Large excavators are modified and equipped with special dredgers for large excavators. The EX1200 is a large excavator, and it took a lot of our personnel and steel to modify the large excavators's extension arm and ship. The ship is manufactured by a professional manufacturer and is used with our modified excavator long reach arms and excavator buckets to cooperate with professional transport ships in large-scale engineering construction and cleaning up river silt. It has an incomparable effect! !
