The Production Of Excavator In China Started Late
The production of excavator in China started late, and the first bucket capacity was 1m³ from fushun excavator factory in 1954. Up to now, the mechanical single bucket excavator has generally gone through three stages, namely, mapping imitation, independent development, development and improvement.
In the early days of the founding of new China, the production history of excavators in China was started by surveying and mapping and imitating mechanical single-bucket excavators such as W501.W502. W1002 and W1002 of the former Soviet union in the 1930s and 1940s. Because of the need of national economic construction, more than ten excavator production plants have been set up successively. Since 1967, China has independently developed hydraulic excavators. The early developed products include the WYl00 model of Shanghai construction machinery factory, the w4-60 model of guiyang mining machinery factory and the WY60 excavator model of hefei mining machinery factory. Then came the WYl60 of the Yangtze river excavator factory and the WY250 excavator of hangzhou heavy machinery factory. They have taken a very important step for the formation and development of China's hydraulic excavator industry.
