In the construction of roads, especially high-grade roads, loaders are used for the filling and excavation of roadbed works, asphalt mixing, and aggregate and loading of cement concrete stockyards.
Walking structure:
1. Wheel Loader:Light weight, fast speed, flexible, high efficiency, difficult to damage the road surface, large ground pressure, poor passability, but widely used;
2. crawler loader:Ground pressure is small, good passability, low center of gravity, good stability, strong adhesion, large traction, greater than the cutting force, low speed, relatively poor flexibility, high cost, easy to damage the road when walking
