Heavy load trailers are fundamentally designed as a framework equipped with a multitude of axle lines, each boasting an impressive load-bearing capacity, often extending up to a remarkable 40 tons per axle line. These trailers are engineered to handle substantial cargo loads and can be customized to accommodate varying load sizes and configurations. They are renowned for their adaptability, allowing for the connection of multiple trailers through the use of beams or module coupling, thereby creating expanded trailer configurations.
