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。
The main mechanical indexes that reflect the performance of the loader - the maximum traction, the lifting force and the maximum lifting force, are often used as the important comparison parameters for the user selection. In some bidding documents, these mechanical indexes are also used as the bidding conditions. It is generally believed that the larger the values are, the better the work efficiency is. However, the actual situation is not so simple. In addition to being affected by the quality of the entire machine and the distribution of bridge load and site conditions, the three mechanical indicators also exert their influence under certain conditions.
