The Komatsu 21T-32-31111 Track Shoe is a genuine OEM-specification undercarriage component designed for the Komatsu PC2000 series mining excavators (PC2000, PC2000-8, PC2000-11). This track shoe attaches to the track link assembly to provide traction and flotation for the machine.
The PC2000 series are ultra-class mining excavators used in large-scale surface mining, heavy excavation, and overburden removal. The 810mm width provides excellent stability and flotation in mining conditions, distributing the machine's extreme weight over a larger surface area to reduce ground pressure.
