How would I measure to know what size ramp I need
1456587
The directions on the Prairie View Industries website will tell you how to calculate length. All lengths claim to be able to handle 800 pounds, except for 12 foot, which only handles 600 pounds. However, I've never ridden it up the ramp -- I load the scooter manually. I would not feel safe riding up a portable ramp, even though I have the extension on the top for extra stability. However, I have known of someone who did ride into the van, and evidently had no problems.

Measure from the top of the stair at an angle that would be an acceptable incline for a wheelchair to be pushed. You want to allow for a steady incline -if it is too sharp if an incline you will never be able to push or pull an occupied wheelchair up the ramp

The answers given here are mostly correct. Allow foot of ramp length for every 2-3 inches of height to the area that the ramp will rest on in the vehicle, be it the bumper or the floor of you vehicle. The longer the ramp the easier it will be to drive or push someone up on. Be aware that for most people 1 foot of length to 3 inches of height is too steep and can be a struggle not only getting in but also out. This has to be balanced with the room available for storage of the folded ramp (half the over all ramp length) and the room that is available to use the ramp in, whether at your home or in a parking lot.

I believe the rule for steps is 1 foot of ramp for every 2 inches of height. But many push it to 3 inches due to space. I use a 6 foot ramp for the back of our minivan. Its a little steep for the power chair but it works. The 8 foot is just too long to store in the van.

I would say that they are a standard width (30") to accommodate a wheelchair or walker, but the length will depend on the height of the steps you are trying to get up as you don't want it to be to steep. 6' is good for your standard two step porch.

To determine the length of ramp needed:Measure the vertical rise from the ground to where the ramp will sit on the vehicle, stairs or threshold.Take that measurement (inches) and divide it by 3. This will determine the length of ramp needed for an unoccupied power chair.Example: 24 inches of rise requires an 8 foot ramp minimum (24 divided by 3).

I used mine on the bumper of my car, this is how i did it. I measured the height of the bumper and doubled it. My bumper is almost 36 inches, so I ordered the six foot one. I do not ride my powerchair up the ramp I walk next to it.

I believe there were directions on how to measure right in the description. I have a minivan, which measures approximately 28" from the ground to top of bumper. I ordered a 6' folding ramp that can be separated into two pieces, making it easier for me to use. My scooter is about 150#. I don't ride it up the ramp. I back the scooter up to the ramp and walk beside it. Hope that helps!

Go to the website, have a measuring tape available and follow directions. It works well.

If you have a 5" height from the floor to the house, then you will need the 5" X 34" ramp. my ramp runs from the deck up to the patio doors, which are 4" high, and fits perfectly. All I did was secure it with a screw in each corner. Each section raises the height by 1". I had a wooden wheelchair ramp built from the sidewalk up to my deck, and then put this ramp from the deck into the dining room, in place of a homemade plywood ramp.

you can do the math to determine the size. looking online you can easily tell you what the number represents and how to translate it into a size. for example, a 195/60R15 tire, is for a 15" rim. the 195 is the width in mm, and the 60, is a % of the width which makes the height of one wheel side wall. so for this tire, the height would be 15" + 2(195mm X 60%). It is twice because the wheel side wall is applied twice around the rim. so this equals 15" + 2(117mm) = 15" + 234mm. Now converting to the same units, it will be 15" + 9.21" = 24.21", brand new tire with no tread wear. Who knew math and algebra was actually useful in life. hope this helps. you can do the math to determine the size. looking online you can easily tell you what the number represents and how to translate it into a size. for example, a 195/60R15 tire, is for a 15" rim. the 195 is the width in mm, and the 60, is a % of the width which makes the height of one wheel side wall. so for this tire, the height would be 15" + 2(195mm X 60%).

For me, I measured the length of the ramp then took a 2x4 put it up against my vehicle then imagined how steep it is. The less steep the better. It also depends if your land is flat or sloped. My dog has since passed so we now use it as a training aid for agility.I hope this helps. Feel free to contact me again. Best wishes to you and you buddy!

I really don't know. I gave this as a gift to a beginner along with a ramp. Sorry!

The rise depends on how steep you slant it - left on its own, it's a flat piece of metal . I would say take a tape measure and place one end at the top of the steps, and then pull it down to the ground and then out, so the tape measure is at an angle you think you can easily manage. That will tell you how long a ramp you want to get.

Get a heavy duty one and measure the area between the outside wall and inside wall make sure you get one thats adjustable to that width.

Their website provides a way for you to measure for clearance. http://www.raceramps.com/40-inch-sport-ramps.aspx It's in the box that says "Do These Ramps Work for Me"

I looked through all the manuals I have and dimensions are not listed. I would have to measure which you could easily do yourself.

Also consider the length from the top step to the garage floor to verify that the ramp length is correct. If so, this ramp should work well.

Six steps may be a bit long. Will depend on your steps. I recommend that you measure it out. The ramp is plastic and should weather the elements well.

Hi Vega - The ramparts are just one part of the system. They attach to whatever material you want to use for the ramp. They're designed for dimensional lumber and this particular series suggests 2 x 8 lumber if I recall correctly (note - you need to confirm their recommendation and loading capacity). So....depending on your application you could use plywood depending on the load you will be applying to the ramps. I don't know what you're need is but I wouldn't feel comfortable with anything more than a push lawn mower or similar load. YMMV Good luck

Because of storage, handling, and real options with flexibility in use I never connected the two ramps. I store them stacked. Needed minimum space dimensions are 79"L x 15.5 " W x 5.5" deep. I hope this helps.

I just removed the dust cap and measured it for the correct size. Calipers are helpful but a good ruler will do in a pinch.

Using it on two steps would depend on the distance of the risers and treads of the steps. It would be hard to tell without measuring specifically. It could be estimated by laying a board the same dimension as the ramp over the steps to see if it cleared the steps.

My suggestion is to weigh the dimensions of the extend-a-room with your ramp. If your ramp is bigger, it should be just fine. If it's smaller, probably not.
