GB/T 30965-2014 in English

《GB/T 30965-2014土方机械 履带式机器平均接地比压的确定》由TC334（全国土方机械标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了ISO6165中定义的自行式和拖式履带式(链轨式)土方机械在松软路面上,且工作装置或附属装置无载时,计算平均接地比压的统一方法。
该平均接地比压的值仅用于不同型号机器的比较,实际接地比压值将由于负载、重心位置、地形、履带板类型和规格、地面条件等而改变。
注1:某些特殊机器族的接地比压可选用其他方法确定。
注2:该计算允许穿透支撑土壤面而使其支撑区域增大。

Scope

This standard specifies the unified method for calculating the average ground specific pressure for self-propelled and towed crawler-type (chain-rail) earth-moving machines defined in ISO 6165 when the working device or attachment is unloaded on a soft road surface. The average ground specific pressure value is only used for comparison of different models of machines, and the actual ground specific pressure value will change due to load, center of gravity position, terrain, track shoe type and specification, ground conditions, etc.
