A self-propelled elevating work platform comprises a first workbench, a second workbench and a third workbench enclosed and connected on a conical column from the bottom to the top sequentially. Each workbench comprises at least two supporting frames which can be connected to form a circular shape. Retractable elements are disposed between any two of the adjacent workbenches. An anti-slip element is disposed on an inner side of each of the supporting frames, and each of the anti-slip elements can move radially relative to the conical column. Thereby, when any two of the workbenches are fixed by the anti-slip elements, the other workbench can be driven by the retractable elements to move up and down. Each of the workbenches can be pulled or pushed in order to move up or down gradually, so that the worker on the third workbench can work on the surface of the conical column. |
