Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a rotary loader. Background Art
[0002] A loader is a kind of earthwork construction machinery widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. It is mainly used to shovel and load bulk materials such as soil, sand, lime, coal, etc. It 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. 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. However, the bucket of the current loader is at the front end of the wheel and can only work in front of the wheel. If it wants to work on the side or rear of the wheel, it needs to drive the wheel and turn the direction to work, which will limit the operation in narrow places such as tunnels and one-way streets where it is not easy to turn or turn around.
