Abstract: A method for providing the lifting effect of a lifting transport trailer, wherein the lifting transport trailer comprises as main parts a frame (u) which has essentially a horizontal carrying planar surface (KT) or the like, a rotating wheel (PE) and a lever mechanism. According to the method, the factors on the quantity of the moments applying at the pivot point (P) between second frame lever (N) and the frame (u) are so selected that during shifting of the lifting transport trailer, the lifting transport trailer functions as a stiff body at least in two positions. In the first position, the sum of moments applying at the pivot point (P) applies in the first direction so that the lever mechanism formed by the lever frames (M, N) and at least one power transmission element (VE) is supported against the first limiter means (R1) in the frame (u), the carrying surface (KT) being in the lower position.
