一般装载机在动臂举升时,铲斗重心运动的轨迹是一条曲线,当铲斗从地面举起过程中,其铲斗和载荷重心与装载机前轮的距离逐渐增大,因而,它对装载机产生的翻倒力矩也随之增大。铲斗产生最大翻倒力矩时的离地高度,一般与装载机运输时铲斗的高度一致,这是一个决定铲斗斗容量的重要参数,当加大装载机斗容,为保持装载机运输时的稳定性则必须在装载机后部增加平衡重,同样,如用增大动臂长

When the general loader lifts the boom, the trajectory of the center of gravity of the bucket is a curve. When the bucket is lifted from the ground, the distance between the bucket and the center of gravity of the bucket and the front wheel of the loader gradually increases. Therefore, The overturning moment to the loader also increases. The bucket height when the bucket overturns moment is the same as the bucket height when the loader is transported. This is an important parameter that determines the bucket bucket capacity. When the loader bucket capacity is increased, in order to keep the loader transported When the stability of the loader must be added in the balance weight, the same, as with the increase boom length
