Selection principle of loader model

The loader is a kind of taxi stonework construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used to shovel and load bulk materials such as soil, sand, lime, coal, etc., and also can perform light shoveling operations for ores, hard rocks, etc. Commonly used single-bucket loaders are classified according to engine power, transmission type, walking system structure and loading mode. Then let’s introduce the classification and use of loader.

Model selection

It is mainly selected and determined according to the operation site and purpose. Generally, operations are carried out in quarries and soft bases, and tire loaders with anti-skid are mostly used Chain;

Power selection

Generally, diesel engines for construction machinery are mostly used, and special plateau diesel engines shall be used for operation in special areas, such as places with altitude higher than 3000m;

Selection of transmission type

Generally, hydraulic-mechanical transmission is selected. The key component is the choice of torque converter form. Most loaders produced in China use dual-turbine and single-stage two-phase hydraulic torque converter.

Selection of braking performance

When selecting a loader, the braking performance of the loader should also be fully considered, including multiple in-service 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 adopts an afterburner, and its power source includes compressed air, air top oil and hydraulic type. Gas cap oil is commonly used
The braking system generally adopts a dual-circuit braking system to improve driving safety.
