1. Bulldozer
Bulldozers are a major type of earth-moving machinery, which are divided into crawler and tire types according to the walking mode. Because tire bulldozers are relatively rare. This article mainly describes the structure and working principle of crawler bulldozers.
The basic operations of bulldozer excavation are: A. Shoveling B. Transporting C. Unloading.
2. Scraper
A scraper is a machine that can comprehensively complete excavation, transportation, unloading, filling and leveling. According to the different walking 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 rope scrapers. The scraper is flexible to operate, not restricted by terrain, does not require special roads, and has high production efficiency.
3. Loader
A loader is a type of earthwork machinery widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used to shovel soil, sand, lime, coal and other bulk materials, and can also do light shoveling operations on ore, hard soil, etc. By replacing different auxiliary working devices, it can also perform bulldozing, lifting and loading and unloading operations of other materials such as wood. In road construction, especially in high-grade highway construction, loaders are used for filling and excavation of roadbed projects, asphalt mixture and cement concrete material fields, etc. In addition, it can also carry out operations such as pushing soil, leveling the ground, and towing other machinery. Because loaders have the advantages of fast operation speed, high efficiency, good maneuverability, and easy operation, they have become one of the main types of earthwork construction in engineering construction.
As the name implies, a scraper is used to shovel and transport soil!! Scrapers usually shovel soil away from places with a lot of soil and put it in their “belly”, then walk 500 to 2,000 meters at most to unload the soil and put it where the soil is needed!!
A self-propelled loading and unloading machine that loads bulk materials onto vehicles or other equipment. Loaders can also perform light shoveling work, and by replacing the corresponding working devices, they can also perform operations such as bulldozing, lifting, loading and unloading wood and steel pipes.
A scraper can be used as a loader, but a loader cannot be used as a scraper.
A bulldozer is a machine driven by a tractor, with a wide and blunt horizontal blade for clearing land, road structures or similar work.
