CONSTITUTION: Incline boards for carrying heavy equipment in a trailer are installed to the rear ends of the trailer in the carrying work of heavy equipment, with slant faces for the loading of heavy equipment. Parted incline boards of the incline boards are foldably connected with a foldable shaft(15) and the incline board is fixed to the rear end of the trailer rotatably around a rotating shaft(11). A rotating cam(12) is formed to the longitudinal center of the rotating shaft. A rotating cylinder for transmitting the rotating force is connected to the rotating cam.
