Design & Fabrication of Pneumatic Weight Lifting Trolley With 3 Way Movement

The material handling vehicles usually take more time to adjust its position, and unload at the exact location. The system now available is to unload material on back side. As considering the mines space available is less due to which unloading raw material on left or right side is not possible to take this as a problem multi directional trolley is the solution.This paper explain the design and fabricate a trolley with 3 directional unloading and lifting arrangement. This mechanism is proposed to make the unloading easier in multi direction,only by providing 3 directional movement to the trolley rather than the vehicle in order to make the work more economic and efficient. The dumping will be done by using pneumatic cylinder, the compressed air will pass from the compressor to the direction control valve which will control the compressed air according to the required action (forward or backward stroke).
