ABSTRACT:
Disclosed is a system and method for recovering energy from elevator apparatus and utilizing the recovered energy for useful purposes. This is accomplished by selectively coupling a hydraulic pump to the elevator drive when surplus energy is available thereby to pump and store pressurized fluid in accumulator devices. Such fluid, when above a predetermined pressure, is utilized to deactivate electrically driven units and drive the same by hydraulic motors supplied with fluid from the accumulator devices. Additional energy is recovered from heat present in the hydraulic fluid down-stream from the hydraulic pump and utilized beneficially.
