Loader classification

Commonly used single bucket loaders are classified according to engine power, transmission form, walking system structure and loading mode.
1. Engine power:
(1) the power is less than 74kw as a small loader.
2. The power in 74~147kw is a medium loader
(3) power in 147~515kw for large loader
4. Power more than 515kw is a special large loader
2. Transmission form:
(1) hydraulic mechanical drive, small impact vibration, long lifespan, convenient operation, automatic adjustment between speed and load, generally used in large and medium loaders.
2. Hydraulic transmission: stepless speed regulation and easy operation, but it has poor startup ability. Generally, it is only used on small loaders.
(3) electric drive: stepless speed regulation, reliable operation, simple maintenance and high cost. It is generally adopted on large loaders.
3. Walking structure:
(1) tire type: light weight, fast speed, flexibility, high efficiency, no damage to road surface, high ground pressure and poor pass through, but widely used.
Crawler type: the ground specific pressure is small, through good sex, low center of gravity, good stability, strong adhesion, great traction, high ratio of cutting force, low speed, low flexibility, high cost, easy to damage the road when walking.
4. Loading and unloading methods:
1. Front unloading type: simple structure, reliable operation and good view. It is suitable for various operation fields and has wide application.
(2) rotary type: the working device is installed on a turntable with a rotation of 360 degrees. The side unloading does not need to adjust the head, the operation efficiency is high, but the structure is complex, the quality is large, the cost is high, and the side stability is poor. It is suitable for the smaller field.
3. After discharge type: front end loading, rear end unloading, high efficiency and safety of operation.
