On the other hand, grade ability of wheel loader is 25 degrees. Since this slope is 30 degrees, it will not make it. Construction equipment with a crawler such as bulldozers and a hydraulic excavators have higher grade ability performance than those with wheels such as a wheel loader or a dump truck.

The secret is how firmly a crawler can keep it on the ground. A crawler grabs the ground more firmly than wheels, which makes it easier to climb up steeper slopes.
