The Guiness Book of Records confirms that Nicolas Industrie of France has built and developed the largest tractor trailer in the world, with the Tractomas TR 10×10.
It was built by the company in 2005 for super heavy duty jobs, like hauling tanker ship ballast and power generators over standard routes. With an empty weight of 40 tons, this monumental vehicle is capable of moving a convoy of about 700 tons. The model is still in service today.
