This curb segment provides an orienting When driving down a ramp with an empty forklift, travel in reverse and keep the lifts forks pointed downward. Handrails on assembly area ramps can be discontinuous and lack extensions to allow access to seating and to permit crossovers within aisles. Here is an example: Ramp height: 18 inches (1.5 feet) Ramp length: 180 inches (15 feet) The formula applied here is height/length times 100 = degrees.

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. For example, a ramp with a height of 5 ft. and a length of 20 ft. has a grade of 25%: 5 ft. Rise / 20 ft. Run = 0.25 x 100 = 25% grade. Current code use is IBC2009.
