INTRODUCTION:

System Life and Components Wear
Life and wear are generally related to ground characteristics and the environment.
Ground Characterisitics
Abrasiveness Rating:
– High abrasiveness rated grounds include wet soils containing high amounts of hard and sharp sand particles.
– Moderate abrasiveness rated grounds include slightly damp soils that contain a low portion of rounded sand particles or rock fragments
– Low abrasiveness rated grounds include dry silt and clay soils without any content of rocks and sands
Impact:
– impact can be described as the amount of grouser penetration in the ground.
– The effect can be reduced by decreasing machine speed and by using the smallest track shoes possible.
– The weight of the machine is also a determining parameter, even if it can not be modified.
Packing
– Packing materials are any material that stick to or pack around moving components.
– Packing materials can be classified as extrudable and non-extrudable.
Major effects:
– Incorrect engagement between the components causing tightening of the track chain, high loads on the undercarriage components, interference and dramatically increases the wear rate.
– Abnormal increase of the wear effect due to abrasive particles incorporated in the packed material.
– Moderate amounts of moisture contribute to packing.
