We have all heard about semi-trailers and semi-trailers. Now Xiaobian is giving readers a chance to introduce another heavyweight member of the semi-trailer family, the semi-trailer. This type of vehicle is a tanker truck that uses a tractor to connect trailers. It feels from the surface that the front and the main body are not connected. However, they are linked through a traction bridge, usually in accordance with the brand of the tractor. Named for the car, compared with the ordinary single-unit tanker , semi-hanging oil tanker can effectively improve the transport efficiency. In the same tonnage, reduce transportation costs and save fuel consumption.
There are several types of materials used for the tank body of semi-trailer tankers. When transporting general gasoline and alcohol products, the thickness is required to use 4 to 5 cm thick steel plates, and strong corrosion is required whenever sulfuric acid is transported. When it comes to sexual goods, it is necessary to use thick steel plates from 12 mm to 22 mm. After all, Xiao Bian feels that compared with strong acid products, gasoline Shen Ma can really accept that the total mass of semi-mounted oil tankers cannot exceed 55 tons, which is based on the quality of the car plus the quality of the goods. Now Xiaobian has come to recommend a semi-trailer with a large cargo capacity, which is the Dongfeng semi-trailer. The rated load capacity is 30,000 kg, which is 30 tons, and the tank volume is 44.99 cubic meters. The side protection and rear protection are all made of cold bay steel, and the threaded connection is used to ensure the tightness and safety of the tank. Buy it for practical inspection and observation.
Xiao Bian personally think that the semi-trailer and even the entire tanker market will have great potential in the future. With the continuous improvement of technology, tankers of oil tankers will have more and more durable and stronger. Material appears, and this will allow the tanker to be further improved in the type of transport. For example, some things that were not transported by the tanker can now be used to work. It seems that the former volatile and deteriorating chemical liquids can be transported with it. After several years of continuous improvement of the vehicle model, there will be more and more liquid products transported by tankers, making it more likely to expand. Operating range.
