  • Patent number: 9174828
    Abstract: A portable, lightweight lift system employing one or more lift assemblies that counters effects of staging is disclosed. The lift system includes multiple lift assemblies, wherein each assembly may be connected to a lifting device such as a hydraulic or motorized jack. A lifting device comprises moving parts which are nested such that the difference in diameters of each of the moving parts is minimized. In one aspect, the lifting device is provided with an arrangement of seals such that, the working area of a smaller diameter tube is greater than the working area of a larger diameter tube causing the smaller tube to move before the larger tube.

  • Publication number: 20110116901
    Abstract: A fall prevention assembly for vertical lift systems for storage and in particular for parking motor vehicles, the lift system comprising a frame extending upward from a base and at least one platform that is raised vertically within that frame responsive to a lift mechanism upon which a vehicle is parked, the fall prevention assembly comprising a series of metal bars of sufficient size and strength to resist bending attached to the base of the unit and extending upward through a series of bushings mounted strategically on each platform usually at the corners. These bushings can be designed with ridges or teeth inside. As long as the platform or platforms remain level and in proper alignment with the lifting system and within the frame the bushings simply move up and down along the metal bars. In the case of the failure of a lifting means the platform or platforms would become unlevel or tilt and the bushings would bind upon the metal bar.

  • Patent number: 4674938
    Abstract: A frame supported by a base has at least an upper platform and a lower platform adapted to be nested together and supported at lower positions by the base. The upper and lower platforms are adapted to be moved upward for supporting vehicles above the ground. Lifting mechanism is provided for lifting the upper platform with a vehicle thereon to a first upper level sufficient to allow a vehicle to be located on the lower platform. Connecting straps extend between the two platforms such that when the upper platform is moved upward beyond the first upper level, the lower platform is pulled upward by the connecting straps. The lifting mechanism is adapted to move the upper platform with a vehicle thereon upward to a second upper level sufficient to pull the lower platform with a vehicle thereon to a level sufficient to allow a vehicle to be driven thereunder.
