Summary:To provide a vehicle for high lift work capable of reducing the number of hydraulic components such as a hydraulic hose arranged on a high lift working device.SOLUTION: A vehicle for high lift work includes: an upper control valve 100 controlling supply and discharge of a hydraulic oil to a leveling cylinder 35; a hydraulic hose 121 supplying the hydraulic oil discharged from a hydraulic pump P to the upper control valve 100; and a hydraulic hose 122 returning the hydraulic oil discharged from the upper control valve 100 to a hydraulic tank T. The upper control valve 100 is provided on a tip part of a boom. The hydraulic hoses 121, 122 are inserted through the tip side of the boom from a base end side of the boom to be connected to the upper control valve 100.SELECTED DRAWING: Figure 4 【課題】高所作業装置に配索される油圧ホースなどの油圧部品点数を削減することのできる高所作業車を提供する。【解決手段】高所作業車は、レベリングシリンダ３５への作動油の給排を制御する上部コントロールバルブ１００と、油圧ポンプＰから吐出される作動油を上部コントロールバルブ１００に供給する油圧ホース１２１と、上部コントロールバルブ１００から排出される作動油を油圧タンクＴに戻す油圧ホース１２２とを備え、上部コントロールバルブ１００はブームの先端部に設けられており、油圧ホース１２１，１２２はブームの基端側からブームの先端側へと挿通されて上部コントロールバルブ１００に接続されている。【選択図】図４
