PURPOSE: A trailer for cargoes is provided to load a cargo with a narrow wheel by moving a footstool to the outside or inside of a loading bed based on the width of the cargo. CONSTITUTION: A trailer for cargoes comprises a loading bed (10), a crossbar (20), a slider (30), a footstool (40), a fastener (50), and a movable cylinder (60). The loading bed is connected to a running vehicle. Both sides of the loading bed are equipped with expansive units to be expanded based on the width of a cargo. The crossbar is fixed to the rear end of the loading bed in the width direction. The slider moves in the longitudinal direction of the crossbar with the footstool. The footstool connects the top of the loading bed to the ground to guide an electric vehicle or heavy equipment to the loading bed. The fastener rotatably joins the footstool to the slider. The fastener is moved in the longitudinal direction of the slider. The movable cylinder applies driving power to the footstool and moves the footstool by expanding. |
