ATV Trailer Build

It doesn't really show it in the animation but the walking beam would have more movement than the leaf spring, but for the on road leaf springs would be good and off road walking beam so it's really application specific.

I've used a 1-7/8" ball hitch several times and it works very well. Good articulation, fast and easy connection, doesn't come off when you drive over objects that catch.

Honestly, I'd ditch the walking beam suspension. Too fancy. I have a single axle on my trailers and I can still load them more than what my atv can move.

your right there you can put a lot of weight on the single axle, I have a single axle trailer that I can load to where I have trouble pulling it with my atv. and that's with some good down pressure on the tongue...the thinking behind the walking beam (ive never had the opportunity to use one) is that it will hop over mounds/logs/curbs/roots much easier I know with my single axle if im trying to back up and have a small obstacle behind one tire it wants to twist sideways sometimes rather then go over it. that being said the idea would be to make a walking beam but not make it any heavier then a single axle...that's where the work would come in..

I've got a friend with an ATV trailer that has a walking beam axle (don't remember the manufacturer..) For rough off road use it seems to work pretty well. But he says it does have one problem.... sometimes when going through holes that are either bigger than the tires or has a step to get out that is over half the tire height, the front tire gets hung and forces the axle down picking up the rear tire.... it will also hang up some times on tree stumps. His trailer does have a LOT of travel before the axle limits out....

Just something to think about...

Good luck

I was planning on using a 50mm ball hitch (I think that is slightly bigger than 1 7/8in). I think walking beam suspension is decided. It is going to be used on a pretty rough road, in performance I don't think a single axle would compare. I am building it with a walking beam because of the suspension advantages not the weight carrying advantages.

well keep us posted with pics and details during the build and try to keep the weight down as much as you can... I don't know about Australia but here in north America. 1 7/8 and 2"are the standard ball sizes I prefer 2" on everything I own as I don't wanna have to have 10 different trailer hitches!!!

One of my earlier projects:

Can't find the build pics of it! I built it to haul the 140 in parades, so it is designed for hard surface. Problem was the 6" wheelbarrow tires would pry off the rims when turning, so I eventually went back to single axle. I needed to be able to take the beam off the center axle for transport, so they were on 1" pins with lynch pin keepers. beams were 3" channel iron with a 1" pipe welded in the center for the pivot. ~~ Lowell

I think what your describing is why they call them "walking beams". If the front wheel hangs up, then the rear will pivot over and forward to continue over the obstacle. If there is something limiting that action, such as a fender, then...yeah, its a problem. The true walking beams trailers need full rotation of the 2 wheels at the center pivot

A fellow in Alaska builds these with the walking beam. As it can be very rough going it works well. Just has the one axle across with beams on either side for the floatation type tires. If it gets in a hole it will just rotate over and keep going. Is a slick set up and with the tandems it is easier to pull in soft ground.
