Development History Of Excavators (2)

The first generation of excavators: the emergence of electric motors and internal combustion engines gave excavators advanced and suitable electric devices, leading to the birth of various excavator products. In 1899, the first electric excavator appeared. After World War I, diesel engines were also used in excavators, and this type of mechanical excavator powered by diesel engines (or electric motors) was the first generation of excavators.
Second generation excavators: With the widespread use of hydraulic technology, excavators have more scientifically applicable transmission devices, and replacing mechanical transmission with hydraulic transmission is a major leap in excavator technology. In 1950, Germany's first hydraulic excavator was born. Hydraulic mechanical transmission is the second-generation excavator.
Third generation excavators: The widespread application of electronic technology, especially computer technology, has enabled excavators to have automated control systems, and has also led to the development of excavators towards high-performance, automation, and intelligence. The emergence of mechatronics integration occurred around 1965, while the adoption of mechatronics technology on mass-produced hydraulic excavators was around 1985, primarily aimed at energy conservation. The electronicization of excavators is a hallmark of the third-generation excavators.
The excavator industry manufacturers can be roughly divided into four categories. More than 70% of domestic excavators are occupied by foreign brands, and domestic brands are still mainly small and medium excavators. However, the share of domestic excavators is gradually increasing, with a year-on-year increase of 3.6% in 2012.
