Semi-trailer

A **semi-trailer** (also known as a semi) is a type of trailer that has no front axle, relying instead on a tractor unit (a semi-truck or prime mover) to provide both motive power and to support a portion of its weight. This configuration allows for greater cargo capacity and maneuverability compared to full trailers. Semi-trailers come in a wide variety of designs, specialized for different types of cargo, including dry vans for general freight, refrigerated trailers (reefers) for temperature-sensitive goods, flatbeds for oversized or oddly shaped loads, and tankers for liquids and gases. The connection between the trailer and the tractor unit is made using a fifth wheel coupling. The trailer's design allows for efficient loading and unloading at docks and terminals, making it a crucial component of modern freight transportation and a backbone of global supply chains. Semi-trailers are widely used for transporting goods over long distances, contributing significantly to national and international trade. They are also known for the high availability of skilled professionals to transport goods around the world.
