Claim Text:
1. A cantilever parking lift system operable to be positioned on a surface comprising: a vertically movable parking platform, first and second bases positionable on the surface, first and second columns extending vertically from the first and second bases, respectively, wherein the platform is positioned between the bases and columns; a lift mechanism comprising a vertically movable dynamic cross chain sheave assembly positioned adjacent the first column, a vertically movable static cross chain sheave assembly positioned adjacent the second column, a cross chain extending from the first base and functionally engaged with the dynamic cross chain sheave assembly and static cross chain sheave assembly and anchored at one end proximate a top portion of the second column, a lifting chain extending from the dynamic cross chain sheave assembly to an upper direction changing sheave proximate a top portion of the first column and to a lower direction changing sheave of a block assembly proximate a bottom of the first column, wherein the block assembly is housed in the first base, wherein the block assembly is movable along a length of the first base and operable to raise the dynamic cross chain sheave assembly, and wherein the cross chain extends beneath and transversely across the platform, and wherein when the lift mechanism is activated, the lifting chain is operable to raise the platform from one side only, and an opposite side of the platform is raised by interaction of the dynamic cross chain sheave assembly, static cross chain assembly and cross chain.
