Abstract
An automotive lift system includes a plurality of posts and yoke assemblies. The yoke assemblies are slidably coupled to the posts such that the yoke assemblies are vertically moveable between a lowered position and a raised position. A pair of runways are secured between a respective pair of yoke assemblies and are configured to engage an automobile to thereby communicate vertical movement of the yoke assemblies to the automobile. The yoke assemblies include a structural frame and a pair of contact assemblies configured to engage opposing surfaces of the posts. The contact assemblies include an axle assembly having a pair of contact members (e.g., rollers, sliders, etc.) that are configured to engage an interior or exterior surface of the post. The axle assemblies are rotatable and/or articulable about a vertical axis parallel with the posts to thereby maintain proper engagement between the posts and the pairs of contact members.
