A generator packaging frame comprises a lower frame, an upper frame, a plurality of first supporting arms and a plurality of second supporting arms. The plurality of first supporting arms can be respectively and detachably connected with the lower and the upper frames. Each second supporting arm detachably arranged on each first supporting arm. The plurality of second supporting arms can also be respectively and detachably connected with the lower and the upper frames. The distance between the lower frame and the upper frame when the first support arm connects to them is larger than the distance between those frames when the second support arm connects to them. The packaging frame has two structural forms. It can be used for packaging and transportation of the generator and also can be used as a supporting seat of the generator after being reassembled.
