I'm looking to build some portable jumps kind of like a skateboard launch ramp but with landings obviously. With the landings in particular, does anyone know any bracing techniques to handle a full size adult pounding on them?

I've built many many skateboard ramps but I'm worried about the impact of two acute tire patch sized forces on just the standard template sides with 2x4s between them. I was thinking of double crossing the braces along the centerline of the "ideal" landing strip in the center of the landings but am not sure of hou to go about it.

Has anyone ever dealt with this?

Thanks

box jump landings are usually just your standard 2 x 4's with plywood over them. space the 2x4's every foot and put 1/2 ply and it should hold up just fine. it's gonna be heavy though.

Yup... "portable" is not exactly the term I would use

after you make it wide enough and long enough to land on (which will be quite large unless you never plan on tricking off it and only jumping totally straight) it will not be portable (unless you call 4-5 peeps helping move it portable)
every attempt at building a landing tranny that i have seen turns out to be so darn big, the only place to play with it in in the front yard.

there are a million and one natural trannies waiting to be used as a landing as we speak, all you need to do is simply go outside to see them.....

Dude that is sweet! Looks like you need to move the ramp back though

Very cool - he could also use a helmet too.

But props for creating your own natural transition to use your jump with!

hehehe...... this was the first time my friend (the dude taking the pic) had come out to play on it and he was concerned about clipping the wall. so i had to test jump it to show him.....

it was the only pic that showed the ramp and the landing which is why it was picked. (not to show off my skillz )

Weight isn't an issue because they will be assembled and disasembled at the site. The sole reason I'm building them is to place jumps somewhere that doesn't lend itself to anything but complete flatness. I've got cargo space, weight and size aren't an issue. I was just looking for any bracing designs that someone like that Dangerous Dan circus brigade might be using for the landings off their bigger ladder drops. If those guys are getting away with straight drops onto standard box designs then that would be fine. I'm just fishing for ideas but it must be a built landing.

So true..........

I think I'm just going to build one and see how it holds up. They won't be seeing the heavy abuse for another 6 months. Thanks.
