The invention relates to the technical field of forklifts, and particularly discloses an electric lifting forklift gantry with a counterweight, which comprises a forklift body and a fork head, and an electric driving unit is mounted on the forklift body; an outer door frame is fixedly mounted on the vehicle body, an inner door frame can roll up and down through a roller and a first roller path in the outer door frame, and a fork head can roll up and down through a roller and a second roller path of the inner door frame; and the electric driving unit is connected with the lifting unit. The movable balance weight is arranged in the lifting device, when the inner portal and the fork head ascend, the movable balance weight descends, the potential energy of the high position of the movable balance weight is converted into the kinetic energy of lifting of the fork head and finally converted into the potential energy of the fork head at the high position, electric energy output of the motor is reduced, energy is saved, and the energy needed by ascending of the movable balance weight comes from descending of the fork head; extra energy input is avoided, energy input is reduced, and meanwhile, the output power needed in the process that the motor drives the fork head to move upwards is correspondingly reduced due to the arrangement of the movable balance weight.
本发明涉及叉车技术领域,具体公开了一种带配重电动起升叉车门架,包括车身、叉头,所述车身上安装有电力驱动单元;车身上固定安装有外门架,内门架通过滚轮与外门架内的第一滚道可上下滚动,叉头通过滚轮与内门架的第二滚道可上下滚动;所述电力驱动单元连接起升单元。本发明内部设置了活动配重,在内门架、叉头上升时,活动配重下降,其高位的势能转化为叉头起升的动能并最终转化为叉头处于高位的势能,减少了电机的电能输出,节约能量,而活动配重上升所需的能量来自于叉头下降,没有额外的能量输入,降低能量投入,同时活动配重的设置,电机带动叉头上移过程中所需要的输出功率也相应降低。
