The invention relates to a multi-stage lifting forklift portal frame control system, a multi-stage lifting forklift portal frame comprises a first-stage portal frame and a second-stage portal frame, a forklift comprises a whole vehicle controller, and the multi-stage lifting forklift portal frame control system comprises a first induction part, a second induction part and a detection part; the first induction part and the second induction part are both installed on the second-stage portal frame, and the top end of the first induction part is higher than the top end of the second induction part. And the detection piece is mounted on the first-stage portal frame, is used for detecting the induction piece I and the induction piece II, and is in communication connection with the vehicle control unit. The control system starts to work when the pallet fork is lifted to exceed a certain height, the inclination speed of the portal frame is reduced, the walking speed of the whole truck is reduced, the speed of lifting the portal frame to the top is reduced, the shaking amount of the portal frame can be greatly reduced, and the safety performance of the whole truck is improved.

    本发明涉及一种多级起升叉车门架控制系统,所述多级起升叉车门架包括一级门架以及二级门架,所述叉车包括整车控制器,所述多级起升叉车门架控制系统包括感应件一、感应件二以及检测件;感应件一、感应件二均安装在二级门架上,感应件一的顶端高度高于感应件二的顶端高度;检测件安装在一级门架上,检测件用于检测感应件一、感应件二且检测件与所述整车控制器通信连接。本发明的控制系统在货叉起升超过一定高度时开始起作用,门架倾斜速度降低、整车行走速度降低及门架起升到顶的速度降低,此举措可大大降低门架晃动量,提升整车安全性能。
