Excavator, also known as excavator, is a kind of earth moving machinery that excavates materials higher or lower than the bearing surface with a bucket and loads them into transport vehicles or discharges them to the stockyard.
The excavator is composed of power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and other structures, and is mainly used for excavating soil, coal, sediment and other materials. The three most important parameters are operating weight, engine power and bucket capacity.
The excavator is a special engineering vehicle, which is composed of a rotating platform, a large shovel and a mechanical arm. Generally, it travels by tracks or wheels. Because of its special appearance, there are various names for it in the industry, such as strange hand, backhoe, excavator, etc. In view of the development of construction machinery in recent years, excavator has developed relatively fast, and has become one of the most important construction machinery in engineering construction. The most important three parameters of excavator: operating weight (mass), engine power and bucket capacity.
