This 2,156 mm worm screw is designed to facilitate the vertical movement of the front section of the upper platforms. Its length provides a wide range of travel, which is essential for adapting to different vehicle types (saloons, SUVs, commercial vehicles) without compromising the stability of the structure. Made of steel, this screw is designed to withstand significant static and dynamic loads whilst resisting constant chassis vibrations. Its precision threading ensures a secure self-locking mechanism, preventing any risk of the platform accidentally lowering during loading.
