The main aim of a hydraulic can crushing machine is to smash an empty can into the smallest unit possible. Anyone who drinks a couple of sodas, cold drinks a week may never see the need to compact the cans, but others who are heavy drinkers may find these devices very helpful. Restaurants, bars, catering halls and recycling plants are places where a can crushing machine is pretty much a must. The main components used in this project are hydraulic cylinder with piston, Crank, piston and metallic body consisting of barring. In this project a crushing can is placed in the u shaped drum. The hydraulic cylinder is fitted with the piston. When the human applied force onto the moves the piston towards the drum and, the piston strike onto the can with large force which crushes the can.
