The loader is a kind of earthwork construction machinery which is widely used in highway, railway, construction, hydropower, port, mine and other construction projects. Wheel Loader It is mainly used for shoveling soil, Wheel Loader sand, lime, coal and other bulk materials. , Hard soil and other minor shoveling operations. Dress up different auxiliary work equipment can also be carried out, lifting and other materials such as timber loading and unloading operations. Wheel Loader In the construction of roads, especially in high-grade highways, the loaders are used for filling and filling of roadbed works such as filling and digging, asphalt mix and cement concrete field. Wheel Loader In addition can also push the soil, scraping the ground and traction other machinery and other operations. As the loader has the advantages of fast operation, high efficiency, good mobility and light operation, Wheel Loader it is one of the main models of earthwork construction and mining in engineering construction.
In the 1920s, the world's first loaders were based on agricultural tractors,Wheel Loader which were mainly used for construction sites or to store and process materials. Wheel Loader Most of the loading accessories are installed in the solid tire tractor operation, the process is relatively rough, Wheel Loader coupled with the use of bulky rope driven robot arm, with complex operation, the performance of the shortcomings of instability, and the operation process prone to danger.
This is a 20 early loader, bucket capacity of 0.753 cubic meters, Wheel Loader load 680 kg. The use of gantry structure, the use of rope to fight the way to work. The structure of the loader during this period is characterized by the front of the engine, the front wheels are small, Wheel Loader the rear wheels are large, the single-bridge drive, the front wheel steering, the gantry-type working device, the steel rope lifting the bucket, Wheel Loader the tractor site, Bucket cut into the small, low operating speed.
The early wheel loader had no small safety problems, Wheel Loader and one of the main problems was the pivot arm position behind the operator, which was likely to be caught between the loader arm and the hydraulic cylinder. With the US National Security Council and the manufacturer to carry out the reconstruction design of the 20th century, 60 years, is the wheel loader capacity by leaps and bounds ten years. Manufacturers are in the development of large loaders and applications with mines, articulated loaders are widely used, Wheel Loader the advantages of articulated steering is: the bucket with the front frame steering, to meet the in situ steering; with a rigid frame, Wheel Loader a job cycle The average travel distance of 51%, 50% increase in production efficiency; turning radius is small, flexible, suitable for narrow site operations.
