The forklift safety speed limiting system comprises a safety speed limiting switch, a gearbox control panel and a gear handle, the gear handle is provided with a first output port and a second output port, the gearbox control panel is provided with a first input port and a second input port, and the second output port is electrically connected with the second input port through a first execution part. The first output port is electrically connected with the first input port through the second execution part, the second output port is electrically connected with the first input port through the third execution part, on-off of the safety speed limiting switch is used for changing on-off of the first execution part, the second execution part and the third execution part, the first execution part and the second execution part are of a normally-closed structure, and the third execution part is of a normally-open structure; when the second input port inputs a low level, the gearbox executes a low-speed gear, and when the second input port inputs a high level, the gearbox executes a high-speed gear. The invention further discloses the forklift with the forklift safety speed limiting system. According to the invention, speed limiting can be carried out without modifying a whole vehicle control program or a gearbox control program, so that the safety of the forklift is improved.

    本发明公开了一种叉车安全限速系统,包括安全限速开关、变速箱控制板和档位手柄,档位手柄设有第一、第二输出端口,变速箱控制板设有第一、第二输入端口,第二输出端口通过第一执行部与第二输入端口电连接,第一输出端口通过第二执行部与第一输入端口电连接,第二输出端口通过第三执行部与第一输入端口电连接,安全限速开关的开闭用于改变第一、第二和第三执行部的通断,第一和第二执行部为常闭结构,第三执行部为常开结构;第二输入端口输入低电平时变速箱执行低速档位,第二输入端口输入高电平时变速箱执行高速档位。本发明还公开了具有叉车安全限速系统的叉车。本发明不需要修改整车控制程序或变速箱控制程序进行限速,提高叉车的安全性。
