Classification of loaders

Commonly used single bucket loaders are classified based on engine power, transmission mode, walking system structure, and loading method.
1. Engine power: ① A small loader with a power less than 74kw. ② Medium sized loaders with a power of 74-147kw ③ Large sized loaders with a power of 147-515kw ④ Extra large loaders with a power greater than 515kw
2. Transmission form: ① Hydraulic mechanical transmission, low impact vibration, long service life of transmission components, easy operation, automatic adjustment between vehicle speed and external load, generally used in medium and large loaders; ② Hydraulic transmission: capable of stepless speed regulation and easy operation, but with poor starting performance, generally only used on small loaders; ③ Electric drive: stepless speed regulation, reliable operation, simple maintenance, and high cost, generally used on large loaders.
3. Walking structure: ① Tire type: lightweight, fast, flexible, efficient, not easy to damage the road surface, high grounding pressure, poor passability, but widely used; ② Crawler type: with low grounding pressure, good passability, low center of gravity, good stability, strong adhesion, high traction, high specific cutting force, low speed, relatively poor flexibility, high cost, and easy damage to the road surface during walking.
4. Loading and unloading method: ① Front unloading type: simple structure, reliable operation, good visibility, suitable for various work sites, widely used; ② Rotary: The working device is installed on a rotatable 360 ° turntable, and the side unloading does not require a U-turn, resulting in high work efficiency. However, the structure is complex, the quality is large, the cost is high, and the side stability is poor. It is suitable for narrow and small sites Rear unloading type: front-end loading, back-end unloading, high work efficiency, and poor work safety.
