Flatbed trailers load can vary considerably in max and physical dimensions. While flatbeds are designed to carry a load of almost any size, roads are not so flexible, so the maximum standard width and height for cargo on a flatbed trailer is 8’-6”. Flatbed trailers can carry a load no heavier than 48,000 pounds, and most trailers are between 48’-0” and 53’-0” in length. Any cargo wider than 8’-6” would be classed as a wide load or heavy haul. Loads over 12′ wide require an escort vehicle in most states. Additionally, over-width shipments can also only be moved during daylight hours, thus restricting the speed at which your shipment can be delivered. For cargo over 8’-6” in height, consider a drop-deck or double-drop flatbed trailer load. A drop-deck or step-deck trailer can accommodate cargo up to 10’ in height, while a double-drop flatbed can cope with cargo as high as 12’.
