Abstract: Provided is a crane jib transition structure, including a jib section, a transition section and a supporting structure. The jib section matches with the transition section, and they fixedly connect to each other. The upper end of the supporting structure fixedly connects to the upper end of the side of the jib section. The bottom end of the supporting structure fixedly connects to the bottom end of the corresponding side of the transition section. The middle part of the supporting structure fixedly connects to the connection point between the side of jib section and the corresponding side of transition section. Therefore, the crane jib transition structure can not only achieve the strength of a crane jib transition structure, but also achieve the strength and the overall stability of a crane jib, by using the supporting structure connecting to between the crane jib section and transition section.
