To prevent a swing leg wheel from derailing.SOLUTION: A cargo handling gear comprises a girder 21, a rigid leg 22 supporting the girder 21, and a hinged leg 23 supporting the girder 21. Both of the rigid leg 22 and the hinged leg 23 comprise wheels 25, 26 running on a rail R at their lower ends. The hinged leg 23 is connected the girder so that the upper end of the hinged leg 23 can be moved in the direction away from the girder 21 as well as it is oscillatably connected to the girder 21 around the axis along the direction of traveling on the rail R. For example, the hinged leg 23 is connected to the girder 21 by passing a connecting pin 231 through the slot 232 formed at its upper end part.SELECTED DRAWING: Figure 3
【課題】揺脚の車輪の脱輪を防止する。【解決手段】ガーダ21と、ガーダ21を支える剛脚22と、ガーダ21を支える揺脚23と、を備え、剛脚22と揺脚23は、いずれも、レールRを走行する車輪25,26を下端部に備え、揺脚23は、ガーダ21に対してレールRを走行する方向に沿った軸回りに揺動可能に連結されると共に、揺脚23の上端部がガーダ21から離隔する方向に移動可能に連結されている。例えば、揺脚23は、その上端部に形成された長穴232に連結ピン231を通してガーダ21に連結されている。【選択図】図3
