What is the classification of the loader

1, the engine power: ① power less than 74kw for small loaders. ② power in 74 ~ 147kw for medium-sized loaders ③ power in 147 ~ 515kw for large loaders ④ power greater than 515kw for extra-large loaders

2, the transmission form: ① hydraulic - mechanical transmission, impact vibration is small, long service life of transmission parts, easy to operate, speed and external load can be automatically adjusted, generally used in large loaders; ② hydraulic transmission: stepless speed control, easy to operate, but poor start-up, generally used only in small loaders; ③ electric power transmission: stepless speed control, reliable, simple maintenance, Higher cost, generally used in large loaders.

3, walking structure: ① tyre: light weight, speed, mobility, high efficiency, not easy to damage the road, grounded than the pressure is large, poor throughput, but is widely used; ② tracked: grounded than the pressure is small, good throughput, low center of gravity, good stability, strong traction, traction, than the cutting force, low speed, relatively poor flexibility, high cost, easy to walk and damage to the road.

4, loading and unloading: ① front unloading: simple structure, reliable, good vision, suitable for a variety of operating sites, more widely used; ② rotary: the work device is installed in the 360 ° turntable, side unloading does not need to turn around, high operating efficiency, but the structure is complex, high quality, high cost, side stability is poorer for the more chivalrous small sites. ③ Back unloading type: front-end loading, back-end unloading, high operational efficiency, operational safety is not good.
