What is the length of a tractor head body?
2 Answers
According to regulations: the maximum length for a fence trailer is 14.6 meters, for a flatbed trailer is 17.5 meters, and for a container trailer is 16.4 meters. Introduction to tractor heads: A tractor head is another name for a trailer. A trailer can only form a complete transportation tool when combined with a tractor or other vehicles. Total weight of the trailer: A trailer whose total weight is borne by itself is called a full trailer, usually simply referred to as a trailer. Its characteristics include no independent power, independent load-bearing, and reliance on other vehicles for traction. A trailer is a type of non-powered road vehicle designed and technically required to be towed by a motor vehicle for normal use, intended for transporting people or goods, or for special purposes.
I've been driving trucks for many years, and the topic of vehicle length is quite important. The tractor unit, which is the towing part of the truck, typically ranges from 5.5 to 7 meters in length, averaging around 6 meters or slightly more. For instance, common models like the Volvo FH series are about 5.9 meters, while the Mercedes Actros is close to 6.3 meters. Domestic brands like Dongfeng can reach up to 6.5 meters. Length directly impacts the driving experience—longer bodies are more prone to scraping curbs or trees when turning in the city, especially for beginners who need more practice with reversing. I once encountered a situation in mountainous areas where a 7-meter truck almost got stuck on a narrow road; fortunately, I had planned the route in advance. Length also relates to safety and fuel consumption—longer trucks offer better stability but consume more fuel. With the trend toward new energy vehicles, lengths are now shrinking. When choosing a truck, consider your daily routes to avoid exceeding legal limits, as fines aren't worth it. I recommend fellow drivers try different lengths to find the right balance.
