1 Answers
According to regulations, the height of a semi-trailer must not exceed 4.2 meters. As stipulated in Article 54, Paragraph 1 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China: The load height of heavy and medium-duty trucks and semi-trailers shall not exceed 4 meters from the ground, while container-carrying vehicles shall not exceed 4.2 meters. Below is an introduction to semi-trailers: 1. Introduction: A semi-trailer is a trailer with axles positioned behind the vehicle's center of gravity and equipped with a coupling device that transmits horizontal and vertical forces to the tractor. It is a heavy-duty transportation vehicle connected to the semi-tractor via a kingpin. 2. Features: Compared to "monocoque" vehicles, semi-trailers can significantly improve the comprehensive economic benefits of road transportation. Transport efficiency can increase by 30-50%, costs can be reduced by 30-40%, and fuel consumption can decrease by 20-30%. 3. Uses: Semi-trailers are primarily used to transport large, indivisible cargo, such as excavators. The flatbed type is suitable for hauling perishable goods like vegetables and fruits, while the van type is ideal for bulk cargo and moisture-sensitive or high-value goods.
