The invention of the first excavator

The original excavator is manual, from the invention to the present has been more than 130 years, during which it has experienced the gradual development process from steam driven bucket rotary excavator to electric drive and internal combustion engine driven rotary excavator, the application of electromechanical hydraulic integration technology fully automatic hydraulic excavator.

 In 1951, the first fully hydraulic backhoe was introduced at the Poclain plant in France by Case, a pioneer in crawler and wheeled excavators. Thus creating a new space in the field of technological development of excavators. After the 1940s, hydraulic technology was applied in excavators, and due to the maturity of external technology, the crawler full hydraulic excavator that is common today was developed in the 1950s. 

The three most important parameters of excavators are: vehicle weight (mass), engine power and bucket capacity. In 1961, the Poclain plant reintroduced the TY45 wheel hydraulic excavator, making it recognized as the best excavator manufacturer in the industry. By the mid-1960s, Case had produced and sold six models of excavators in the United States. 

 In 1968, the Poclain plant was officially incorporated into Case, which further enhanced Case's R&D and manufacturing capacity for excavators. China's excavator production started late, from 1954 Fushun Excavator factory production of the first mechanical single-bucket excavator so far, has generally experienced surveying and mapping imitation, independent research and development and development of three stages.
