ABSTRACT:
A can crusher for environmental protection is generally composed of a hydraulic pump to drive a piston, upwardly or downwardly. When the piston is driven downwardly, a plate is driven downwardly to crush a can. A groove is formed at an inner bottom portion to drain any residues left in the can to a collecting pan.
