The invention relates to the technical field of road traffic, in particular to a directional cantilever crane capable of improving bridge construction safety, which comprises a vertical support frame, a first cantilever, a second cantilever, a guide wheel group, a hoisting mechanism, a directional base plate and a telescopic arm, and the vertical support frame, the first cantilever, the second cantilever and the directional base plate form a spatial quadrilateral structure. The first cantilever and the second cantilever are driven by the rotary driving mechanism to rotate, and the end face of the directional base plate is always parallel to the end face of the vertical supporting frame in the rotating process, so that the telescopic arm and a load borne below the telescopic arm keep a fixed orientation in the rotating process; and in the process of stacking, loading and shifting loads, operation is more convenient and faster, and safety is higher.
本发明涉及道路交通技术领域,具体为一种提高桥梁建造安全的定朝向悬臂起重机,包括竖向支撑架、第一悬臂、第二悬臂、导轮组、卷扬机构、定向基板和伸缩臂,竖向支撑架、第一悬臂、第二悬臂和定向基板构成空间四边形结构,通过旋转驱动机构驱动第一悬臂和第二悬臂进行转动,并在上述的转动的过程中实现定向基板的端面始终与竖向支撑架的端面平行,进而实现伸缩臂以及其下方承载的载荷在所述的转动的过程中保持固定的朝向,能够在将载荷码垛、装载、移位的过程中,操作更加便捷且安全性更高。
