The invention discloses a forklift lifting height and running speed correction system which is composed of a forklift control system, a forklift speed detection device, a wheel steering angle detection device, a pallet fork lifting height detection device and a sound-light alarm device. The correction method comprises the steps that whether the forklift decelerates or cannot continue to be lifted or not is judged according to the running speed and the steering angle of the forklift and the lifting height of the pallet fork, and the control system can conduct early warning in advance through the sound-light alarm device before the critical value is reached. According to the method, information of the driving speed, the steering angle and the lifting height of the pallet fork of the forklift is collected and analyzed, judgment is carried out by combining preset values set in a control system by manufacturers, and when numerical values deviate from target values, the control system sends out an instruction of braking or action of a reversing valve; the situation that the driving speed, the steering angle and the lifting height of the forklift are not matched in the working process can be avoided, and the risk that the forklift overturns is effectively reduced.
本发明公开了一种叉车提升高度与行驶速度矫正系统,由叉车控制系统、叉车速度检测装置、车轮转向角度检测装置、货叉提升高度检测装置,声光报警装置组成。矫正方法包括:根据叉车的行驶速度、转向角度以及货叉的提升高度的来判断叉车是否采取减速或者不能继续提升,并且在到达临界值之前该控制系统能够通过声光报警装置提前预警。该方法中,对叉车行驶速度、转向角度、货叉提升高度三者的信息采集分析,结合各个厂家设置在控制系统里的预设值进行判断,当其有数值偏移目标值的时候,控制系统即发出制动或换向阀动作的指令,能够避免叉车在工作过程出现行驶速度、转向角度以及起升高度不匹配的情形,有效的降低叉车出现倾覆的危险。
