Differences between scrapers, loaders, bulldozers, and excavators:
Loaders are commonly seen in seaports and logistics centers, primarily used for loading and unloading containers. Graders are used for leveling roads, snow removal, bulldozing, and loosening soil. Excavators are common construction machinery, mainly used for digging soil, loading trucks, demolition, excavation, and crushing rocks.
Scrapers are mainly used for shoveling soil and snow, and loading trucks. Their application range is similar to excavators, but their operating conditions are limited. They are more efficient than excavators. Scrapers cannot operate in soft soil or in steep ditches. Generally, scrapers are wheeled. Bulldozers are mainly used for bulldozing, leveling, and loosening soil. Therefore, in many development areas, excavators and bulldozers can be seen working together, achieving very high efficiency. Scrapers, as the name suggests, are used for shoveling and transporting soil. They typically scoop up soil from areas with abundant soil, store it in their cargo compartment, and then travel 500 to 2000 meters to unload the soil and place it where it is needed. A loader is a self-propelled loading and unloading machine that loads bulk materials onto vehicles or other equipment. Loaders can also perform light digging work, and by changing the working devices, they can also perform bulldozing, lifting, loading and unloading of timber and steel pipes, etc. A scraper can be used as a loader, but a loader cannot be used as a scraper. A bulldozer is a tractor-driven machine with a wide, blunt horizontal blade used to clear land, road structures, or similar work.
