PROBLEM TO BE SOLVED: To enhance the operating easiness of a working platform in the horizontal working control to move the working platform in the horizontal direction. SOLUTION: A control device 60 of an altitude working vehicle 1 is equipped with the working platform 7, a horizontal work control circuit 31 to control a boom 5 so as to move the working platform 7 in the horizontal direction along the reference line in accordance with the operation of a boom operating lever 12, and an operating lever 14 to revolve the working platform, wherein the arrangement further includes a lever operation sensing circuit 32 to sense the turning direction of the boom operating lever 12, a platform revolution stop sensing circuit 35 to sense the stop of the revolving motion of the platform 7, and a position calculating circuit 33 to calculate the position of the platform 7, and the tip of the boom 5 is moved horizontally in the direction along the original reference line without changing the reference line even if the turning direction of the platform revolution operating lever 14 has changed while the platform 7 is in revolution, and after sensing the stop of the platform 7 revolving, the tip of the boom 5 is moved horizontally along the reference line to be decided anew by the turning direction of the platform revolution operating lever 14 and the position of the platform 7.
