1. As an important construction machinery, excavators have changed the way of human construction. The powerful function of large excavators with high work efficiency. Excavator can complete many projects at a fast speed. it can also use various auxiliary equipment, such as hammer, fixtures etc.to carry out more complex operations and improve work efficiency.
2. Small excavators are flexible control and convenient maintenance, can adapt to different complex and harsh working conditions all kinds of pipeline foundation pit excavation, foundation engineering construction, public utilities, housing water leakage maintenance and other use range is very wide universal, is warmly welcomed by customers.
3. Various types of second-hand excavators are lower prices, good performance in the construction, mining, highway field to play a greater role, less investment but more returns for users.
