The invention relates to the technical field of cranes, in particular to a high-stability portal crane which comprises a guide rail, a portal frame, a cross beam, a travelling crane, a cable, a connecting block, a supporting disc, a rotating disc and the like. A gantry is slidably mounted on the guide rails, a cross beam is fixedly mounted on the gantry, a traveling crane is slidably mounted on the cross beam, two cables are connected to the traveling crane, a connecting block is fixedly connected to the lower ends of the two cables, a supporting disc is fixedly connected to the lower end of the connecting block, and a rotating disc is rotationally connected to the supporting disc. And when goods are lifted to the set height, rotation of the hook is automatically limited, the situation that the goods drive the hook to rotate when the gravity center rises due to the fact that high-altitude wind power is large is prevented, then the situation that the goods possibly swing is reduced, and the stability during goods lifting is improved.

    本发明涉及起重机技术领域,尤其涉及一种高稳定性的门式起重机,包括有导轨、门架、横梁、行车、缆绳、衔接块、支撑盘、转动盘等;导轨上滑动安装有门架,门架上固定安装有横梁,横梁上滑动安装有行车,行车上连接有两根缆绳,两个缆绳下端固接有衔接块,衔接块下端固接有支撑盘,支撑盘上转动连接有转动盘。在货物上升到设定高度时自动限制挂钩转动,防止高空风力较大、重心升高时货物会带动挂钩发生旋转,进而降低了货物可能会发生摆动的情况,提高了吊运货物时的稳定性。
