    Anyone have any car ramp designs or plans?

    Gday, as the title suggests, Im after some car ramp plans that I can make myself.

    Basic ideas are that I want to make the platform section around 350mm high, 300mm wide (across the tyre) and 500mm long (from front of ramp to back) and approximately 1200mm long ramp section which is detachable, so the vehicle would be left on the platform in the air with no ramp.

    Just not sure on actual dimensions, stability, materials etc, so any guidance would be much appreciated thanks.

    oh I forgot to add that my welder specs are:

    Transmig 165

    Maximum open circuit voltage: 34vdc
    welding arc voltage: 15-21vdc,
    Output current: 30-165 amp

    and I have been using .9mm (.035") flux core wire:
    E71T-11 (AWS A5.20) on DCen


    TYPICAL WELD METAL CHEMISTRY* (Chem Pad):
    Weld Metal Analysis Self-Shield 11 AWS Spec

    Manganese (Mn) 0.38 1.75
    Silicon (Si) 0.18 0.60
    Phosphorus (P) 0.006 0.03
    Sulphur (S) 0.004 0.03
    Aluminum (Al) 1.56 1.80
    Note: AWS specification single values are maximums.

Even so, it only gets used on the flat concrete floor & I am careful to stay as clear of the car as possible until the stands are slid in place, just in case. The "Z" only weighs 1,400 lbs. at this point, but we've had my son's 95 Camaro up on the stands to do exhaust work.
    @pro70z28 Thank you very much for the very inspirational photos much appreciated mate!
    What you have been able to show in a few photos is that this is not as difficult as some of the poster's here have made out.

    Obviously you are a constructor who has not become so extremely concerned about the trivial crap (and other people's abilities to weld) that appears to have confused some people into NOT sharing their knowledge!

    I commenced my ramps project, though it was placed on hold because of other commitments, 2 family funeral's, as well as my travel away from home, but I am planning to get them finished in the next few weeks, and will certainly place photos up here afterward!

I always hoped to come across a real cheap vehicle ramp from a used car lot or something - at least until I had a place I could get a lift. Your idea is a much more reasonable solution to get the car high and not take up too much room when it's not being used.

    Great idea, and great looking car too!
    @TravisT, There is your reason, idea, and (as I was originally seeking) the vision to get constructing & I agree, great idea and car!

    @woodtick007, We use 240vac 50hz here, though over the years I have also welded with direct 12vdc arc, 24vdc arc and 36vdc arc.

    I am welding now using my 240vac inverted to

    Also, these mini spool mig guns are just awesome and the welds, well they are comparable to the BIG professional units I have used.

    I made them out of angle because I had an abundance of it given to me awhile back.
    (I bolted the wooden parts on with carriage bolts, as I couldn't get welds to hold either)
    That's a really cool idea. This is something I would throw together and use until I have a garage with a lift.

    One question though - what do you use to get the car high enough to get the stands under? Can't tell the exact height, but it looks like it would be higher than a typical jack could reach.

    Bob, methinks that the manufacturing of ramps and selling them would be considerably different to the selling of PLANS for someone else to construct the ramps.

    Basically, if an architect drew plans for a building design to what you want, and an engineer approved the design, then YOU built it yourself, and omitted parts from teh design, or instead of using steel bolts you used plastic bolts, and then it fell down and killed someone, do you think there would be any chance that any court would allow a law suit from you (the constructor)???


    GET REAL PEOPLE!!!!!

    Geez, I can go and purchase all the engine parts from my local store to build almost any engine I want, but if I did that and forgot something, or changed it from the engineered design, would they support any breakage claim??? NO!

    Some interesting information regarding ramp designs

    Did you know that there is engineering methods that can be used to increase safety factors?

    If the base of a ramp or platform is at least 1.2 times the height of a ramp then it increases stability, thus making it much less likely to tip over (As you see with circus platforms for elephants)

    If the height is 12" (300mm near enough) then your ramp should have a base of at least 14" (360mm) and obviously if you taper the platform height smaller than your footing then it will also increase stability.

    Hence the reason why my platforms (at this stage) should be around 12" (300mm) high, 12" (300mm) wide by 17.75" (450mm) long at the top and 13.75" (350mm) wide by 19.7" (500mm) long at the bottom.


    Constructing with the taper means that the weight has to travel further past the center of gravity before it can be displaced, and the effort to make the weight travel past the centre of gravity is a lot harder to make happen.

    Thanks pro70z28 Your platforms are awesome, I especially loved that you showed them actually in use, rather than just standing not in use.


    Problems with some people is that they just get set in their ways, It is easier for them to sit behind their keyboard, concerned by liability and the threat of being sued, rather than actually being helpful because all they are interested in is the negatives.

    I bet nobody ever told the wright brothers that their creations may lead them to being sued or worse, killing someone

    I also bet on the other end of the scale, would NASA, BOEING etc, have never ever had any incidents in their development???

    Hmmm some fastfood for thought there guys.....

    [QUOTE=Broccoli1;271643]The main problem is that ya keep using that MM thang and what is a TYRE?


    From reading other posts on here I think that MM thang stands for Miller Matic, don't it? Heck I gots me a Miller Matic 140 hope to one day upgrade to a MM211. And TYRE probably refers to like TYRE BANKS the fashion model, maybe

    That is what INS. is for...

    ...but I don't see him getting that.

I was pointing out that everyone gets sued when someone is severely injured or dies...If you don't understand what I mean then best of luck to you and I hope you make a million dollars on your design. Problem is you will need 10 mil when the first person is hurt using your design...peace.
    I understand your caution but everything is a risk, sure some things more than
    others but if one wants to design something and sell it I just don't understand all of the fear over being sued. Of course it happens but that is just part of business
    and being an Entrepreneur.
