Classification Of Loaders

Commonly used single-bucket loaders are classified according to engine power, transmission form, travel system structure, and loading method.
1. Engine power: ① Power less than 74kw is a small loader. ② Power between 74 and 147kw is a medium-sized loader ③ Power between 147 and 515kw is a large loader ④ Power greater than 515kw is an extra-large loader
2. Transmission form: ① Hydraulic-mechanical transmission, small impact vibration, long life of transmission parts, easy operation, automatic adjustment between vehicle speed and external load, generally used in medium and large loaders; ② Hydraulic transmission: stepless speed regulation, easy operation, but poor startability, generally only used on small loaders; ③ Electric transmission: stepless speed regulation, reliable operation, simple maintenance, high cost, generally used on large loaders.
3. Walking structure: ① Tire type: light weight, fast speed, flexible and maneuverable, high efficiency, not easy to damage the road surface, large ground contact pressure, poor passability, but widely used; ② Crawler type: small ground contact pressure, good passability, low center of gravity, good stability, strong adhesion, large traction, large specific cutting force, low speed, relatively poor flexibility, high cost, easy to damage the road surface when walking.
4. Loading and unloading method: ① Front unloading type: simple structure, reliable operation, good vision, suitable for various work sites, widely used; ② Rotary type: the working device is installed on a turntable that can rotate 360°, and the side unloading does not require turning around, the operation efficiency is high, but the structure is complex, the weight is large, the cost is high, the side stability is poor, and it is suitable for narrow sites. ③ Rear unloading type: front loading, rear unloading, high operation efficiency, poor operation safety.
