1 Scope

The ISO 6165 standard specifies the definition of self-propelled and towed earthmoving machinery crawler (caterpillar type) on loose surfaces, and work clothes When set to no-load or attachment, calculate the average ground pressure of a unified approach. Comparing the average ground pressure than the value only for different types of machines, the actual ground pressure values \u200b\u200bdue to the load center of gravity location, terrain, shoe Zone plate type and size, ground conditions change. Note 1. The grounding some special family of machines than other methods can be used to determine the pressure. Note 2. This calculation allowed to penetrate the soil surface and the support it support area is increased.
