Difference between scraper, loader, bulldozer and excavator
Loaders usually appear in seaports and logistics centers and are mainly used for loading and unloading containers. The grader is used to shovel the road surface, remove snow, bulldoze, loosen soil and other functions. Excavator is a common construction machinery, mainly used for digging soil, loading, demolition, excavation, gravel, etc. Forklifts are mainly used to shovel earth and snow. The applicable scope of loading is similar to that of excavator, but the operating conditions are limited and the efficiency is higher than that of excavator. Forklifts cannot be operated in soft soil and steep ditches. Generally speaking, forklifts are wheeled. Bulldozers are mainly used for bulldozing, leveling and scarifying. Therefore, excavators and bulldozers can be seen to work together in many developed places with high efficiency. As the name implies, scrapers are used to shovel and transport soil. Generally, the scraper shovel the soil in the place with more soil and put it into its "stomach". It can walk from 500 meters to 2000 meters, unload the soil and put it where it is needed. Loader A self-propelled loader that loads bulk materials onto vehicles or other equipment. The loader can also perform light shovel operation. It can also bulldoze, lift, load and unload wood and steel pipes by changing the corresponding working device. Scrapers can be used as loaders, but loaders cannot be used as scrapers. A tractor driven machine equipped with a wide, blunt horizontal bulldozer for clearing land, road structures, or similar work.
