1. Selection of models: The selection and determination are mainly based on the operation occasion and use. Generally, the operation is carried out in quarries and soft bases, and tire loaders are often used with snow chains;
2. Choice of power: Generally, diesel engines for construction machinery are used. In special areas, such as places with an altitude higher than 3000m, special plateau diesel engines should be used;
3. Selection of transmission type: hydraulic-mechanical transmission is generally used. One of the key components is the choice of torque converter form. Loaders produced in China mostly use twin-turbo, single-stage two-phase hydraulic torque converters.
4. When selecting a loader, the braking performance of the loader should also be fully considered, including multiple braking, parking braking and emergency braking. There are three types of brakes: shoe type, caliper disc type and wet multi-disc type. The drive mechanism of the brake generally adopts the afterburner device, and its power source includes compressed air, air cap oil and hydraulic type. The most commonly used is the air-cap oil braking system, and the dual-circuit braking system is generally used to improve the safety of driving.
