Zusammenfassung: | Disclosed is a grader, comprising a frame (4) and a swing frame (10), wherein the swing frame (10) comprises a supporting beam assembly (1) and connecting parts (2, 3); the supporting beam assembly (1) comprises a plurality of beam members (11, 12, 13), and the ends of the plurality of beam members (11, 12, 13) are connected in sequence, so that the plurality of beam members (11, 12, 13) create a closed shape; the connecting parts (2, 3) are arranged on connecting ends of two adjacent beam members (11, 12, 13); and at least one of the connecting parts (2, 3) is rotatably connected to the frame (4), and at least the other of the connecting parts (2, 3) is rotatably connected to a driving part. Under the same bearing capacity, the supporting beam assembly (1) is smaller in structure, each beam has a bearing function, and the occupied area and the weight are smaller, thereby facilitating the implementation of making the whole vehicle lightweight.
