ABSTRACT:
Trailer unit for transporting constructional machines and the like, in particular tracked excavators, by means of a conventional truck or similar towing vehicle. The weight of the machine during transporting is resting in part on the towing vehicle and in part on the trailer unit (1, 2, 3, 4). The unit can be assembled on the basis of a bogie having at least two wheel and axle sets on an undercarriage (4). At either side thereof there is provided a supporting cradle (3) for carrying a portion of the tracks or wheels of the machine, said cardles being tiltable about a transverse, horizontal axis (5) between a lowered loading position and an elevated transporting position. The horizontal tilting axis (5) is located somewhat forwardly of the rear end of each cradle (3) at an area between the two ends (3A, 3B) thereof. The trailer unit makes possible a safe and comfortable loading and transportation of constructional machines and the like along the roads, by simple means which do not require large investments in transportation equipment.
