Bulldozer by way of walking

Bulldozers can be divided into two types of crawler type and tire type. The crawler bulldozer has the advantages of large traction force, small ground pressure ratio (0.04 0.13MPa), strong climbing ability, but low driving speed. The tyre type bulldozer has high driving speed, flexible maneuver, short operation cycle time, convenient transport transfer, but small traction power, which is suitable for frequent change of site and field work.
