Wheelchair Ramps - Part 4

Part 1 Part 2 Part 3

Building A Wheelchair Ramp

Except for the first section, which is embedded in the walkway or driveway, the sections should start and end at a support post. The outside stringers are then fastened to the upright supports using 3/8 or 1/2 inch carriage bolts or lag bolts. Always use washers.

The ends of the stringers should be cut at the appropriate angle for the slope of your ramp, as shown in Figure 15.

  1. If a straight through landing is required, it should be a minimum of 60 inches long and the same width as the wheelchair ramp. At a minimum there should be an upright support at all four corners of the landing.
  2. If a landing is required to change the ramps direction as a "U", it should be a minimum of 76 inches in width (two rams at 36 inches each plus the thickness of the support post), and 60 inches long and again there should be upright supports at all four corners, as shown in Figure 17.

If a landing is required to change the ramps direction as an "L", it should be a minimum of 60 inches wide and 60 inches long and again there should be upright supports at all corners, as shown in Figure 18.

  1. As with decks, there is no set design for wheelchair ramp railing construction. Figure 19 shows a simple but adequate railing using 2 x 2 uprights fastened to horizontal lumber between the support posts.
