Front end size standards for heavy trucks

Heavy-duty trucks have three main front-end size standards: length, width and height.

Length: The length of a heavy truck usually refers to the total length of the vehicle, including the length of the compartment and the tractor head. The length of heavy trucks in China is usually between 6 and 14 meters. Among them, 6-meter-long trucks are suitable for short-distance transportation within the city, while 14-meter-long trucks are more suitable for long-distance road transportation.

Width: The width of a heavy truck usually refers to the width of the compartment. The width of heavy trucks in China is usually between 2.5 and 2.8 meters. This width can meet the needs of most cargo transportation.

Height: The height of a heavy duty truck usually refers to the height of the compartment. The height of heavy trucks in China is usually between 4 and 4.5 meters. This height can meet the needs of most cargo transportation, and also can ensure the driver's vision and comfort.

Specific size standards for different types of heavy trucks
Tractor head: the standard size of the tractor head is 13 meters long and 2.5 meters wide. Different types of semi-trailers also have specific size regulations, for example, one-axle semi-trailer length of 8.6 meters, two-axle semi-trailer length of 10 meters, three-axle semi-trailer length of 13 meters, all types of semi-trailers height is 4 meters.
