PROBLEM TO BE SOLVED: To perform comparatively accurate and stable operation control (an overturning prevention control) of a boom or the like during stoppage and traveling in a self-propelled vehicle for high lift work. SOLUTION: The self-propelled vehicle for high lift work is composed by mounting the boom 4 on a self-propelled vehicle so as to allow derricking and telescopic operations or the like and attacking a work platform 10 on a tip of the boom 4. It is provided with a moment regulating device 20a detecting an overturning moment acting on the vehicle from the boom 4 and the work platform 10 and regulating an operation of the boom 4 wherein the overturning moment exceeds an allowable moment, and a work range regulating device 20b detecting a position of the work platform 10 based upon the operation of the boom 4 and regulating the operation of the boom 4 wherein the detected position exceeds a preset allowable work range. When the vehicle is stopped, the operation of the boom is regulated by a moment regulating means and when the vehicle is traveling, the operation of the boom is regulated by a work range regulating means.
