1. Engine power:


① Power is less than 74kw for small loaders.

②Power is 74 ~ 147kw for medium loader

③ Power is 147 ~ 515kw for large loaders

④ Power is greater than 515kw for extra large loaders


2. Transmission form:


①Hydraulic-mechanical transmission, small impact vibration, long life of transmission parts, convenient operation, automatic adjustment between vehicle speed and external load, generally used in medium and large loaders;

②Hydraulic transmission: stepless speed regulation, easy operation, but poor startability, generally only used on small loaders;

③ Electric drive: stepless speed regulation, reliable operation, simple maintenance, high cost, generally used in large loader.


3. Walking structure:


①Tire type: light weight, fast speed, flexible maneuverability, high efficiency, not easy to damage the road surface, large ground pressure, poor passability, but widely used;

②Crawler type: grounding pressure is small, good passability, low center of gravity, good stability, strong adhesion, high traction, large specific cutting force, low speed, relatively poor flexibility, high cost, easy to damage the road when walking.


4. Loading and unloading methods:


①Front unloading type: simple structure, reliable work, good vision, suitable for various operating sites, and widely used;

②Rotary type: The working device is installed on a turntable that can be rotated 360 °. The side unloading does not need to turn around, high efficiency, but complex structure, large quality, high cost, poor side stability, suitable for smaller venues.

③ Rear unloading type: front-end loading, rear-end unloading, high operation efficiency, and poor operation safety.
