Abstract
A method and a system for recovering and utilizing crane operating energy and a crane includes converting by a first hydraulic power means hydraulic energy generated by a hydraulic actuator into mechanical energy of a transmission shaft; driving, by the transmission shaft, a second hydraulic power means to rotate so as to convert the mechanical energy of the transmission shaft into mechanical energy of the second hydraulic power means; filling, by the second hydraulic power means, pressurized oil into an accumulator so as to convert the mechanical energy of the second hydraulic power means into hydraulic energy for storage.
