The present invention relates to a high place work vehicle having a power cable twist prevention structure preventing a power cable connected to a boom from a power supply device from being twisted while the boom is rotating. According to the present invention, the high place work vehicle, having a boom support stand disposed on a carriage to support a boom, a fixing frame rotationally coupled to the boom support stand, and the boom fixed to the fixing frame, includes: a housing located on the boom support stand; a brush holder disposed in the housing and electrically connected to external power; a guide tube rotationally coupled to the housing and having an end portion located on the fixing frame; and a slip ring rotating together with the guide tube and electrically connected to the brush holder through the contact of the outer peripheral surface thereof with the brush holder to allow a power cable to pass through the guide tube and to be then connected to the boom, wherein while the boom is rotating, the twist of the power cable supplying the power to the boom can be prevented.
