A six-freedom-degree crane having a metamorphic function includes a hoisting jib mechanism, a jib telescoping mechanism and a metamorphism control mechanism. The hoisting jib mechanism is composed of a cargo boom and a suspension jib and enables the crane to complete grabbing, hoisting and unloading and such space operations of containers. The jib telescoping mechanism, which is in a parallel structure, is composed of three mechanical sub chains connected in series. The metamorphism control mechanism is formed by connection of linkage rods and is motion-synthesized with the hoisting jib mechanism. By means of the mechanical connection method, the crane is compact in structure and is high in reliability, so that the crane can effectively overcome the defects that hydraulic components of a hydraulic crane are high in processing precision requirement, high in maintaining cost and low in reliability degree and are liable to cause oil leakage. The six-freedom-degree crane is simple in control and is large in operating space, can be widely applied in grabbing, hoisting and unloading and such complex operations of the containers.
