The invention discloses a forklift portal and a forklift, and relates to the technical field of forklifts. The forklift truck particularly comprises a first-stage gantry, a second-stage gantry, a third-stage gantry, a fourth-stage gantry, a fifth-stage gantry and a fork arm carrier assembly which are sequentially connected. The first-stage portal frame, the second-stage portal frame, the third-stage portal frame, the fourth-stage portal frame and the fifth-stage portal frame are movably connected, and the five-stage portal frames are driven through the three telescopic pieces and the two transmission pieces. The stress of the lifting chain, the oil cylinder, the gantry of each stage and other structural parts in the five-stage gantry is reduced, and the bearing capacity of the gantry is improved.
本发明公开了一种叉车门架和叉车,涉及叉车技术领域。具体包括依次连接第一级门架、第二级门架、第三级门架、第四级门架、第五级门架以及货叉架组件;所述第一级门架、第二级门架、第三级门架、第四级门架、以及第五级门架之间均活动连接,通过三个伸缩件和两个传动件实现对五级门架进行驱动。降低五级门架中起升链条、油缸、以及各级门架等结构件的受力,提高门架的承载能力。
