What is the minimum slope for a ramp? Throughout this article series and in other documents you may see slope expressed as unit rise over unit run, such as 4:12 (4 inches of vertical rise in 12 inches of horizontal run), or you may see the same slope expressed as a percent (unit rise divided by unit run), or slope expressed in angular degrees. That is not a service ramp to me. In this document indicates inches and indicates feet. The Standards do A forklift driver should also comply with OSHA mandates for driving forklift on incline.
