c. DESIGN AND FABRICATION
1. Modular ramp units are to be built to shape, size, and finish as indicated on approved
drawings.
2. Ramp surface is to be continuous, without gaps, and shall have an extruded skid
resistant surface. Platform deck surface will be knurled to make skid resistance bi-
directional.
3. Ramps shall be constructed of interlocking 1
⅛” x 6” treads welded to the side rails.
4. All ramp sections shall have a 2” minimum curb height.
5. Top of all ramps must accept a full-width pivoting top adapter plate with a minimum
3” extension with a preformed angle between 8° and 12° with a skid resistant
surface.
6. Bottom of all ramps must accept a full-width pivoting bevel with a skid-resistant
surface from ramp to ground transition.
7. All fasteners shall be captured either on outside of ramp or underneath.
8. There shall be no fasteners protruding into the inner usable ramp or curb surface.
2.3 PLATFORMS
a. ENGINEERING
1. Platforms shall be designed to exceed 2009 International Residential Code (IRC) uniform
minimum distributed live load of 40 pounds per square foot (PSF) for balconies fire
escapes and stairs with a safety factor of 2 and a concentrated vertical load of 500 PSF.
The overall weight capacity of 850 pounds provides a minimum safety factor of 3.
b. MATERIALS
1. Platform sections shall be all aluminum construction from alloys 6005, 6061 or 6063.
c. DESIGN AND FABRICATION
1. Platform units are to be built to shape, size, and finish as indicated on approved drawings.
1. Platform surface is to be continuous, without gaps, and shall have an extruded skid-
resistant surface, knurled to make skid resistance bi-directional.
2. Platforms shall be constructed of interlocking 1
⅛ ” x 6” treads welded to the side rails.
3. Platforms shall be designed for variable height adjustment.
2.4 SUPPORT LEG ASSEMBLIES
a. ENGINEERING
1. All support assemblies shall be designed to support the ramp and platform sections
specified in sections 2.2 and 2.3.
2. Support assemblies shall be designed to hold the support tube (leg) vertical in all
locations regardless of slope.
3. Support tubes (legs) shall h ave a minimum wall thickness of .094”.
b. MATERIALS
1. Support assemblies shall be constructed of aluminum alloys 6005, 6061 or 6063 with
polymer feet.
2. All fasteners shall be grade 5 strength or higher with zinc plated or zinc chromate finish.
c. DESIGN
1. Support tubes (legs) of the support assemblies shall adjustable for variations in height.
2. All aluminum brackets shall be supplied for attachment of the ramps and/or platforms
to the proper support assembly.
3. All legs shall have a 7.375” x 7.375” square foot pad.
