The invention relates to the technical field of forklifts, in particular to a forklift portal frame. The defects that in the prior art, the lifting height is limited, the service life is short and the cargo stability is not high are overcome. The forklift portal frame comprises an outer portal frame body and an inner portal frame body, the inner portal frame body is arranged in the outer portal frame body, and second lifting oil cylinders are arranged on the two sides of the outer portal frame body. Second mounting grooves and pulleys are arranged on the two sides of the interior of the outer portal frame body, a movable frame is arranged at one end of the inner portal frame body through a lifting mechanism, the movable frame comprises two horizontal sleeves, a mounting hole, U-shaped connecting rods, a vertical rod and mounting plates, the sleeves are connected through the vertical rod, and the U-shaped connecting rods are inserted into the two sides of the sleeves separately. The mounting plates are arranged at the ends, close to the inner portal frame body, of the sleeves correspondingly, the width of the movable frame can be adjusted, the stability of cargoes is improved, the cargoes can be lifted to the high height through the two lifting oil cylinders, meanwhile, abrasion can be reduced, and the forklift portal frame is more durable.
本发明涉及叉车技术领域,尤其涉及一种叉车门架,解决现有技术中存在举升高度有限,使用寿命较短和货物稳定性不高的缺点,包括外门架和内门架,所述内门架设置在外门架的内部,所述外门架的两侧均设置有第二举升油缸,所述外门架内部的两侧均设置有第二安装槽和滑轮,所述内门架的一端通过升降机构设置有活动架,且活动架包括套管、安装孔、U型连杆、立杆和安装板,所述套管水平设置有两个,且套管之间通过立杆连接,所述U型连杆分别插接在套管的两侧,所述安装板分别设置在套管靠近内门架的一端,可以调节活动架的宽度,提高货物的稳定性,通过两个举升油缸,可以将货物举升至较高的高度,同时可以减少磨损,更加耐用。
