ABSTRACT:
Vibration or the like is prevented for long-term use by normalizing, with operation continuing, a tread of a crawler belt link through grinding in an early stage where uneven wear such as corrugated wear occurs. With a crawler belt of a crawler vehicle wound, an abrasive plate for grinding the tread of the crawler belt link is disposed to contact the tread. While the crawler vehicle does normal traveling work, the abrasive plate corrects the tread of the crawler belt link for the uneven wear. The vibration of a vehicle body can thus be prevented during travel with no uneven wear produced.
