MULTI-TURN FASTENER FOR TRANSPORTATION OF AUTOMOBILE SEMI-TRAILERS ON FLAT WAGONS Russian patent published in 2022 - IPC B61D45/00 B60P3/73 B61D3/18 B60P7/06 

FIELD: railway transport.

SUBSTANCE: invention relates to railway rolling stock, namely to devices for loading, unloading, securing and transporting automobile semi-trailers on a platform car. The multi-turn fastening means for transporting a semi-trailer on a flat car contains a semi-trailer support and a semi-trailer fastening means (1), consisting of side trusses, on which devices are placed for grabbing it by a loader, a locking bar and limiters for transverse movements of the semi-trailer relative to the longitudinal axis of symmetry of the semi-trailer fastening means, and made with the possibility of fastening on the stops of the platform car. The side trusses are connected to each other by metal sheets and a system of beams. On the locking bars of the side trusses there is an automobile stop (4). A pivot support (3) is located on the semi-trailer support, the displacement of which is prevented by the limiters of the semi-trailer support, which can be attached to the side beams of the platform car. The multi-turn fastening means allows transporting semi-trailers up to 17.5 m long and with a total weight of up to 36 tons on flat wagons.

EFFECT: invention expands the range of goods transported on platform cars, reduces the time of loading and unloading operations, reduces labor intensity and ensures the centering of the semi-trailer relative to the longitudinal axis of symmetry of the platform car.
