Why do most megga diggers have catterpillar tracks instead of wheels?

Most mega diggers use caterpillar tracks instead of wheels because tracks distribute weight more evenly, providing better stability and traction on uneven or soft terrains. This design allows them to navigate challenging conditions, such as mud or gravel, without getting stuck. Additionally, tracks reduce ground pressure, minimizing soil disturbance and damage during operation. Overall, caterpillar tracks enhance the machine's performance and efficiency in heavy-duty excavation tasks.
