ABSTRACT:
An improved can crushing device designed to crush cans such as aluminum beverage containers for recycling purposes comprises a vertically reciprocating plunger 60, the faceplate 68 of which acts in conjunction with an elevated can platform 26, mounted on a primary column 10 to exert force at the top and bottom of the can 100 to effectuate the crushing process. A handlebar 62 attached at the top and a footbar 82 attached at the bottom of the plunger assembly 60 provides a means for the operator simultaneously to apply force from arm and leg muscles and body weight to crush the can. A suppressor 16 is built into the primary column to permit the operator to gain and maximize the use of momentum at the first and at the final stages of the crushing process and to absorb the abrupt reduction of downward movement at the last stage of the crushing process. A return spring 28 holds the device at its fully extended height except during the crushing process. The device also has anti-slip hand grips 64, and foot pads 86, and a resilient base surface 14 to maximize safety during its operation.
