High-altitude operating vehicle

The invention provides a high-altitude operating vehicle. The high-altitude operating vehicle comprises a vehicle body, an extending arm supporting base and an extending arm. The extending arm supporting base is arranged on the vehicle body. The extending arm is arranged on the extending arm supporting base and comprises a first rotating arm, a second rotating arm, a telescopic arm and an operating cabin. The first rotating arm is rotationally arranged on the extending arm supporting base and can rotate in the first vertical plane. The second rotating arm is rotationally arranged on the first rotating arm and can rotate in the second vertical plane. The first vertical plane and the second vertical plane are located on the same plane. The telescopic arm is arranged on the second rotating arm in a telescopic manner. The operating cabin is arranged on the telescopic arm. By means of the technical scheme, the problem that the size of a high-altitude operating vehicle in the prior art is too large so that the operating vehicle cannot adapt to a narrow street can be effectively solved.
