ABSTRACT
Automobiles are now becoming the most essential part of our day-to-day life. This is the golden age for automobile companies, since they are attaining their peak selling rates in this 21st century. However with the increased production they are facing lots of problems like traffic, fuel efficiency, blends, exhaust gas analysis, etc., Among them providing a proper and efficient weight lifter system in an automobile is a major issue for them. With increased load carrying requirements equipping the lifting system with more facilities is their major objective. In addition to that efficiency of the hydraulic lifting system gets reduced due to the self weight of the tipper truck. The system will have to lift the load along with the trailer and it is a major limitation in this equipment.
In this project, we made a simple and economical solution to the above mentioned problem. We used pneumatic spring as our major capital and fabricated an equipment which can be attached to any automobile that it assists the conventional hydraulic system by means of the compressed air. The attachment is to be connected with the base of the trailer. Due to cost factors a small prototype of this project was done. Here we did a model with two metal frames hinged with each other. Two pneumatic springs are connected on either side of the frame with nuts and bolts. Self weight of the upper frame compresses the spring, then it can be easily lifted with less force due to the application of the compressed air inside the spring.
