The folding neck trailer innovatively adopts a folding gooseneck design. When the gooseneck is folded, the overall length of the vehicle is shortened, which is convenient for parking and transportation in a narrow space, effectively solving the problem of limited space. When transporting large goods, the gooseneck is unfolded, and the traction performance and stability of the vehicle are guaranteed. Its body structure is sturdy and uses advanced welding technology to ensure that all components are tightly connected and have strong carrying capacity. In addition, the folding neck lowboy trailer's suspension system has been carefully adjusted to adapt to different road conditions and provide a stable transportation environment for goods. It is suitable for scenes such as urban construction and logistics distribution that require high space utilization and transportation flexibility.
