ABSTRACT:
A painting booth includes doors at one end through which a vehicle can enter. A dual section ramp always contained entirely within the booth has a fixed grid section located at an end of the booth, opposite the door, and a moveable section connected to the fixed section and located just inwardly of the door. A filter layer is attached to the fixed section for filtering air circulating downwards there through. A protective grate located in a lower wall section, below the moveable section, provides lateral protection against the introduction of foreign matter into the booth. Powered jacks, located underneath the moveable section of the ramp actuates the moveable section between inclined and horizontal positions. A retractable prop connected to an underside of the moveable section supports the weight of a vehicle when the moveable section is retained in the horizontal position.
