Crawler Excavator vs. Wheeled Excavator
Crawler excavator: Lower ground pressure (often 35–55 kPa with wide track shoe width) suits soft subgrade, deep digging depth, and high breakout force work. Most quarry and highway cut sites specify crawlers when operating weight stays on one pad for weeks.
Wheeled excavator: Road travel without a lowboy cuts mobilization cost on urban paving and multi-site utility shifts. Trade-off: higher ground pressure on soft fill and less stability when digging depth and stick force rise near slope edges.
Link-Belt field packs list both options with operating weight, bucket capacity (m³), and gradeability so the geotech report—not habit—decides the undercarriage.
