Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects, it is mainly used for shoveling soil, sand, lime, coal and other loose materials, but also for ore, hard soil and other light shoveling and digging operations. The replacement of different auxiliary working devices can also be used to move earth, lift and load and unload other materials such as wood.
In the construction of roads, especially in the construction of high-grade highways, loaders are used for filling and digging of roadbed engineering, aggregate and loading of asphalt mixtures and cement concrete yards. In addition, it can also be used to push soil, scrape the ground and pull other machinery. Because the loader has the advantages of fast working speed, high efficiency, good mobility and light operation, it has become one of the main types of earthwork construction in engineering construction.
1.The diesel wheel loader uses the diesel engine as the power device, the hydraulic torque converter, the power shift transmission, the two-bridge drive and other components of the hydraulic mechanical transmission system (small tire loader some use hydraulic transmission or mechanical transmission), hydraulic control, articulated frame steering, the working device of the reverse rod mechanism.
2.Diesel wheel loader is a kind of earthwork application machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects, it is mainly used for shoveling soil, sand, lime, coal and other loose materials, but also for ore, hard soil and other light shoveling and digging operations. It plays an important role in reducing labor intensity, speeding up construction speed and improving project quality.
3.The main function of diesel wheel loader is to shovel loose materials and transport short distances. It is one of the fastest growing, production and sales and market demand of construction machinery. We usually see the most is the wheel loader, and it is the opposite of the crawler loader.
