How do common loaders work?(1)

The working principle of the loader mainly includes the power system, mechanical system, hydraulic system and control system work together.

Loader power is generally provided by the diesel engine, diesel engine has a reliable, fuel economy and other characteristics, in line with the requirements of the loader's poor working conditions, 

load variable. Mechanical system mainly includes traveling device, steering mechanism and working device. The hydraulic system transforms the mechanical energy of the engine into hydraulic 

energy through the oil pump, and then transmits it to the oil cylinder and so on to transform it into mechanical energy. The control system controls the engine, hydraulic pump, multi-way reversing 

valve and actuators.

The working device of the loader consists of bucket, arm, connecting rod, rocker arm, etc. The turning of the bucket and the lifting and lowering of the arm are hydraulically operated. The working 

efficiency of the loader is high, for example, the average shift production capacity of the loader with bucket capacity of 5~8m³ can reach 3500~4000 tons.

In the market, common loader models are categorized by engine power, transmission form, travel system structure and loading mode. The power of small loaders is less than 74kw, the power of 

medium-sized loaders is between 74 and 147kw, the power of large loaders is between 147 and 515kw, and the power of extra-large loaders is more than 515kw. Commonly used models of loaders 

include ZL30C, ZL40B, ZL45A, ZL50C, etc., which are of different rated power and bucket capacity and suitable for different operations. These models have different rated power and bucket capacity,

 which are suitable for different operational needs.
