ABSTRACT:
A step-type vehicle lift is provided with a linkage assembly (20) and horizontally oriented barrier cylinder (228) that enables movement of a barrier plate (102) between a retracted position and a barrier position while the step/platform assembly (24) is in the step position. A hinge (800) that connects the barrier plate (102) to an outer platform member (103) and is provided with at least one laterally extending projection (810). When the step/platform assembly (24) is in the step position, and the barrier plate (102) is moved to the retracted position, the projection (810) on the hinge (800) engages a slot (114) formed in the top of one of a pair of rails (108) that support the step/platform assembly (24), thereby latching the step/platform assembly (24) in the stowed position. When it is desired to extend the step/platform assembly (24) into the platform position, the barrier plate (102) is raised to the barrier position, thereby disengaging the projection (810) from the slot (114) in the rail (108).
The barrier cylinder (228) is mounted to support plates (600) attached to the bottom surface (30) of the outer platform member (103) such that the barrier cylinder (228) is in a substantially horizontal orientation at all times.
