Method and device for transferring freight units, preferably in combined road/rail freight traffic (interchangeable loader)

摘要

For decentralised transfer of heavy freight units in combined road/rail freight traffic various variants of vehicle-bound loading technology are known which are based on the side loader principle, the interchangeable frame principle and/or the displacement principle. These have the disadvantage of being too heavy themselves or not having sufficient manoeuvrability in the loading approach area of track systems and/or in the absence of the possibility of setting the load at the level of a carriageway. In order to avoid these disadvantages, an onboard loading technology which comprises a support frame which is arranged on the end sides of the road vehicle, can be displaced transversely with respect to the longitudinal axis of the vehicle and is provided with lifting columns, and which technology also comprises interchangeable running gear, and a bridge frame is provided which consists entirely or partially of the container of the freight unit and/or is a component of an enclosed logistic system. The transfer takes place by equalising the loading level in several loading stages, inserting the bridge frame into the loading track and alternately displacing the load and the bridge frame laterally with the aid of the interchangeable running gear. All the bending moments which occur during the transfer process as a result of loading are absorbed here by the bridge frame so that the onboard parts of the loading technology are only stressed by pulling forces and pressure forces. As a result, with a comparatively low deadweight of the loading technology arranged permanently on the road vehicle, a high ... Original abstract incomplete.
