The invention relates to the field of forklift equipment, and provides a forklift outer door frame and a forklift, and the forklift outer door frame comprises a pair of door frame stand columns, a top connecting assembly, a bridge embracing assembly and a pair of inclined oil cylinder connecting assemblies. By means of the arrangement, the forklift outer portal frame forms a frame structure composed of a plurality of assembly modules, the top connecting assemblies and the bridge embracing assemblies are arranged on the tops and the bottoms of the portal frame stand columns, the stability of the whole frame structure is greatly enhanced, and the rigidity of the outer portal frame is improved. Meanwhile, the bridge embracing assembly is connected with the drive axle, and the inclined oil cylinder connecting assemblies on the two sides are connected with the inclined oil cylinders, so that force acting on the outer portal frame can be dispersed to the whole frame body, and the stress condition of the outer portal frame is effectively improved. Therefore, the transverse and longitudinal stability of the outer portal frame is greatly improved, and the failure conditions of fracture, cracking, deformation and the like of the outer portal frame are effectively reduced.
本发明涉及叉车设备领域,提供一种叉车外门架及叉车,包括:一对门架立柱、顶部连接组件、抱桥组件和一对倾斜油缸连接组件。如此设置,叉车外门架形成了由多个组件模块构成的框架结构,通过在门架立柱顶部和底部设置顶部连接组件和抱桥组件,极大地加强了整个框架结构的稳定性,提高了外门架的刚性。同时通过抱桥组件与驱动桥相连,且通过两侧倾斜油缸连接组件与倾斜油缸相连,可使作用于外门架上的力分散到整个框体,有效改善外门架的受力情况。从而大大提高了外门架的横向和纵向稳定性,有效减少外门架出现断裂、开裂、变形等失效情况。
