To develop a 6-wheel cart capable of being nested by lifting fixed casters from a ground plane without changing a total height of the 6-wheel cart.SOLUTION: A base plate 31 is placed on a cart frame 11 so as to be capable of rising and falling, and a connection member lifting mechanism 90 of a connection member 15 with fixed casters 22 attached thereon is provided in an upper part of a rear end member 13. When the base plate 31 is to be stood, a vertical cylindrical part 66 of the connection member 15 is lifted by rotation of a base plate installing member 32, and a fixed caster 23 is lifted by the rise of the connection member. With this arrangement, when the base plate is stood, nesting can be done without changing a total height, and when the base plate 31 is fallen, the fixed casters 23 are lowered to secure the straight advancing ability during conveyance.SELECTED DRAWING: Figure 1
【課題】六輪台車の全高を変えずに固定キャスターを接地面から上昇させてネスティングを行うことができる六輪台車を開発すること。【解決手段】台車フレーム11上に台板31が起伏可能に載置され、固定キャスター22を取付けた連結部材15の連結部材昇降機構90は後端部材13上部に設けられ、台板31を起立させるとき、台板取付部材32の回動により連結部材15の鉛直筒状部66を持ち上げ、連結部材の上昇により固定キャスター23を上昇させる。この構成により、台板を起立させたとき、全高を変えないでネスティングが行えるとともに、台板31を倒伏させるとき、固定キャスター23を下降させ、搬送時の直進性を確保した。【選択図】図1
