20160084432 | SELF-POSITIONABLE LIFTING DEVICE - A self-positionable lifting device includes a linkage that has mutually parallel first and second links. The first and second links each have two ends thereof pivotally connected to a loading component and a loading platform set, respectively, so that pivotally connected points connecting the first link and the second link to the loading component and the loading platform set jointly define a parallelogramic area. The self-positionable lifting device further includes a damping mechanism that has a damper and a switch. The damper is provided between the linkage and loading component. The switch controls the damper to extend or retract by means of a control cord, the loading platform set can horizontally move in multiple directions with respect to the loading component as a result of relative pivotal movements between the first and second links. After adjustment, the loading platform set can be positioned. | 03-24-2016 |
