The invention discloses a portal frame system and method for a lifting direct-drive electric forklift, solves the problem that in the prior art, due to the fact that the number of forklift lifting system structural parts is large, the working efficiency is low, and has the beneficial effects that the working efficiency is improved, and energy is saved. The pallet fork frame can be connected with a pallet fork, an extension section is arranged on the side portion of the pallet fork frame, one side of the extension section of the pallet fork frame is slidably connected with the portal, a guide wheel assembly is arranged on the inner side of the portal and can rotate relative to the portal, the other side of the extension section of the pallet fork frame can make contact with part of the guide wheel assembly, and the portal supports the direct-drive permanent magnet motor. The direct-drive permanent magnet motor is provided with annular teeth, the fork arm carrier is provided with straight tooth sections in the height direction of the fork arm carrier, and the straight tooth sections are provided with clamping teeth capable of being meshed with the annular teeth. A steel wire rope is wound around the direct-drive permanent magnet motor in the circumferential direction, and one end of the steel wire rope is connected with the balancing weight.

    本发明公开了一种升降直驱电动叉车用门架系统及方法,解决了现有技术中叉车起升系统结构件较多导致工作效率低的问题,具有提高工作效率、节约能源的有益效果,具体方案如下:一种升降直驱电动叉车用门架系统,包括门架和货叉架,货叉架可与货叉连接,货叉架的侧部设置延伸段,货叉架延伸段的一侧与门架可滑动连接,门架内侧设置导向轮组件,导向轮组件相对于门架可转动,货叉架延伸段的另一侧可与导向轮组件的部分接触,门架支撑直驱永磁电机,直驱永磁电机设置环向齿,货叉架沿着其高度方向分别直齿段,直齿段具有可与环向齿啮合的卡齿;直驱永磁电机的环向绕有钢丝绳,钢丝绳的一端与配重块连接。
