# How to Correctly Choose a Wheel Loader

1. Selection of machine model: The selection and determination are mainly based on the working site and purpose. Generally, when working in quarries and soft ground, crawler loaders are mostly selected. 2. Selection of power: Generally, diesel engines for construction machinery are mostly used. When working in special regions, such as places with an altitude above 3000 m, special plateau diesel engines should be used. 3. Selection of transmission type: Generally, hydro-mechanical transmission is 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. There are three types of brakes: shoe brakes, caliper disc brakes, and wet multi-disc brakes. The driving mechanism of the brake generally adopts a booster device, and its power source includes compressed air, air-over-oil, and hydraulic types. At present, the commonly used one is the air-over-oil braking system, and a dual-circuit braking system is generally adopted to improve driving safety. 5. Working conditions, workload, and operator working intensity: The selection of the loader is mainly considered according to working conditions, workload, operator working intensity, and other factors.
