A semi-trailer is a type of trailer that is attached to a truck via a fifth wheel. Semi trailers are typically used for transporting a variety of goods, including heavy and bulk materials. They are available in multiple configurations, such as flatbeds, tankers, and lowboy trailers, making them versatile for various transportation needs. These trailers consist of one or more axles and a platform designed for load-bearing. Semi trailers offer excellent load capacity, robust durability, and the ability to transport goods over long distances. Their advantages include easy attachment to prime movers, ensuring efficient and flexible transport for a wide range of industries, including logistics, construction, and agriculture. 

These trailers are engineered to withstand the rigors of both short and long-haul routes while maintaining cargo safety and stability. Semi trailers are suitable for transporting everything from dry goods and liquids to heavy machinery. Moreover, their durability, low maintenance costs, and high load capacity make them a reliable choice for companies looking to optimize their transportation fleets.
