Commonly used single-bucket loaders, according to engine, transmission forms, hiking system structure, loading of the different ways to classify.
Â
1, Engine power:
Capacity of less than 74kw small chargers.
Power in the 74 ~ 147kW medium loader
Power in the 147 ~ 515kW for large wheel loaders
Power is greater than 515kW for the big loader
2, Transmission Type:
Hydraulic – mechanical transmission, shock and vibration is small, driving pieces of a long life, ease of handling, speed and automatically adjusts between outer contain generally used in large scale multi-loader;
Hydraulic Drive: You can stepless speed control, the control rooms, but the start is bad, generally only a small loader on the applications;
Power Transmission: adjustable speed, reliable operation, easy maintenance, high cost, generally has a large loader.
3, walking structure:
Tire Type: Quality of light, fast, flexible, high efficiency, simple to the road, under great pressure damage, the poor, but was widely used;
Caterpillar: ground pressure is small, the good, low center of gravity, good stability, strong adhesion, traction, then cut into force, low speed, flexibility is relatively poor, high cost and easy road damage during the run.
4, loading and unloading method:
Front Discharge: simple structure, reliable, good vision is suitable for a variety of the work space, are widely used;
Rotary: Rotary operating device can be installed in the 360o's turn on stage, side need not resolve turning, operational efficiency, but the complex structure, quality, large, high costs and poor lateral stability, suitable for smaller rooms than the Xia.
