studying the principle of pneumatic system and its application includes use in shipping industry.
