The invention belongs to the technical field of hoisting equipment, and particularly relates to a running cantilever crane which comprises a cart main beam, a cart end beam and a track, the lower surface of the cart end beam is fixedly connected with a cart frame, cart wheels installed on the lower surface of the cart frame walk on the track, guide mechanisms are arranged on the left side and the right side of the track and fixedly connected with the cart frame, and the cart frame is fixedly connected with the guide mechanisms. A lower stand column is detachably connected to the middle of the upper surface of the cart main beam, an upper stand column is detachably connected to the upper surface of the lower stand column, a cantilever is connected to the upper surface of the upper stand column through a swing mechanism and comprises a main cantilever body and an auxiliary cantilever body, the main cantilever body and the auxiliary cantilever body are detachably connected, and a fixing column is fixedly connected to the left side of the upper surface of the main cantilever body. The fixing column is connected with the main cantilever through a pull rod A and a pull rod B and is connected with the auxiliary cantilever through a pull rod C; the crane can move stably, the height of the stand column and the length of the cantilever are convenient to adjust, the use range of the crane is widened, the cantilever is high in stability, and safety accidents of cantilever breakage are avoided.

    本发明属于起重设备技术领域,具体涉及一种运行悬臂式起重机,包括大车主梁、大车端梁和轨道,大车端梁下表面固连有大车车架,大车车架下表面安装的大车车轮在轨道上行走,轨道左右两侧均设置有导向机构,导向机构与大车车架固连,大车主梁上表面中部可拆卸式连接有下立柱,下立柱上表面可拆卸式连接有上立柱,上立柱上表面通过回转机构连接有悬臂,悬臂包括主悬臂和副悬臂,主悬臂和副悬臂之间为可拆卸式连接,主悬臂上表面左侧固连有固定柱,固定柱通过拉杆A和拉杆B与主悬臂相连,固定柱通过拉杆C与副悬臂相连。该起重机可以平稳移动,便于调整立柱高度和悬臂长度,拓宽起重机的使用范围,悬臂稳固性强,避免出现悬臂断裂的安全事故。
