A power drive for a passenger and/or cargo elevator—or any conveyance-using stored high pressure compressed air as a primary source, producing high pressure hydraulic fluid energy to move a servo-controlled hydraulic motor, mechanically connected to the hoisting mechanism of the elevator, is disclosed. The electric power driving the air compressor is not affected by the load of the elevator (e.g. number of passengers). The electric current is consumed to charge a high pressure air tank. The compressor is operated only when the elevator is in in a parked position, thus electric power consumption level is by no means correlated to the operational mode of the elevator motion.
