Wheel loaders are a type of construction machinery widely used in the engineering and construction field. They are primarily used for scooping, loading, and short-distance transportation of bulk materials such as soil, sand, gravel, lime, coal, and for light excavation of ore and hard soil. They have important applications in various fields, including roads, railways, construction, water conservancy, ports, mining, and agriculture. 

Wheel loaders are characterized by their fast working speed, high efficiency, strong maneuverability, and simple operation, making them an indispensable machine in earthmoving and construction projects. Wheel loaders are typically equipped with powerful diesel engines and utilize hydraulic-mechanical transmission. They feature multiple braking systems to ensure safe operation, including service brakes, parking brakes, and emergency brakes. Different models, power types, and transmission types can be selected according to the working environment and requirements.
