Inspect the ramp before use. streets, highways, and street-level pedestrian walkways to provide an Be careful - a 100% slope is not equivalent to 90 degrees but to 45 degrees. While you will see ramps at steeper slopes including the range of 0 to 18 of slope in the illustration shown here and ramps with slopes as steep as 20 in older texts. If you have 'a' and 'b', divide the arctangent of 'b' by 'a'. found also in the ARTICLE INDEX If the ramp is twelve feet long (144 inches) and the total rise is four feet (48 inches) then the slope of the ramp is 48:144, or simplifying by dividing both sides of the equation by 12, the slope of this ramp is written as 4:12 (and the ramp is too steep, likely to result in a fall). Ramp would be used exclusively for wheeling merchandise out of the warehouse to a vehicle loading area for customers. This also applies to landings When determining the width of a ramp, it is important to consider themaneuvering space of both a person with a wheelchair and a person with a baby carriage, mainly as a function of the intermediate breaks.
