The invention provides a rotary gantry crane, comprising: a gantry, the gantry comprising a gantry assembly and a cylindrical beam, the cylindrical beam being vertically arranged on the gantry assembly; and the hoisting assembly is rotatably arranged at the top of the cylindrical beam. According to the rotary gantry crane disclosed by the embodiment of the invention, a traditional gantry is changed into a cylinder type from an eight-supporting-rod type, a lower rotary column structure is cancelled, the stress and bending resistance is improved while the structure is light, the durability of the crane is enhanced, and the rotary gantry crane is convenient to mount, dismount and maintain and low in cost.
本发明提供一种回转式门座起重机,包括:门座,所述门座包括门架组件和圆筒梁,所述圆筒梁竖直设于所述门架组件上;起重组件,所述起重组件可回转地设于所述圆筒梁的顶部。根据本发明实施例的回转式门座起重机,将传统的门架由八撑杆型式改为圆筒体型式,取消了下转柱结构,结构轻型化的同时也提高了抗受压受弯能力,增强了起重机的耐用性,便于安装拆卸维护,且成本低。
