Most of the machines are packed in wooden case, but for some heavy machines, they'll be packed on specially-designed steel frame. Some small parts will be loaded into cartons.
Our factory is near Shanghai port, so most of the time, SHANGHAI port will be the loading port.
We are committed to providing customers all over the world with high-quality and stable vehicle testing equipment and providing one-stop services, including equipment selection, testing station layout design, equipment installation guidance, etc.
During the warranty period of the equipment, we will replace any non-human damaged parts free of charge. After the warranty period, customers need to purchase the required accessories, but we will provide permanent free online guidance to help customers solve their problems.
