The invention discloses a folding crane. The folding crane comprises an unfolding drive mechanism, a frame body mechanism and a suspended loading mechanism mounted on the frame body mechanism. The frame body mechanism comprises first frame bodies, second frame bodies and third frame bodies. The unfolding drive mechanism comprises an unfolding electric winch, an unfolding steel wire rope and an unfolding guide wheel. When the crane is unfolded, plane structures of the two first frame bodies are attached, slope structures of the first frame bodies are attached to slope structures of the second frame bodies, the first frame bodies and the second frame bodies are in a vertical state, and plane structures of the third frame bodies are attached to the plane structures of the second frame bodies.Objects are subjected to suspended loading through the suspended loading mechanism, under the effect of the unfolding drive mechanism, the automatic unfolding function after the whole crane is foldedis achieved, unfolding is convenient, meanwhile, under the effect of a closing drive mechanism, automatic folding and storing of the whole crane are achieved, the occupied space is small, the crane can be conveniently stored, transported, moved and transferred, and the corresponding cost is reduced.

    本发明公开了一种折叠起重机,包括展开驱动机构、架体机构和安装于所述架体机构上的吊载机构;所述架体机构包括第一架体、第二架体和第三架体,所述展开驱动机构包括展开电动卷扬机、展开钢丝绳、展开导向轮;起重机展开时,两所述第一架体的平面结构相贴合,所述第一架体的斜面结构与第二架体的斜面结构相贴合,且第一架体与第二架体呈垂直状态,第三架体的平面结构与第二架体的平面结构相贴合。本发明通过吊载机构实现物体吊载,在展开驱动机构作用下,实现整个起重机折叠后的自动展开功能,展开方便,同时在闭合驱动机构作用下,实现整个起重机的自动折叠收纳,占用空间小,方便起重机存储、运输、移动、转场等,节省相应成本。
