Loader selection principle

1. Selection of the model: It is mainly selected and determined according to the operation and use. Generally, operations are carried out in quarries and soft bases, and crawler loaders are often used;

2, the choice of power: generally use engineering machinery with diesel engines, operating in special areas, such as altitudes above 3000m, special high-profile diesel engines should be used;

3, the choice of transmission type: generally use hydraulic-mechanical transmission. The key component is the choice of the torque converter form. At present, the loaders produced in China mostly use twin-turbo, single-stage two-phase liquid torque devices.

4. When selecting the loader, fully consider the braking performance of the loader, including multiple brakes, parking brakes and emergency brakes. The brakes are hoofed, caliper and wet multi-piece. The driving mechanism of the brake generally adopts a force device, and the power source thereof is compressed air, gas top oil and hydraulic type. At present, the gas top oil brake system is commonly used, and a double circuit brake system is generally used to improve the safety of driving.
