A step-deck trailer, also known as a drop-deck trailer, is a type of flatbed trailer designed with two different deck heights. The front section is higher, while the rear section is lower, allowing for the transportation of taller cargo that may not fit on a standard flatbed trailer. This design helps to lower the center of gravity, improving stability during transport. Step-deck trailers are commonly used in the transportation of heavy equipment, machinery, and oversized loads. They typically have a maximum load capacity of around 48,000 pounds and can accommodate various types of cargo, making them a versatile choice in the trucking industry.
