A method for coupling a self-propelled truck with a carrying truck, comprising the steps of: providing a female engagement means at a rearward side of said self-propelled truck; providing a male engagement means at a forward side of said carrying truck; wherein said female engagement means is so formed as to have an engagement base portion for allowing engagement with said male engagement means and retaining the same therein, and a pair of right and left opening means disposed symmetrically relative to and continuous with said engagement base portion; defining a curved point in a path along which said self-propelled truck moves in a forward direction; and locating said carrying truck adjacent to said curved point, such that said male engagement means provided at the forward side of said carrying truck is positioned at a path along which one of said right and left opening means is to be displaced when said forwardly moving self-propelled truck turns at said curved point, whereby, when said self-propelled truck turns at said curved point, said female engagement means is subject to a swerving motion in respect of a curved line at said curved point, bringing said one of said right and left opening means towards said male engagement means of the thus-located carrying truck, so that said male engagement means is caught in said one of said right and left opening means, and engaged and retained in said engagement base portion of said female engagement means.
