Skeletal trailers are specialized for the transportation of shipping containers. Their unique design consists of a lightweight yet sturdy frame that is specifically configured to carry standard - sized containers. The absence of a solid deck or sides reduces the weight of the trailer, improving fuel efficiency while maintaining high load - carrying capacity. Skeletal semi trailer feature twist - lock mechanisms that securely fasten the containers to the trailer, preventing any movement during transit. They are highly maneuverable, making them suitable for use in ports, intermodal yards, and on highways. In the global shipping and logistics industry, skeletal trailers play a vital role in the seamless transfer of containers between different modes of transportation, such as ships, trains, and trucks.
