Commonly used single bucket loaders are classified according to engine power, transmission form, walking structure and loading mode.
1, engine power:
1 power less than 74kw for small loaders.
2 power 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:
1 hydraulic-mechanical transmission, small impact vibration, long life of transmission parts, easy to operate, automatic adjustment between speed and external load, generally used in medium and large loaders;
2 hydraulic transmission: stepless speed regulation, control room, but the startability is poor, generally only used on small loaders;
3 electric drive: stepless speed regulation, reliable work, simple maintenance, high cost, generally used on large loaders.
3. Walking structure:
1 Tire type: light weight, fast speed, flexible, high efficiency, not easy to damage the road surface, large ground pressure, poor passability, but widely used;
2 Track type: low grounding pressure, good passability, low center of gravity, good stability, strong adhesion, large traction, large cutting force, low speed, relatively poor flexibility, high cost, and easy to damage the road when walking.
4, loading and unloading methods:
1 Front unloading type: simple structure, reliable work, good vision, suitable for various work sites, and widely used;
2 Rotary type: The working device is installed on the turntable that can be rotated 360O. The side unloading does not need to be turned over, the work efficiency is high, but the structure is complicated, the quality is high, the cost is high, and the side stability is poor. It is suitable for the venue with smaller chivalry.
3 rear unloading type: front end loading, rear end unloading, high work efficiency, and poor safety of operation.
