Selection Principles Of Loaders

1. Model selection: mainly based on the working occasion and purpose. Generally, tire loaders with anti-skid chains are used for operations in quarries and soft bases;
2. Power selection: generally, diesel engines for construction machinery are used. When working in special areas, such as places with an altitude of more than 3000m, special plateau diesel engines should be used;
3. Transmission type selection: generally, hydraulic-mechanical transmission is used. The key component is the choice of torque converter. Loaders produced in China mostly use twin turbines and 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-plate type. The driving mechanism of the brake generally uses a force-adding device, and its power source is compressed air, gas-top oil and hydraulic type. The commonly used is the gas-top oil brake system, and a dual-circuit brake system is generally used to improve driving safety.
