LT822-7 20 Ton Medium Crawler Type Excavator

Excavators, known as excavating machinery, is also an earthmoving machine that uses buckets to dig materials above or under the bearing surface and load them into transport vehicles or to the stockyard.

The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast. Excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator are operating weight (mass), engine power, and bucket capacity.
