To provide a wheelchair capable of speeding up the motion of a hydraulic cylinder installed in the wheelchair and capable of taking measures to meet inability of a power unit.SOLUTION: The wheelchair includes: main stairs pivotally installed in a bodywork; sub-stairs that are freely slidable along the main stairs; an auxiliary step pivotally installed in the sub stairs; a tilt cylinder 6 that makes the main stairs undulate; a slide drive cylinder 11 that drives the sub-stairs in a direction projecting from the main stairs; a rotary drive cylinder 36 that rotates the auxiliary stairs; power units 51A, 51B that become a hydraulic fluid supply source; and hydraulic circuits 60A, 60B that selectively supply the hydraulic fluid from the power units to any one of the tilt cylinder, slide drive cylinder, and a rotary drive cylinder. To the hydraulic circuits, accumulators 70A,70B are connected and, there is a structure that can supply the hydraulic fluid from the accumulators selectively to any one of the tilt cylinder, slide drive cylinder, and the rotary drive cylinder.SELECTED DRAWING: Figure 5
【課題】梯子車に設けられた油圧シリンダの動作の迅速化や、パワーユニットの動作不能対策が可能な梯子車を提供する。【解決手段】車体に枢着された主梯子と、主梯子に沿って摺動自在な副梯子と、副梯子に枢着された補助ステップと、主梯子を起伏させるチルトシリンダ６と、副梯子を主梯子から突出する方向に駆動するスライド駆動シリンダ１１と、補助ステップを回動させる回動駆動シリンダ３６と、作動油供給源となるパワーユニット５１Ａ，５１Ｂと、パワーユニットからの作動油を選択的にチルトシリンダ、スライド駆動シリンダ、回動駆動シリンダの何れかに供給する油圧回路６０Ａ，６０Ｂとを備える。油圧回路にはアキュムレータ７０Ａ，７０Ｂが接続され、アキュムレータからの作動油を選択的にチルトシリンダ、スライド駆動シリンダ、回動駆動シリンダの何れかに供給可能な構成である。【選択図】図５
