Earth-moving machinery. Determination of average ground contact pressure for crawler machines Ingestion-build-68772 and" component and system failure1 Scope This International Standard specifies a uniform method for calculating the average ground contact pressure of self propelled and towed crawler (track laying) earth moving machines, as defined in ISO 6165, on soft surfaces with empty equipment or attachment. The average ground contact pressure value is used only for comparing different machine models. Actual ground contact pressure values under operating conditions will vary depending on load,
