This Architectural Drawing is AutoCAD 2d drawing of Suitcase Ramps details in AutoCAD, Dwg files. A suitcase ramp is one of the best ramps when it comes to portability. These are usually around four feet long and they can support around 800lbs. A suitcase ramp can lay directly on top of a small set of stairs so it's also useful for home use.
