Excavator and hook machine are the same kind of excavation machinery, and hook machine is also known as excavator, which is a colloquial term in some regions. There is no difference between the two.
Excavators, also known as excavators and hooks, are earthmoving machinery that excavates materials above or below the bearing surface with a bucket and loads them into transport vehicles or unloads them to a stockpile. The materials excavated by the excavator are mainly soil, coal, sand, and soil and rock after pre loosening.
From the perspective of the development of construction machinery in recent years, the development of excavators is relatively rapid, and excavators have become one of the most important construction machinery in engineering construction.
Extended data:
Purpose of excavator:
Excavator is a multi-purpose earthwork construction machine, mainly used for earthwork excavation and loading, as well as land leveling, slope repair, lifting, crushing, demolition, trenching, and other operations.
Therefore, it has been widely used in road construction such as highways and railways, bridge construction, urban construction, airport and port construction, and water conservancy construction. Therefore, excavators have the functions of bulldozers, loaders, cranes, and can replace these machinery to work.
Loading operations in quarries, tunnels, underground power plants, and stockyards; Excavating channels, canals, and dredging waterways; After replacing the working device, operations such as pouring, lifting, installation, piling, and soil compaction can be carried out.
