Crawler Excavator

Crawler hydraulic excavators are earthmoving machines that use buckets to dig up material above or below the bearing surface and load it into a transport vehicle or unload it into a stockpile. The excavated materials are mainly soil, coal, sediment, and pre-loosened soil and rock. From the perspective of the development of construction machinery, the development of excavators is relatively fast, and excavators as one of the most important construction machinery models in engineering construction, its correct selection is more important.Common excavator structures include, power unit, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. From the appearance, the excavator is composed of three parts: a working device, an upper turntable, and a walking mechanism.
