Difference Between Loader and Bulldozer Difference Between Loader and Scraper Apr 18 , 2022
What is the difference between bulldozers, scrapers and loaders?
1. Bulldozer
Bulldozers are a main type of earthmoving machinery. They are divided into two types: crawler type and tire type. Because there are fewer tire type bulldozers. This article mainly describes the structure and working principle of the crawler bulldozer.
The basic operations of bulldozer excavation are: A. Shoveling B. Earthmoving C. Unloading.
2. Scraper

A scraper is a machine that can comprehensively complete excavation, earthmoving, unloading, filling and leveling. According to the different traveling mechanisms, it can be divided into towed scrapers and self-propelled scrapers. According to the different operating systems of the scraper, it can be divided into hydraulic and cable scrapers. The scraper has flexible operation, is not restricted by terrain, does not need special roads, and has high production efficiency.

3. Loader
Loader is a kind of earth and stone construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shovel loading of soil, sand, lime, coal and other bulk materials. Minor shovel excavation for ore, hard soil, etc. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. In roads, especially in the construction of high-grade highways, loaders are used for filling and excavating roadbed engineering, aggregate and loading of asphalt mixture and cement concrete yard. In addition, it can also carry out operations such as pushing soil, leveling the ground and pulling other machinery. Because the loader has the advantages of fast operation speed, high efficiency, good maneuverability, and easy operation, it has become one of the main types of earthwork construction in engineering construction.
Scrapers, as the name implies, are shoveling and transporting!! Scrapers generally shovel the soil in the place where there is a lot of soil and put it in its "belly", and then go up to 500 meters to 2000 meters to unload the soil and put it on the need. Dirt place!!
Loader is a self-propelled loading and unloading machine that loads bulk materials into vehicles or other equipment. The loader can also perform light excavation work, and can also perform operations such as bulldozing, lifting, loading and unloading wood and steel pipes by changing the corresponding working devices.
A scraper can be used as a loader, but a loader cannot be used as a scraper.
Bulldozer A tractor-driven machine with a wide, blunt horizontal blade for clearing land, road structures or similar work.
