The engineering vehicles made by Ganyu Machinery Factory are not good, have no credibility and cut corners seriously. I just sent one the other day. Don't listen to people in the factory. My custom-made carriage, with an agreed bottom of 3 mm and a side of 2 mm, was measured when I came back. The edge of 10 mm is less than 2 mm, which is a pothole factory. I hope that friends who buy cars will not be fooled. Even a diesel engine was not used. This is a cheating factory.
