How to Choose a Wheel Loader?

Loaders are common earthmoving machinery. By installing different auxiliary working devices, they can perform bulldozing, lifting, and other operations, such as loading and unloading timber. In highway construction, especially in high-grade highway construction, loaders can be used for filling and excavating subgrade engineering, as well as stockpiling and loading aggregates at asphalt mixture and cement concrete material sites. In addition, loaders can also carry out operations such as pushing and transporting soil, leveling the ground, and towing other machinery. Because loaders have advantages such as fast operation speed, high efficiency, good mobility, and easy operation, they have become one of the main types of machinery in earthwork and stonework construction in engineering construction. When purchasing a loader, how should one choose correctly? Generally speaking, the following four principles should be followed: 1. Selection of model: Selection and determination are mainly based on the working site and purpose. Generally, when working in quarries and on soft ground, crawler loaders are mostly selected. 2. Selection of power: Diesel engines for engineering machinery are generally mostly used. When working in special regions, such as places with an altitude higher than 3000 m, special high-altitude diesel engines should be used. 3. Selection of transmission type: Hydraulic mechanical transmission is generally selected. The key component is the selection of the torque converter type. At present, loaders produced in China mostly use dual-turbine, single-stage two-phase hydraulic torque converters. 4. Consideration of the braking system: When selecting a loader, the braking performance of the loader must also be fully considered, including service braking, parking braking, and emergency braking. Brakes include shoe type, caliper disc type, and wet multi-plate type. The driving mechanism of the brake generally adopts a booster device, and its power source includes compressed air, air-over-oil, and hydraulic type. At present, the commonly used one is the air-over-oil braking system, which generally adopts a dual-circuit braking system to improve driving safety.
