You can build own wheelchair

                         

Wheelchair ramps can be a basic straight line from pavement to porch or more complex if they wrap or zigzag. How complicated you get will depend greatly on your skill level. But to design and build a wheelchairs ramp yourself essentially depends on two factors when you're in planning stage: your loved one's needs and the building the ramp leads up to.

 Steps for making wheelchair

1. First, one should have to measure up from the ground to find out how many inches the ramp will rise. As for every inch of rise, it will need one foot of run. To accommodate turning at the top of the ramp, up to 5 foot square landing must be laid out with batter boards and mason's lines. Each line must be leveled in order to apply the 3-4-5 triangle principle to square the corner. The line then slides along the batter board until the distance between two points (3 feet and 4 feet from the corner) is 5 feet.

2. Multiply the height of the steps, in inches, by twelve to find the length of the ramp you will need. A gradient of 1:12 is good for a ramp that is not too steep to climb in a wheelchairs  but is also not too long to be positionable in most corridors or outside.

3.Compare this calculated length with the free space available as determined by the second measurement in Step 1. If the calculated length is less than the free space, the ramp will work. If the length is greater than the free space, consider a slightly higher gradient or even a two-stage ramp that doubles back upon itself, to reduce the overall length.
