摘要
Disclosed are a method and a system for recovering and utilizing duty energy of a crane and a crane. The method for recovering and utilizing duty energy of a crane comprises: a first hydraulic power device (2) converts the hydraulic pressure energy produced by a hydraulic actuating mechanism (101) into the mechanical energy of a transmission shaft (102); the transmission shaft (102) drives a second hydraulic power device (4) to rotate and converts the mechanical energy of the transmission shaft (102) into the mechanical energy of the second hydraulic power device (4); the second hydraulic power device (4) fills an energy storage (5) with a pressure oil and stores the hydraulic energy converted from mechanical energy of the second hydraulic power device (4). The method can effectively recycle gravitational potential energy during the fall of weight in the lifting and luffing duty of the crane and the recycled energy can be re used to drive hoisting and luffing which reduces the fuel consumption of lifting duty saves energy and reduces emissions.
