Patent ID: 8286754

Claim:
A vertical lift platform assembly, comprising: first and second vertical support columns; first and second lifting brackets, each lifting bracket slidably received within one of the first and second vertical support columns and movable in a generally vertical direction; a lift platform operatively coupled to the first and second lifting brackets by first and second attachment configurations, respectively, each attachment configuration defining orthogonally disposed vertical, longitudinal, and lateral axes; at least one linear actuator operatively coupled to at least one of the first and second lifting brackets to translate the lift platform between at least a lowered position and a raised position; and wherein the first attachment configuration substantially restricts translational movement of the lift platform with respect to the first lift bracket along the vertical axis, the longitudinal axis, and the lateral axis, and wherein the second attachment configuration substantially restricts translational movement of the lift platform with respect to the second lift bracket along the vertical axis and only one of the longitudinal axis and the lateral axis.
