This trailer combines three essential functions—automatic steering, extendability, and a detachable gooseneck—to offer a practical solution for long and oversized cargo transport. The automatic steering system helps the trailer move smoothly through narrow roads, job sites, and tight turns. It reduces deviation during cornering and makes daily operations more stable and predictable. The extendable structure allows the trailer to adjust its overall length quickly, giving transport companies more flexibility when handling cargo of different sizes. This helps reduce the difficulty often caused by extra-long loads and improves overall efficiency.

The detachable gooseneck makes loading and unloading more direct and easier, especially for heavy machinery, tall cargo, or equipment that cannot be lifted from above. Operators can drive the cargo directly onto the deck, saving time and reducing the risk of damage. When these three features work together, the trailer becomes a reliable tool for various heavy-haul tasks. It fits well with companies that frequently deal with long beams, machinery, construction equipment, or other oversized items. The overall design focuses on ease of operation, adaptability, and steady performance, making it a dependable choice for everyday heavy transport work.
