ABSTRACT:
A hydraulic power device usable to power a compactor ram of a waste compactor is provided. The hydraulic power device includes a pump assembly having first and second pumps for providing pressurized hydraulic fluid to at least one hydraulic cylinder and piston assembly associated with the compactor ram. A battery is provided for storing energy and for providing energy to the pump assembly. A solar panel converts solar energy and charges the battery. A pump control unit simultaneously operates the pumps when an operating pressure of the pump assembly is less than a predetermined threshold and operates only the first pump when the operating pressure of the pump assembly is greater than the predetermined threshold.
