Which is more widely used, semi trailers or full trailers? What are the strengths and weaknesses?
The full trailer has no leg, but it has a small trailer under the tractor, which can swing from side to side, and the tow truck and tow head are connected by dragging hook.It must be a wide distribution of semi-trailer, or the proportion of 95:5 in the country.
Put it simplyThe semi trailer has a leg, and the tow head can leave the semi-trailer through the traction pin and the pull head, and when the tractor head leaves the semi-trailer, the semi-trailer is supported to the ground through the support leg.
I'm not sure why you're asking this question. In China, they are basically semi trailers. They have been seen abroad (in Thailand and Australia), or I have seen the older ones in my country when I was a child. This is based on the drag head. As far as we are concerned about the "semi - hung" and "all hung", the semi - hanging is better than the whole one, and the light can be light.
