“PNEUMATIC THREE AXIS MODERN TRAILER” is nothing but one of the Lifting systems in automobile at the time of emergency. In this Lifting system pneumatically operated one. Here the additional pneumatic cylinder and Control Valve is provided in the automobile itself. In this project, the Control Valve is used to activate/deactivate the Air input. The Valve is ‘ON’ at the time of emergency; the compressed air goes to the pneumatic cylinder. Then the compressed air passes through the tube, and then pushes the pneumatic cylinder, so that the Lifting is applied at the time of Valve in “ON” position (i.e.-Emergency time). The speed of the pneumatic cylinder is varied by using flow control valve. This is the way of controlling Lifting speed of the Trailer at the time of emergency. In our project, we have to apply this Pneumatic Modern Trailer Mechanism in Load Lifting Vehicles.          

Working Principle:   The Control Valve is fixed in near of the driving persons in the four-wheeler. The air tank contains the compressed air already filled. The Valve was ON at the time of emergency; the Control Valve was activated. The compressed air flow is controlled by the valve is called “FLOW CONTROL VALVE”. This air flow is already set. Then the compressed air goes to the pneumatic cylinders. The pneumatic cylinders piston moves forward at the time of compressed air inlet to the cylinder. The pneumatic cylinders move towards the Lifting arrangement.
