Abstract
A three-level vehicle lift. The lift includes a four-post configuration in which each post includes a pair of vertically extending, side-by-side channels. Two platforms are provided. Each includes a carriage configured to engage a respective one of the channels in each post and a hydraulic actuator and lifting cable system disposed within the platform for lifting the platform. An actuation system having a single hydraulic pump is provided with a valve for selectively supplying hydraulic power to either an upper- or a lower-platform hydraulic circuit. The simplified lift and actuation system configuration reduces manufacturing, shipping, installation, and materials costs and complexities.
Claims20
A multi-level vehicle lift comprising:
- a plurality of vehicle platforms positioned in a vertically stacked arrangement to overlie one another, each vehicle platform configured to receive and support a vehicle thereon and vertically movable independently from each other;
- a plurality of leg assemblies spaced apart from each other and wherein each of the plurality of leg assemblies includes a number of vertically extending channels arranged side-by-side together, the number of channels in each leg assembly being equal to a total number of vehicle platforms in the plurality of vehicle platforms, each channel of each leg assembly being associated with a respective one of the plurality of vehicle platforms;
- and
- a plurality of carriages, each carriage engaging a respective one of the channels and coupled to and extending laterally from a respective vehicle platform associated with the respective one of the channels, the carriages being configured to move vertically along the respective channel to enable movement of the respective platform vertically.

- a plurality of vehicle platforms positioned in a vertically stacked arrangement to overlie one another, each vehicle platform configured to receive and support a vehicle thereon;
- a plurality of leg assemblies that each includes a number of vertically extending channels arranged side-by-side together, each of the channels being C-shaped to provide a pair of side walls and a back wall, and distal edges of the side walls including flanges extending at least partially toward one another, the number of channels in each leg assembly being equal to a total number of vehicle platforms in the plurality of vehicle platforms, each channel of each leg assembly being associated with a respective one of the plurality of vehicle platforms;
- and
- a plurality of carriages, each carriage engaging a respective one of the channels and coupled to the respective vehicle platform associated with the respective one of the channels, the carriages being configured to move vertically along the respective channel to enable movement of the respective platform vertically.
1 more element
A multi-level vehicle lift comprising:
- an upper-vehicle platform configured to receive and support a vehicle thereon;
- a lower-vehicle platform positioned vertically beneath the upper-vehicle platform and configured to receive and support another vehicle thereon;
- a plurality of leg assemblies spaced apart from each other and wherein each of the plurality of leg assemblies includes a first and a second vertically extending channel, the first and second channels of each leg assembly having a C-shaped cross-sectional shape that provides a pair of side walls and a back wall and being arranged side- by-side with adjacent side walls thereof abutting, the first channel of each leg assembly being associated with the upper-vehicle platform and the second channel of each leg assembly being associated with the lower-vehicle platform;
- and
- a plurality of carriages, each carriage engaging a respective one of the first or second channels and coupled to and extending laterally from the respective upper- or lower-vehicle platform associated with the respective one of the first or second channels, the carriages being configured to move vertically along the respective first or second channel to enable movement of the respective upper-vehicle platform or lower-vehicle platform vertically,
- wherein the upper-vehicle platform and the lower-vehicle platform are vertically movable independently from each other.
3 more elements
