Standardization and Development of Road Freight Transport Vehicles

The standard “Limits of dimensions, axle load and mass for motor vehicles, trailers and combination vehicles” is one of China’s basic technical standard for vehicle management, which regulated the vehicle’s dimensions, axle loads and mass limit. It is applicable to all motor vehicles, trailers and combination vehicles. In order to promote the use of new structures and new technologies in vehicle production, China’s vehicle management and standardization management departments jointly carried out the technical amendment to GB1589. The revised version of GB 1589 added the type of center axle trailer. It perfected the length, axle load and total mass limit of the vehicle. This standard built China’s road freight vehicle modular system and solved the problems of the inadaptability between vehicle width and pallet’s size, the mismatching between tractors and semi-trailers, etc.
