The invention relates to a folding type suspension arm device supported by an electric pole. The folding type suspension arm device comprises a telescopic supporting rod body connected with the electric pole through a fixing seat, a horizontal suspension arm hinged to the upper end of the supporting rod body, an inclined supporting rod connecting the supporting rod body and the horizontal suspension arm and a driving mechanism arranged on the lower portion of the supporting rod body. A first traction rope set of the driving mechanism winds across a pulley at the upper end of the supporting rod body and a pulley at the moving end of the horizontal suspension arm and then is connected with a hoisting hook. The folding type suspension arm device supported by the electric pole has the characteristics of being safe and stable in structure, simple in erection process and the like; the existing electric pole is used for supporting the device, the device structure is thus simplified, and safety of the construction process is guaranteed.
