ATV trailer. tandem/walking axles

[feen]

After a year or so of research, I've finally started my atv trailer build.

Tandem walking axles, possibly multi-body, tipping trailer. Five feet long and four feet wide, and I've opted for a smaller tyre/wheel in four 18x8.50x8 with lawn type tread to hopefully save my lawn.

I'll try and keep this up to date but apologies if I slip.......

Oh and it's going behind a Sportsman 500

So far just the tandem bars

Cheers

Sleeves for outer spindles fitted and center axle beefed up with spindles fitted. Just need to buff and fit outer hubs/spindles and the sub-frame will be complete.

A twin axle trailer is def not grass friendly. I use one quite a bit that has both axles set close together & big floatation tyres. You have to make large slow turns or it rips the grass out especially when reversing. In the big shed on a flat concrete floor you cant move it by hand unless its in a straight line even when empty.

I've got the sub-frame finished and I'm ready to start on the chassis and body after a bit of head scratching.

I can now see that it is going to be a bit awkward trying to turn it by hand but I'm really pleased with how it has progressed and it is exactly what I was trying to achieve.

I'm also now adding a manual tipping ram and I've made up a safety hitch.

Looking very well designed & thought out. Please keep us posted with progress

Looks brilliant so far, nice job.

I used to shunt artic trailers in a factory yard and when you are reversing and turning tightly the inside wheels try to rotate in the wrong direction and leave rubber on the concrete at the slowest speeds, I can imagine what they would do to grass.

I hate to disappoint you but I had a test run today with just the axles and a-frame and it was faultless. I purposely made a lot of tight turns on the lawn and the trailer tyres left no damage at all, which I think is more down to the tread pattern, The quad on the other hand..............

I knocked up the a-frame this morning and clamped it to the axle for a test run. I'm not attaching the two permanently until the body is complete so I can get an idea of nose weight. I was very impressed with the way the tandem set-up handled the bumps at speed. Whilst the wheels are jumping around the a-frame remains steady.

I started on the body tonight but I've an oak fire surround to make tomorrow so it will be a few days until I get back to it.

if thats your garden, i would,nt be to worried about it cutting up the grass!!

 

[feen]

Thanks, it's the bottom of the garden where all the s***e stays, 90m from the house.

Although the grass does need a trim.

[brokenbiker]

if your garden is 90m long, i can see why you need a trailer and a quad lol

 

[feen]

The house is only five years old and is an on-going project. I've led tons of soil from the digger with the quad and a self tipper I made. When you've got the space it's a handy tool.

i'd love a garden that big, or should i say, my labrador would love a garden that big lol

i just want a shed lol

 

[Justme]

Ah yes those tyres are like slicks compared to the ones on the trailer I use.

The fire surround got thrown into the corner this morning and the welder came back out. I got the main tub frame finished and hinges made, just need to line them all up together.

I was a bit dissapointed with the weight, it's up to 125kg with a wee bit more to add. I had tried from the begining not to over engineer it but I decided to add a tipping ram so beefed up a couple of sections. At least I'm confident it's not going bend easily.

Hinges mocked up tonight.

I now regret using angle for the bed rails, they will need a lot of stiffening where the hinges are mounted (you live and learn).

So it now tips, it will achieve 55 degrees with 200mm clearance below the tail when fully raised.

Got the ram mounted up this morning and working.

The chassis is clamped to the axle for now to let me decide on nose weight and departure angles etc. The nose weight is probably going to be around the 14kg mark which I don't think is too bad.

Since bringing the hinge pivot in from the rear to aid the ram on the way up, unfortunately the tub isn't heavy enough to close the ram on the way down, or atleast not to begin with. I can live with it though.

I got a fright when I was charged £28 to get the hose made up, it's all of 14 inches long and it was my own hose!!!!

Should get the axle welded on today then out for field trials before welding it all up.

What sheeting are you going to use for the tub ???
That might help with the tub dropping when its empty.

 

[feen]

I'm using just one sheet of phenolic ply at 12mm thick to do the whole tub. I'm forgetting there will be extension sides fitted so there's a bit more weight in those.
