A lowboy trailer is a heavy-haul transport platform engineered with a dual-drop deck architecture—consisting of a front gooseneck drop and a deep main-deck drop—to achieve ultra-low ground clearance for over-height cargo. Manufactured using Q345/Q550 high-tensile steel, the chassis integrates I-beam or box-beam longitudinal structures with automated submerged-arc welding to ensure high torsional resistance under extreme loads.

Equipped with 2–8 axle configurations, air-ride or mechanical spring suspension, and optional axle spreader systems, the trailer can distribute weight efficiently to comply with regional road regulations. The hydraulic detachable gooseneck (RGN) allows self-loading of large machines such as excavators, bulldozers, and industrial modules, while the reinforced main deck floor (checker plate or T-beam) ensures secure load bearing during high dynamic stress.
