In this invention an elevator installs four door rack (6~9) to hang the supporting material (34). The door racks support the elevator (26). Each door rack is independently driven to hang the supporting material (34). If the slider (30) tilts when moving goods, then the hanging supporting 34 is rolled/ released to perform adjustment. This invented effect is to prevent that the slider tilts when the elevator is running, and only the vertical force is applied onto the door racks. |
