本発明は、いわゆるピギーバツタ方式によりトレーラを
鉄道輸送する場合の鉄道貨車への積載用トレーラおよび
その積載装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a trailer for loading onto a railway freight car and its loading device when the trailer is transported by rail using the so-called piggyback method.
従来、貨物を積んだトレーラをトラクタで牽引して路上
輸送し、そのトレーラを貨車に載せて鉄道輸送するいわ
ゆるピギーバックと称する輸送方式が知られており、ま
た鉄道貨車に対するトレーラの積載方法も従来種々提案
されている。Conventionally, a so-called piggyback transportation method has been known, in which a trailer loaded with cargo is pulled by a tractor and transported on the road, and then the trailer is loaded onto a freight car and transported by rail.Additionally, the loading method of the trailer onto a railway freight car is also conventional. Various proposals have been made.
ところが、従来は既存のトレーラを、そのまま貨車の床
面上に載せているため、重心が高くなり勝ちであり、し

ける不具合があった。また上記のようにトレーラを貨車
の床面上にそのまま載せた場合には、地上からの高さが
高くなるため、所定の高さ制限の下では、大きなトレー
ラを積むことができない等の問題があった。However, in the past, existing trailers were placed directly on the floor of the freight car, which tended to raise the center of gravity.Furthermore, the trailers were placed floating due to the rubber tires of the wheels and elastic members such as the suspension. There was a risk of the trailer shaking significantly due to vibrations from the freight cars during transportation, resulting in a lack of stability. In addition, if the trailer is placed directly on the floor of the freight car as described above, the height from the ground will be higher, so there will be problems such as not being able to load large trailers under specified height restrictions. there were.
本考案は上記の問題点に鑑みて提案されたもので、貨車
