Engine power: Power is greater than 515kw for extra-large loaders, power is 74 ~ 147Kw for medium-sized loaders. If the power is less than 74w, it is a small-sized machine, and if it is 147-515w, it is a large loader.
Transmission form: hydraulic transmission: stepless speed regulation, easy operation, but poor startability, generally only used on small loaders; hydraulic-mechanical transmission, small impact vibration, long service life of transmission parts, and convenient longitudinal damage , The speed between the vehicle and the external load can be automatically adjusted, generally used in large and medium loader; electric drive: stepless speed regulation, reliable work, simple maintenance, high cost, generally used on large loader.
Walking structure: crawler type: low ground pressure, good passability, low center of gravity, good stability, strong attachment, high traction, large specific cutting force, low speed, relatively poor flexibility, high cost, and walking Easy to damage the road. Tire type; light weight, fast speed, flexible maneuverability, high efficiency, not easy to damage the road surface, large ground pressure, poor passability, but widely used.
Loading and unloading method: Rotary type: The working device is installed on a turntable that can rotate 360 °. The side unloading does not need to turn around, and the work efficiency is high, but the structure is complex, the quality is high, the cost is high, and the side stability is poor. It is suitable for small and small Site; front unloading type: simple structure, reliable work, good vision, suitable for various operating sites, wide application; rear unloading type: front loading, back end unloading, high efficiency and poor safety of operation.
