The invention discloses a forklift gantry with a guide rail and a side roller structure, and a forklift. The forklift gantry comprises a plurality of gantry bodies, which are connected in a sleeved mode; each gantry body is provided with two sliding rail channel steels, which are parallel in the left-right direction, and at least one middle guide rail; the sliding rail channel steels and the middle guide rail are transversely connected with each other through at least two cross beams; at least one pair of side rollers is arranged on the two sides of the middle guide rail and located at the upper end and the lower end of each gantry body; and the side rollers make contact with the side surfaces of the middle guide rail on the adjacent gantry bodies. According to the invention, the guide rail and a side pulley structure are arranged between the mutually sleeved gantry bodies; when the gantry bodies ascend and descend, the distance between the side rollers changes along with the lifting height; when the gantry bodies are stacked laterally at a low position, the distance between the side rollers is large, the stress of the rollers is small, and the loading capacity is high; and a solid guide rail is arranged in the middle of each stage of gantry body, so that the strength of the gantry bodies during forward stacking is improved, and the strength of the gantry bodies during lateral stacking is also improved.
本发明公开了一种带导轨和侧滚轮结构的叉车门架及叉车,包括多个相互套接的门架,所述门架具有两个左右平行的滑轨槽钢和至少一个中间导轨,所述滑轨槽钢和中间导轨由至少两根横梁相互横向连接,所述中间导轨两侧、且位于每个门架上下两端至少布置一对侧滚轮,所述侧滚轮与相邻门架上的中间导轨侧面相接触。本发明通过在相互套接的门架之间设置导轨和侧滑轮结构,门架升降时,侧滚轮间距随起升高度而变化:低位侧向堆垛时,侧滚轮间距大,滚轮受力小,载荷能力高;各级门架中间布置实心导轨,既增加了门架正向堆垛时的强度,也增加了侧向堆垛时的强度。
