How is the freight rate for semi-trailers calculated?

[GiannaLee]

Semi-trailer freight is generally charged based on a combination of cargo volume, distance, and weight. The total freight price = distance * standard truck load capacity * (ton/kilometer) price. Industry standards set the ton-kilometer price range between: [0.35~0.6] yuan. Relevant details are as follows: 1. Introduction: Semi-trailers are mainly used to transport large-volume, non-separable oversized cargo, such as excavators, etc. Fence-type trailers are more suitable for transporting perishable goods like vegetables and fruits, while box-type trailers are better suited for bulk cargo and moisture-sensitive valuable goods. 2. Difference: Unlike full trailers, semi-trailers have their axles placed behind the vehicle's center of gravity (when the load is evenly distributed) and are equipped with a coupling device that transmits horizontal or vertical forces to the tractor. Generally, full trailers have two axles, while semi-trailers have one. A semi-trailer refers to a vehicle that has no power of its own and shares the load with the main vehicle, relying on the semi-trailer for traction.
