Proof of Concept Fabrication of Multi-Axis Pneumatic Mechanism for Dumpers

At many building sites there isn’t sufficient space to manoeuvre the dumper in various directions to discharge the material to the front and side ways. In such situations, there is a growing demand of multi-axis articulated dumpers. This work deals with the fabrication of scale down prototype of three way dropping dumper wherein the dumper is operated using pneumatic tilting mechanism. There are three hydraulic cylinders which are operated by motor and gearbox to tilt the dumper body in all three directions. To maintain optimum efficiency of pneumatic system, the pressure drop between generation and consumption of compressed air is kept very low. Based on the initial prototype and tilting trials, it is demonstrated that this multi-axis system can be fully implemented in large scale. Further, the proposed pneumatic system can be automated with additional control system replacing the socket-pin arrangement to change the tilt directions with minimum human intervention.
