The invention provides a forklift portal system. The forklift portal system comprises an outer portal; an inner portal is arranged in the outer portal; the outer portal and the inner portal are connected through a hoisting cylinder; a fork arm carrier is arranged on the inner portal in a sleeving mode; sliding blocks are arranged at the upper end of the outer portal, the lower end of the inner portal and the fork arm carrier; when the inner portal ascends along the outer portal, the sliding block on the outer portal makes contact with a web face and a rib plate face of the inner portal, the sliding block on the inner portal makes contact with a web face and a vertical column face of the outer portal, and the sliding block on the fork arm carrier makes contact with the web face and a vertical column face of the inner portal. By the adoption of sliding friction, a direct face-to-face contact lifting mode replaces a traditional point-surface contact lifting mode, so that abrasion resistance in the use process is achieved, installation is simple, assembly time of workers is shortened, and the production efficiency is improved; meanwhile, the portals can ascend stably, and the service lives of the portals are greatly prolonged.
