The invention discloses an anti-rollover method and system for a telescopic arm forklift. The method comprises the steps that whole vehicle structure data and oil cylinder structure parameters of the forklift, pressure data of an oil cylinder under the current operation posture and working state data of a suspension arm are received; on the basis of the whole vehicle structure data and the working state data of the suspension arm, the amplitude and the height of the suspension arm under the current operation posture are calculated, and the maximum load capacity under the current operation posture is determined by combining the amplitude and the height of the suspension arm and the forklift load curve graph; based on the whole vehicle structure data, the oil cylinder structure parameters, the pressure data of the oil cylinder under the current operation posture and the working state data of the suspension arm, the current load capacity is calculated, and the load percentage is obtained according to the maximum load capacity and the current load capacity; when the load percentage exceeds a preset alarm value, an alarm signal is sent out, a control signal for increasing the angle of the suspension arm or reducing the length of the suspension arm is generated, and the suspension arm of the forklift is limited to move towards the dangerous direction; the anti-tipping device can effectively prevent the telescopic boom forklift from tipping over.

    本发明公开了一种伸缩臂叉车防倾翻方法及系统,所述方法包括:接收叉车的整车结构数据、油缸结构参数,以及当前作业姿态下油缸的压力数据和吊臂的工作状态数据;基于整车结构数据及吊臂的工作状态数据,计算当前作业姿态下吊臂的幅度和高度,并结合吊臂的幅度和高度以及叉车载荷曲线图,确定当前作业姿态下的最大载荷量;基于整车结构数据、油缸结构参数以及当前作业姿态下油缸的压力数据和吊臂的工作状态数据,计算当前载荷量,并根据最大载荷量和当前载荷量,得到载荷百分比;当载荷百分比超过预设报警值时,发出报警信号,生成使吊臂角度增大或吊臂长度减小的控制信号,限制叉车吊臂朝危险方向运动;本发明能够有效防止伸缩臂叉车倾翻。
