As a highly automatic H-beam production line, Heavy-duty steel production line sees reducing the use frequency of overhead crane as its subject. Through using automatic machines as roller conveyor, turning machine and conveying machine to conveying, turning and moving H beam during welding process, which greatly improved user’s production efficiency.
