The wheels and brakes used on wheeled excavators last longer, cost less and are fairly easy to replace, giving these machines a low operating cost.
Do excavators have wheels or tracks?

What is an excavator on wheels called?
The crawler excavator (also referred to as the standard excavator) is called a crawler because it runs on two rotating tracks instead of wheels—in much the same way a tank does. The crawler uses hydraulic power and although it’s slower than a wheeled excavator, its tracked chassis makes it more stable.
Why do excavators have tracks instead of wheels?
Tracked machines have a much greater ground contact area than wheeled equipment. The length and width of tracks cover a larger area than wheels do. … Tracks actually work to float the machine over the ground rather than cut into it. On ground conditions that are hard and flat, weight distribution is not a large concern.
Are wheeled excavators road legal?
Wheeled excavators offer much faster travel times around site and can be driven legally on public roads in many European countries, which can save on transportation costs. … They are arguably more versatile machines, but are expensive to transport from site to site.
