An improved elevator platform structure of the type that includes a framework and a horizontally disposed elevator platform, the platform being raised and lowered by hydraulic rams connected to the framework. The elevator platform includes a pivotable ramp at one edge thereof, the pivotable ramp being biased into a horizontal attitude in which the elevator platform may be loaded or unloaded over that ramp, and into a vertical attitude at which that ramp functions as a stop as the platform is raised or lowered. A reciprocable safety foot structure is connected to the framework, and is automatically movable into an active position underneath the pivotable ramp when the platform is in its uppermost position. This safety foot structure insures that, as the platform is lowered from its uppermost position, the ramp will be pivoted from the horizontal attitude toward the vertical attitude, thereby locating the pivotable ramp in its stop position.
