Single bucket loader is commonly used among all kinds of loaders, it can normally divided into different sorts according to engine power ,transmission form ,walking system construct and loading method.
1  engine power:
1.1 power less than a 74kW : small bucket loaders.
1.2 power 74~147kw : medium bucket loaders
1.3 power 147~515kw: large bucket loader
1.4 more than 515kw : oversize bucket loads
2 drive type:
2.1 the hydraulic-mechanical transmission, impact and vibration of small, longer transmission life, and operational ease, speed and load are automatically adjusted, generally in large loaders in use;
2.2 fluid power: stepless speed regulating, easy manipulation, but of poor starts, usually used only on small loader;
2.3 electric drive: stepless speed control, reliable operation, easy maintenance, high cost, generally used in the loader.

3  walking system structures:
3.1 wheel loader: light quality, speed, flexibility, high efficiency, easy to damage pavements, high ground pressure, bad pass, but is widely used;
3.2 crawler loader : ground bearing small, through resistance, low weight and good stability, strong adhesion, high traction, than the relative difference of low cutting force, speed, flexibility, high costs, damaged pavement when walking.
4.  loading and unloading:
4.1  front discharge: simple structure, reliable operation, with a nice view, suitable for a variety of job sites, is widely used;
4.2 rotary: device mounted on a tilting 360 ° turntable, side unload without u-turn, high working efficiency, but the complex structure, high quality, high costs, poor lateral stability, applied to a smaller venue.
4.3  after discharge: front-end loaded, unloaded the back-end, high efficiency, job security is not good.
