Structural features of Skeleton Semi Trailer

2025-08-29



Skeleton semi trailers are essential in the logistics and container transportation industries, designed specifically to carry shipping containers securely and efficiently. Their open-frame structure reduces weight while maintaining high durability, making them ideal for heavy-duty applications. Below, we break down the key structural features and technical parameters that define a high-quality skeleton semi trailer.

Key Structural Features:

  1. Modular Frame Design: The chassis is constructed from high-tensile steel, forming a lightweight yet rigid structure that distributes load evenly.

  2. Gooseneck and Front Section: Engineered for optimal weight distribution and compatibility with container locking mechanisms.

  3. Cross Member Arrangement: Strategically placed cross members provide support without adding unnecessary weight, enhancing flexibility for various container sizes.

  4. Corner Castings and Locking Systems: Standardized locking points ensure secure container attachment, complying with international safety standards.

  5. Suspension System: Typically equipped with air or mechanical suspension to absorb road shocks and protect cargo.
