LT850-7 50 Ton Large Crawler Excavator

Excavator, also known as excavating machinery, is an earthmoving machine that uses buckets to dig materials higher or lower than the bearing surface and load them into transport vehicles or unload them 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: operating weight (mass), engine power, and bucket capacity.
