Separated by operation into open and shield-protected excavators. The former is known as the large all-cracked rock tunnel excavator, a collection of excavator sets, supported and scrapped, known as the “aeroplane carrier” and the “lord of the excavator” of engineering machinery。
The amplifier is a combination of amputation, shipment, walking, operation, etc. And is used mainly to cut under-well rock, coal or semi-coal rock alleys with random shapes. Although domestic dig-in machines are still some way from internationally advanced technologies, domestic technology levels have largely met domestic needs. Large- and medium-sized diggers continue to be innovative。
