Wheels are installed at the lower ends of these pipes, and when loading cargo, the cargo is placed in a horizontal position.
When the carrier is not in use, the loading platform is pivoted to a fixed shaft so that it can be raised freely so that the loading platform collapses toward the pipe and becomes vertical.
