Differences among Scrapers, Loaders, Bulldozers and Excavators

Loaders are generally seen in seaports and logistics centers, mainly handling containers. The grader is a kind of common engineering machinery, mainly used for excavating soil, loading, demolition, digging, gravel and so on. The shoveler mainly shovels soil, snow and loads the truck in the same scope as the excavator, but the working conditions are limited and the efficiency is higher than that of the excavator. The shoveler can not work in soft soil and steep ditches. Generally, the shoveler is wheeled. Bulldozers are mainly bulldozers, bulldozers, loosening, and other functions, so in many areas of development can be seen excavators and bulldozers work together, the efficiency is very high. As the name implies, a scraper is to shovel and transport soil. It usually shovels soil away in its "belly" where there is too much soil. It can walk up to 500 meters to 2000 meters to unload the soil and put it where it needs soil!! A loader loads bulk materials into vehicles or other equipment on a self-propelled loading and unloading machine. Loaders can also carry out mild excavation work, through the replacement of the corresponding working devices, but also for bulldozing, lifting, loading and unloading wood and steel pipes and other operations. The scraper can be used as a loader, but the loader can not be used as a scraper. A tractor-driven machine with a wide blunt horizontal shovel for clearing land, road structures, or similar work.
