Claims

[Scope of claim for utility model registration] (1) A roofed loading platform for a freight vehicle, which is formed so as to be surrounded in three directions by left and right side walls and a front wall, and which includes a lower half of the loading box that includes supports at its four corners. , a roof support column attached to each of the four corner columns so as to be movable up and down, a roof with a front wall and side walls supported by the roof support columns, and a roof attached to a vertical stile at the rear of the cargo box so as to be movable up and down; and a shutter-type door device that is stored directly under the roof, a link device that supports a floor plate disposed on the lower side of the lower half of the cargo box below the floor so that it can be horizontally raised and lowered, and the cargo A variable device for varying the roof height and floor height of a cargo vehicle in a freight vehicle, comprising a lifting device that raises and lowers the roof and floor plate using a single lift cylinder installed on the front wall side of the lower half of the box as a drive source. . (2) A first group of pulleys rotatably mounted near the upper ends of the front and rear columns inside the cargo box, and a group of pulleys rotatably mounted near the floor of the cargo box corresponding to each of the first pulley groups. a second group of pulleys, a roof support column vertically movably inserted into the front and rear columns, a roof fixed to the upper ends of these roof support columns, and connected to the front and left and right sides of the roof, respectively. a retractable canopy forming the front and side walls; a wire rope connected at one end to a part of the roof support column and wrapped around the first pulley group and the second pulley group; a lift cylinder for driving up and down, which is vertically arranged on the front wall side of the lower half of the box and whose rod is connected to the other end of the wire rope; and a lift cylinder erected on the front end side of the floor plate; The upper part is provided with a floor plate lifting member having a contact portion facing the upper end of the rod in the lift cylinder so that it can come into contact with the upper end of the rod during the ascent, and the roof and floor plate are moved up and down by the operation of the lift cylinder. A device for varying the roof height and floor height of a loading platform in a freight vehicle as claimed in claim 1. (3) The link device for raising and lowering the floor plate is arranged at the front and rear of the lower part of the floor plate, and the front link arm and the rear link arm are connected by a connecting rod, and the lift cylinder is used as a driving source. A device for varying the roof height and floor surface height of a cargo vehicle in a freight vehicle as claimed in claim 1, which is configured to function to maintain the levelness of a floorboard when the device raises the floorboard.
