The Gooseneck detachable lowboy trailer is engineered for the efficient transportation of oversized and non-disassembled heavy equipment. It features a detachable gooseneck that separates from the lowboy. This design creates a loading ramp, allowing equipment such as bulldozers and excavators to be loaded and unloaded directly from the front, eliminating the need for a large crane. The hydraulic detachment system ensures effortless and precise operation, enhancing both safety and efficiency during loading and unloading. Constructed from high-tensile steel, the trailer offers exceptional structural integrity and a formidable 80-ton payload capacity. The low-profile deck design significantly lowers the center of gravity of the cargo, ensuring superior stability and safety during transit. By virtue of its unique separable structure, it perfectly solves the loading and unloading challenges of super-heavy machinery with limited climbing ability.
