采取措施防止车辆倾覆。如果站立转矩之和大于倾覆转矩之和，则表明存在稳定性。确定扭矩的参考值是小费线。例如，对于三轮叉车，倾斜线由三个胎面区域的连接确定。静扭矩是位于地基内的所有力及其作用点相对于所考虑的倾角线的距离的乘积。倾覆扭矩是位于地面外部的所有力及其作用点相对于所考虑的倾卸线的距离的乘积。

        Measure against overturning of trucks. Stability is present if the sum of the standing torques is higher than the sum of the overturning torques. Reference value for the determination of torques is the tipping line. For three-wheel lift trucks, for example, the tipping line is determined by the connection of the three tread areas. Standing torques are the products of all forces that are located within the ground base and the distance of their point of application with respect to the considered tipping line. Overturning torques are the products of all forces that are located outside the ground base and the distance of their point of application with respect to the considered tipping line.
