Of course, primarily trailers are used in the construction. For the production of concrete or grout you need a lot of bulk materials – primarily sand and gravel. Without them you can’t build a house and do not repair motorway. It means that there must be transport, delivering them to the construction site. Ordinary trucks rarely cope in this task, and their load capacity is quite low. That is why dumpers are primarily used for these goals. But when their duty is not enough, then the use of the semi-trailer will be most welcome.
Furthermore, tent trailers are used to transport the industrial and consumer goods. In this case, they protect the contents from adverse environmental conditions, because often dust, moisture or wind are ready to damage the transported goods.
Another common type of semi-trailers is a container. This special machinery is engaged in the delivery of goods to the place of loading and unloading in the port, railway station, as well as to the destination.
