This creation is a kind of high bed carrier structure, the main carrier system has engine, two driving wheels of gearbox transmission and two free deflecting rollers, the dynamical system of engine is enabled to drive gearbox by entering power lever linkage belt idle wheel, so that driving wheel can be driven via the drive sprocket of gearbox, and tension adjustment wheel is engaged on chain, and it is equipped between free deflecting roller and wheel carrier and inserts solid pin, and two sides manipulation handle can draw transmission internal clutch distinctly to control the power of the side drive sprocket with and without person.本創作係一種高床式搬運車結構，主要該搬運車係具有引擎、變速箱傳動的二主動輪及二自由轉向輪，令引擎之動力係由入力桿連動皮帶惰輪而帶動變速箱，使得主動輪可經由變速箱的主動鏈輪所傳動，且鏈條上嚙合有張力調整輪，而自由轉向輪與輪架間設有插固之銷，且兩側操控把手可各別牽引變速箱內部離合器以控制該側主動鏈輪之動力有、無者。
