The so-called vibratory roller train of the Hamm brand in the largest version on a scale of 1:50 is a toy model that sets standards from the point of view of model technology. The harmonious proportions of the rear section, also called the wasp waist, and the massive dimensions of the roller and the overall model in connection with a high model weight underline the special claim. Wheels with rubberized treads, true-to-the-original rims, rotating roller as well as an articulated joint below the cab.
