To provide a concrete pump vehicle having high workability regarding installation of hydraulic piping.SOLUTION: A hydraulic oil outlet 322 though which hydraulic oil is supplied in a drive cylinder 32 of a concrete pump 3 is provided to a vehicle rear side. A valve unit 34 that switches a drive cylinder 32 to be driven among a plurality of drive cylinders 32, 32 is provided closer to a vehicle front side than the drive cylinder 32. Hydraulic piping 35 through which each of the drive cylinders 32, 32, a hydraulic pump, and the valve unit 34 are connected includes cylinder side piping 351 that is connected to the drive cylinder 32, and a valve unit side piping 352 that is connected to the valve unit 34. The valve unit side piping 352 is fixed to a lateral side 11 positioned below the drive cylinder 32 in a sub-frame 1.SELECTED DRAWING: Figure 6

    【課題】油圧配管の設置に関する作業性が良好なコンクリートポンプ車を提供する。【解決手段】コンクリートポンプ3の駆動シリンダ32において作動油が供給される作動油出入口322は車両後方側に設けられており、複数の駆動シリンダ32,32のうち駆動対象の駆動シリンダ32を切り換えるバルブユニット34は、駆動シリンダ32よりも車両前方側に設けられ、複数の駆動シリンダ32,32の各々、油圧ポンプ、バルブユニット34を接続する油圧配管35は、駆動シリンダ32に接続されるシリンダ側配管351と、バルブユニット34に接続されるバルブユニット側配管352とを含み、バルブユニット側配管352は、サブフレーム1における駆動シリンダ32の下方に位置する側部11に固定されている。【選択図】図6
