According to the inquiry method, when buying a coal-pulling car, you must use the owner's ID card to register and go through the relevant formalities. If you buy with someone else's ID card, you may not be able to go through the relevant formalities or other problems. Therefore, it is suggested to use the owner's own ID card to buy a coal car.

Dump semi-trailer is suitable for the transportation of coal, ore, building materials and other goods, which can greatly improve the transportation efficiency of scattered goods and save unloading time and labor.
