The invention provides a method for improving the bearing capacity of a forklift. The method comprises the following steps that S100, the forklift lifting weight increment delta G is preset; s200, according to a moment balance formula in the forklift lifting process, delta L = (delta G.L3)/G2 is calculated, delta L is the axle distance of a forklift body needing to be increased, L3 is the distance between the gravity center of goods and the center point of a front wheel, and G2 is the weight of a balancing weight; and S300, determining the increased wheelbase of the forklift body based on the delta L. According to the lifting capacity actually needed to be increased by the forklift, according to the moment balance principle, moment balance generated by a forklift body system, the balancing weight and carried goods relative to the center O of the front axle is achieved, under the condition that the weight of the balancing weight is not changed, the length of the gravity center of the balancing weight needing to move backwards is calculated, and the length of the forklift body and the distance between the front axle and the rear axle are increased by corresponding lengths; and the effects of increasing the lifting capacity and improving the bearing capacity of the forklift can be achieved by lengthening the axle distance.

    本发明提供一种提高叉车承载能力的方法,包括以下步骤:S100:预设一叉车起重重量增加量ΔG;S200:根据叉车起重过程中的力矩平衡公式,计算ΔL=(ΔG·L3)/G2,其中,ΔL为需增加车身轴距,L3为货物重心距离前轮中心点的距离,G2为平衡重重量;S300:基于前述ΔL确定叉车车身增加的轴距。本发明中,根据叉车实际需要增加的起重量,按照力矩平衡原理,车身系统、平衡重和承载货物相对前桥中心O处产生的力矩平衡,保证平衡重重量不变的情况下,计算出平衡重重心需要后移的长度,将车身长度和前后桥的距离增加相应的长度,即轴距加长,即可达到增加起重量,提高叉车承载能力的效果。
