FIELD: vehicles.
SUBSTANCE: construction and road machines, namely road rollers. In a device for connecting two tandem-type self-propelled road rollers with articulated frames and with transverse displacement of the rollers, the roller frames are hingedly connected by parallel beams to form a parallelogram, along which a hydraulic cylinder is installed diagonally.
EFFECT: expansion of the process capabilities of road rollers, increasing the accuracy of the thickness of the fresh layer of asphalt concrete rolled next to the already cooled coating layer and ensuring ease of compaction at curbs and manholes.
