In terms of structure, refrigerated tractors mainly include van-type refrigerated semi-trailers and refrigerated container semi-trailers, among which refrigerated container semi-trailers and unconventional refrigerated semi-trailers modified from second-hand shipping containers.
1. Refrigerated container semi-trailers are the main stream of mobility and flexibility
A refrigerated container semi-trailer, a refrigerated container is placed on a container slab or a skeleton car, and the refrigerated container generally has a specific refrigeration equipment. It is a very common refrigerated semi-trailer.
Compared with the van-type refrigerated semi-trailer, the price of this refrigerated semi-trailer also has advantages. Together, the refrigerated container is detachable and has high mobility. However, due to the different frame, the utilization factor of the whole vehicle's self-weight is not as good as the former. At one time, this type of vehicle needs to be affiliated with the company to obtain an operating license.
2. Second-hand sea cabinet modified refrigerated semi-trailer, low price and quick return
In the 1960s, the United States made clear containers, and the world trade pattern and form have undergone revolutionary changes. As the history of containers has been continuous for nearly half a century, the second-hand market is also very prosperous. The refitting of second-hand refrigerated shipping containers in my country has formed a relatively strict industrial chain and scale in some local areas in China. Refrigerated shipping container bodies, coolers, polyurethane panels, scrap metal, etc. are all useful. For example, the seaborne refrigerated containers are spliced and converted into refrigerated containers for land tractors.
