Add-a-Ramp Technical Specifications
Every effort was made to engineer and design Add-a-Ramp to ADA, ANSIA117.1, BOCA, Life Safety Code, OSHA, SBC, and UBC regulatory bodies. However, because local officials can establish special regulations you should review your installation with local authorities.
General Ramp Specifications
- Add-a-Ramp is designed for a slope no greater than 1:12 or one inch rise for every foot of ramp length.
- The clear width between handrails is 36 or 44 inches.
- All straight and curved ramp segments have a 2 inch high curb.
- All ramp segments, steps and landings have a molded in skid resistant surface. This surface is frequently used on marine products and diving boards.
- All straight ramps over 30 feet in length should have a level rest landing.
- All molded ramp components are manufactured from a high tech automotive grade fiberglass with a sandwich type construction for stiffness.
- All ramps are height adjustable to accommodate site conditions.
- Add-a-Ramp is designed to always have handrails.
- All molded ramps have a slight crown in the center to prevent water accumulation.
- The ramps are designed to support a live load of 100 LBS/SQF and a concentrated load of 300 LBS with a maximum load of 900 pounds per ramp section. Meets IBC specifications.
Landing Specifications
- Curved turn landings are always installed level and function as a rest or turn landing.
- Curved turn landings are designed for easy wheelchair manipulation and have an inside dimension of 36 or 44 inches.
- Square top and turn landings are 60 inches x 60 inches.
- A rectangular turn landing is constructed by joining two square landings and measures 60 inches x 120 inches.
- All landings have height adjustment to accommodate site conditions.
- The landings have a slight crown to prevent water accumulation.
- The ramps are designed to support a live load of 100 LBS/SQF and a concentrated load of 300 LBS with a maximum load limit of 900 pounds.
- All ramp segments, steps and landings have a molded in skid resistant surface. This surface is frequently used on marine products and diving boards.
- Top landings can have a higher handrail than the ramp or step handrail.
- The molded landings are manufactured from a high tech composite material with a sandwich type construction for stiffness.
Ramp, Landing and Stairs
- All handrails are continuous, even at switchback turns. Handrail junctions are made with a smooth round die cast aluminum connector designed for optimum user comfort.
- The clear space between any wall and Add-a-Ramp’s handrail is always greater than 1 ½ inches.
- Handrails are 38 inches.
- There is always an upper and lower handrail and the lower handrail can be located at any height during installation.
- Handrail termination at the steps and start ramp have a 12 inch diameter closed loop. This is an optional feature and most residential ramps are not required to use this part.
- Handrails butting up to the building are covered with a smooth, round top cap.
- Handrails are designed to not rotate within their fittings.
- Add-a-Ramp has a special outdoor mesh fabric that is used to fill the open space between the upper and lower handrail. This design is superior to typical fence slat constructions, because instead of a 4 inch minimum opening the mesh fabric has no openings.
- The handrail is 1.5 inches in diameter.
- Handrails are designed to support a concentrated load of 200 LBS applied at any point and in any direction and a uniform load of 50 LBS/SQFT applied in any direction, but not applied simultaneously.
- All handrails have an anodized finish for maximum oxidation protection and to prevent black oxide rubbing on on the user's hands.
