Excavators, also known as excavators, are earth-moving machines that use buckets to dig up materials above or below the bearing surface, load them into transport vehicles or unload them into the yard.

The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight, engine power and bucket capacity.

The production of excavators in China started late. Since Fushun Excavator Factory produced the first mechanical single bucket excavator with bucket capacity of 1m3 in 1954, it has gone through three stages: mapping imitation, independent research and development, and development.

In the early days of the founding of New China, the production history of excavators in China began with the mapping and imitation of mechanical single bucket excavators such as W50 1, W502, W 100 1 and W 1002 of the former Soviet Union in the 1930s and 40s. Due to the need of national economic construction at that time, more than ten excavator manufacturers were established successively. From 65438 to 0967, China independently developed hydraulic excavators.

The products successfully developed in the early stage mainly include WYl00 from Shanghai Construction Machinery Factory, W4-60 from Guiyang Mining Machinery Factory and WY60 excavators from Hefei Mining Machinery Factory. Followed by the Yangtze River excavator factory WYl60 excavator and Hangzhou heavy machinery factory WY250 excavator. They have taken an extremely important step for the formation and development of the hydraulic excavator industry in China.

By the end of 1980s, there were more than 30 excavator manufacturers in China, producing more than 40 models. Small and medium-sized hydraulic excavators have formed a series, with bucket capacity of 0. 1 ~ 2.5 m3 and 12, with more than 20 models. They also produce 0.5 ~ 4.0 m3, 10 m3 and 12 m3 mechanical transmission single bucket excavators, 1 m3 tunnel excavators and 4 m3 long arms for large mines.

1000m3 /h bulldozer, etc. Marine hydraulic excavators with bucket capacity of 0.25m3 and amphibious excavators with bucket capacities of 0.4m3, 0.6m3 and 0.8m3 have also been developed. But generally speaking, the production batch of excavators in China is small and scattered, and the production technology and product quality are far behind the international advanced level.

Introduction of excavator

Excavators, also known as excavators, are earth-moving machines that use buckets to dig up materials above or below the bearing surface, load them into transport vehicles or unload them into the yard.

The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight, engine power and bucket capacity.

At first, the excavator was manual, and it has been more than 30 years since its invention to 20 13. During this period, it has experienced a gradual development process from steam-driven bucket rotary excavator to electric-driven rotary excavator and internal combustion engine-driven rotary excavator, and then to fully automatic hydraulic excavator with electromechanical and hydraulic integration technology. The first hydraulic excavator was successfully invented by Boquelin Factory. Due to the application of hydraulic technology, in the 1940s, there appeared a hanging excavator equipped with a hydraulic backhoe on tractors. 195 1 year, the French Poquelin factory launched the first full-hydraulic backhoe excavator, thus creating a brand-new space in the field of excavator technology development. In the middle and early 1950s, traction hydraulic excavator and crawler hydraulic excavator were successfully developed. The original trial-produced hydraulic excavator used the hydraulic technology of aircraft and machine tools, and lacked hydraulic components suitable for various working conditions of the excavator, so the manufacturing quality was not stable enough and the supporting parts were not complete. Since the 1960s, hydraulic excavators have entered the stage of popularization and vigorous development, and the manufacturers and varieties of excavators in various countries have increased rapidly, and the output has soared. During the period of 1968- 1970, the output of hydraulic excavators has accounted for 83% of the total output of excavators, which is close to 100%.

The first generation of excavators: the emergence of electric motors and internal combustion engines made excavators have advanced and applicable electric devices, so various excavator products were born one after another. 1899, the first electric excavator appeared. After World War I, diesel engines were also used in excavators. This mechanical excavator driven by diesel engine is the first generation excavator.

The second generation excavator: With the wide application of hydraulic technology, excavators have more scientific and applicable transmission devices, and hydraulic transmission instead of mechanical transmission is a great leap in excavator technology. The first hydraulic excavator in Germany was born in 1950. Hydromechanical transmission is the second generation excavator.

The third generation excavator: The wide application of electronic technology, especially computer technology, makes the excavator have an automatic control system, and also makes the excavator develop in the direction of high performance, automation and intelligence. The germination of mechatronics took place around 1965, and the electromechanical integration technology was adopted on the hydraulic excavator mass-produced around 1985, and the main purpose at that time was to save energy. Electric excavator is the symbol of the third generation excavator.

Excavator manufacturers can be roughly divided into four categories. More than 70% of domestic excavators are occupied by foreign brands, and domestic brands mainly dig small and medium, but the share of domestic excavators is gradually increasing, with a year-on-year increase of 3.6% in 20 12.
