Small hydraulic excavators have the advantages of wide applicability, multi-function, high return on investment, fast cost recovery, convenient transportation and transfer of work site. These advantages not only promote the rapid development of small excavator market, but also lead to higher and higher requirements for small excavators, such as high performance and high reliability, Low energy consumption and comfortable operating environment become the inevitable development direction of small excavator.
As an important supporting system of hydraulic excavator, electric control system is the core of improving function and technology development of small excavator. Due to the limitation of product cost, the configuration of electric control system of small excavator can not follow the design idea of large excavator.
