What are the load capacity specifications for flatbed trailers?

[StBrynlee]

Domestically common flatbed trailers are generally divided into two major categories, with a total of 6 load capacity specifications. Drawbar flatbed trailers: These are flatbed trailers with at least two axles. They feature one axle that can turn 180 degrees; they are connected to the trailer via a drawbar that allows angular movement; the drawbar can move vertically and is connected to the chassis, thus it cannot bear any vertical force. Semi-trailers with hidden landing gears are also considered drawbar flatbed trailers. General-purpose drawbar flatbed trailers: These are drawbar flatbed trailers used for transporting goods in an open (flatbed) or enclosed (box-type) cargo space. The body of the flatbed trailer is made of heavy steel, commonly referred to as: heavy-duty flatbed trailers. These are large, heavy-duty trailers with strong load-bearing capacity, also known as heavy steel flatbed trailers. Heavy steel flatbed trailers are generally used for industrial transportation of large-tonnage goods, for moving goods within factories, or for transporting goods on roads.
