摘　　要：反映装载机性能的主要力学指标——最大牵引力、掘起力和最大提升力,常常作为用户选型时重要的对比参数,在一些招投标文件中这些力学指标也较多作为招标条件。通常认为,这几个数值越大,代表装载机作业时铲装能力、工作效率越好。但实际情况并非简单如此,整机铲装能力的发挥,除了受到整机质量和桥荷分配、场地条件等影响,这三大力学指标之间也在一定条件下相互影响。It is to see to it that what to present a loader's performance is its mechanical indicators,i.e.max drawbar pull,digging force,and max lift,which are often used as comparison data for users to choose their subject types,same is true for these indicators as bidding conditions in the invitation documents.It is a common recognition that for these data of a loader the higher the data the better the capability and the efficiency in operation.However,to put it simply all of them are not true.These 3 indicators would interact under certain conditions,besides to exert a loader's operational capability to the full will be affected by the mass and axleload distribution of the whole machine,not to say by the job-site conditions.
