The invention provides a circular track cantilever crane which comprises a pair of running vehicles, and a first circular track for hanging the pair of running vehicles. The pair of running vehicles comprise two main bodies; at least one pair of running pulleys matched with the first circular track, and a drive mechanism for driving the pair of running pulleys to move are arranged on each main body; the bottom parts of the two main bodies are connected with a cantilever beam through hinged shafts; a sliding chain block running along the cantilever beam is arranged on the cantilever beam; the two main bodies are connected through a connecting beam; and an included angle adaptive to the radian of the first annular track is formed between the two main bodies. The circular track cantilever crane further comprises an overturn-preventing mechanism. According to the circular track cantilever crane provided by the invention, a linear type hoisting range is expanded to a circular hoisting range, so that the running range of the crane is increased, the running position adjustment range is provided, and the use efficiency is improved.

    本发明提供一种环形轨道悬臂式起重机,其包括一对运行车,一第一环形轨道,第一环形轨道用于悬挂该对运行车;该对运行车包括:两个本体、每个所述本体上均设有至少一对用于与该第一环形轨道配合的运行滑轮;以及用于驱动对运行滑轮运动的驱动机构;所述两个本体的底部均通过一铰轴与一悬臂梁连接,在悬臂梁上设有一沿悬臂梁运行的滑链葫芦;其中,所述两本体之间通过一连接梁连接,且所述两本体之间形成一与第一环形轨道的弧度适配的夹角;环形轨道悬臂式起重机还包括一防倾覆机构。本发明的环形轨道悬臂式起重机将直线型的起重范围扩展成一环形的起重范围,不但增加了起重机的运行范围提供了运行位置调整的范围,提高了使用效率。
