Machine Selection: The selection and determination are mainly based on the operating environment and purpose. For operations in quarries and soft soil areas, tire loaders equipped with anti-skid chains are commonly used.
Power Selection: Construction machinery diesel engines are generally used. For operations in special areas, such as altitudes above 3000m, special high-altitude diesel engines should be used.
Transmission Type Selection: Hydraulic-mechanical transmission is generally preferred. A key component is the torque converter type. Loaders manufactured in China often use dual-turbine, single-stage two-phase hydraulic torque converters.
When selecting a loader, braking performance must be fully considered, including multiple braking systems (parking brake, parking brake, and emergency brake). Brakes come in three types: shoe brake, caliper disc brake, and wet multi-disc brake. The brake drive mechanism generally uses a force-adjusting device, powered by compressed air, air-over-hydraulic, or hydraulic systems. Air-over-hydraulic braking systems are commonly used, and dual-circuit braking systems are generally employed to improve driving safety.
