PROBLEM TO BE SOLVED: To provide a high-place work vehicle that is capable of appropriately detecting a distance between a work bench and an upper structure and preventing the work bench from excessively approaching to the upper structure.SOLUTION: This high-place work vehicle is provided with: a projector 31 that is provided at one end of a work bench 20 and that radiates a light L in a direction roughly parallel to a floor surface at the prescribed height position of the work bench 20 from the floor surface; and a light receiver 32 that is provided at the other end of the work bench 20 and that can receive the light L radiated from the projector 31, and configured such that when the amount of light L received by the light receiver 32 becomes equal to or less than a prescribed level while the light L is radiated from the projector 31, the operation of a book 5 or the like in the approaching direction of the work bench 20 to an upper structure K is regulated, and an alarm is issued from an alarm device.SELECTED DRAWING: Figure 3

    【課題】上方構造物に凹凸が多い場合であっても、作業台と上方構造物との距離を適切に検出することができ、作業台を上方構造物に接近させ過ぎることを防止することができる高所作業車を提供する。【解決手段】作業台20の一方の端部に設けられ、作業台20の床面から所定の高さ位置において前記床面と略平行な方向の光Lを照射する投光器31と、作業台20の他方の端部に設けられ、投光器31から照射された光Lを受光可能な受光器32とを備え、投光器31から光Lが照射されているときに、受光器32が受光する光Lの光量が所定レベル以下となったときに、作業台20が上方構造物Kに近づく方向のブーム5等の作動規制、および警報装置による警報作動を行うように構成される。【選択図】図3
