Technical Features

What Is a Track Dozer?

Also known as a crawler, a track dozer moves on tracks similar to what you might think of on a tank. These tracks are often steel but can also be rubber. The tracks disperse the machine’s weight more widely than tires do, helping keep the heavy equipment above ground and preventing sinking in challenging environments such as mud, clay, rocks and sand. The tracks also won’t puncture when moving over pieces of rubble, which can happen when wheeled dozers encounter rough terrain.

Tracks help the machine operate up and across different grades or uneven surfaces, too. You could be working on a steep incline or an area that gradually declines, and the tracks will hold the bulldozer in place to prevent tipping. Because a dozer’s tracks evenly distribute its weight to form a lower center of gravity, it’s ideal for off-road landscapes, rough terrain, slippery areas and field work.
