The invention provides a forklift rollover prediction method and system and a forklift, and the method comprises the following steps: detecting the posture state of a forklift portal in real time, and obtaining the inclination angle of the portal when the portal inclines; the acting force of an inclined oil cylinder connected between the portal and the forklift body is obtained; actual tipping moment is obtained according to the acting force of the inclined oil cylinder and the inclination angle of the portal frame; obtaining the self-weight moment of the portal according to the inclination angle of the portal; a longitudinal stability coefficient is obtained according to the actual tipping moment, the self-weight moment of the portal and the built-in longitudinal stabilizing moment, and when the longitudinal stability coefficient exceeds a set threshold value, an early warning is given out.
本申请提供了一种叉车倾翻预测方法、系统及叉车,包括以下步骤:实时检测叉车门架的姿势状态,当门架发生倾斜时获取门架的倾斜角度;获取连接在门架与叉车本体之间的倾斜油缸的作用力;根据倾斜油缸的作用力和门架的倾斜角度获得实际倾翻力矩;根据门架的倾斜角度获得门架自重力矩;根据实际倾翻力矩、门架自重力矩和内置的纵向稳定力矩获得纵向稳定性系数,当纵向稳定性系数超过设定的阈值时发出预警。
