When welding, weld the inner joint instead of the outer joint to avoid being found. Playing with new paint is easy to be suspected. If you can't see the weld inside, play a small area inside.
Burn it better, polish it and then paint it. It's not obvious.
First find some irons, then the design height must be 4.2 meters, and then weld several irons together. After welding, it can be installed on the railing for manufacturing.
But ordinary trucks can't be changed into engineering vehicles because the chassis used is different. The engineering vehicle adopts special chassis, and the girder has stronger bearing capacity. It is also necessary to see whether there is a corresponding announcement that the engineering truck will be changed into a high-hurdle truck. If the published chassis model and parameters correspond, it can be changed.
The new standard load of 4.2 meters stipulates that the cargo size must be 18 meters long, 2.5 meters wide and 4 meters high, and the total weight of the cargo is 20 tons. Then, if the total height, width and total length of the goods from the ground do not exceed 4.2 meters, 3 meters or 20 meters, they may be fined below 200 yuan. The 4.2m blue van is a small car.
According to the length of trucks, the common models can be divided into 4.2m, 6.8m, 7.6m, 9.6m, 13m,17.5m. Among them, 4.2m, 6.8m and 7.6m are common light truck sizes, 9.6m is a medium truck, 13m is a heavy truck,/kloc-.
