Bulldozer is a self-propelled construction machine with bulldozing device and control mechanism installed in front of crawler tractor or tire tractor. Because it can achieve a variety of construction effects, it can be applied to a variety of construction projects. So how are bulldozers classified?

According to the walking mode, the bulldozer can be divided into crawler bulldozer: it is a multi-purpose model with large traction force, small grounding specific pressure, strong climbing ability and superior operation performance. Tire bulldozer: it has the advantages of fast driving speed, good mobility, short operation cycle time, convenient and rapid transfer, and does not damage the ground. It is especially suitable for urban construction and road maintenance projects.

According to the installation of the bulldozer plate, it can be divided into fixed blade bulldozers: the bulldozer blade is fixed at right angles to the longitudinal axis of the main engine, also known as shovel bulldozers. Its mechanism is simple, but it can only push the soil in the forward direction, and its operation flexibility is poor. It is only used for small and medium-sized bulldozers. Rotary blade bulldozer: the bulldozing blade of the bulldozer can rotate a certain angle in the horizontal plane, and can be installed at a fixed right angle or non right angle with the longitudinal axis of the main engine.

In addition to ordinary bulldozers, there is also a special bulldozer. It has strong specificity and is only suitable for construction in special environment. For example, wetland bulldozers and amphibious bulldozers.
