Can anyone please tell me the basic specs etc of how to make and operate an articulation ramp?

Thanks Heaps

speak to this guy he makes custom ones.

I found a plan once I will see if I can find it for you.

Basics:
But metal, stick together with weld, drive on it.

Generally they operate at either 20 or 30 degrees and it is as easy as wooders says. Buy a few lengths of shs, cut it all up with the grinder, weld it all back together in the shape of a ramp.

look around the side of the road.... thats where i got mine

20 deg ramps are easyer to drive up if its for your daily driver without much gearing.

If its to pose and brag about your ramp score i think its either 22 or 30 deg. If u want it to make sure things clear when flexing, than any angle will do.

I remember the video of the Hummer on the articulation ramp and his mates pushed it over... was teh funnnay

Here's one we built for our club





dident take much to knock up

Is there a formula to the scoring on the ramp?
eg distance up ramp divided by wheelbase or something similar?
otherwise it is a bit pointless ------ anyone can drive up a ramp and say look at me !!!

yes there is do a search on google and you'll find the answer or search here

That troopy looks hot Is that suspension stock?

Or just buy one of these for use and drive over it.

the basic formula is distance/wheelbase*1000

then there is a pro formula which i dont have, which corrects for different ramp degrees, etc.

Anyone know of this formula?

I want that troopy.

RTI = (h/b) * (1000/Sin(A))

where:
h = height of the bottom of the tyre off the ground
b = wheelbase
A = angle of the ramp

It's essentially the same formula as UDM described but the distance along the ramp is expressed as h/Sin(A). This means the formula will work without even using an acutal ramp, or a ramp of any angle.

Standard ramp angles are 20*, 23* (NOT 22*), and 30*.
My opinion.
20* for IFS vehicles,
23* for peoplewho daily drive there Solid Axle vehicle,
30* for offroad only rigs. (and more extreme daily drivers)

I'll disagree with V840 and say that 23* and 30* are the populor two, and 20* is less populor.

Is that made from Silo section??
