DIY Powered Trailer Mover - UPDATE 

Good luck! Make the mover as heavy and low as is feasible

Then I can take it out for joyrides too! Great ideas!

Agree! It needs a second connection point to avoid the rotation. I was able to use some straps to prevent 1 direction, but it needs to go both ways.

Two motors would certainly be an upgrade!

Traction was my main issue! This idea is killer!

@@barefootgaragejax9252 I had problems with traction on a electric wheelchair..... so I did what I said above.... and no more traction issues at all.... if you can get the right size tire that will slip over the drive wheel and the small wheel without cutting it it works perfectly.... but even if you have to cut the tire use a piano hinge.. I used a linear actuator to raise and lower the swing arm... I also put a shock on the swing arm wheel since it was on a wheel chair to make the ride super smooth.... I am helping a friend build a trailer dolly and sent him your video... I told him to use a winch and so..... then I said I bet people have done this before and looked on you tube where I found your video.... I told him to use a bottle jack and weld the ball on it... that way if the ground is uneven you can adjust the height on the go! I used a bike tire since the tires on the wheel chair were 1 to 2".....but you may need a atv / golf cart tire due to the width.. but it is still the same concept. Aires came up with a snowblower that uses a similar idea.... called quick trac or something along that.... but it will give you an idea of what I mean.... I just looked it up.... it is called... Rapid trak... check it out! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E7pjKGSFFXs.html ...... BTW... the higher you can raise the pivot the easier it is to freewheel... you can see the contact surface of the drive tire... the smaller that contact the easier it is to freewheel.... the aires only lifts it a inch or so and leaves to much contact area but still works... if it raised 4 to 6" it is almost the same contact area you have now!

If it make a version 3.0 it will be dual motor

Good idea! I’m sure it depends on the surface. Less psi on grass certainly would make more drag. I think the mover weight needs to increase ideally!

Sounds awesome- please share!

Nice!

Great idea!

I believe my trailer weighs 1000-1200 pounds and the tongue weight is at least 200 pounds. I can lift it, but just for short bursts on pavement. It works for my needs, as it’s not far to go and traction over grass is more important than speed. If you step up the tire size, you may want to change your sprocket size or run two reductions to keep the speed low / torque high. I’m totally happy with the winch, plenty of power and very reliable. I think if I build V2, I may try to use a go kart axle and hubs, as that was the trickiest part to make. Good luck!

Thanks!

Great idea!

I’d love a lipo battery! For this application, the weight of the lead acid is actually an advantage :)

There’s one in the market that uses the 60v dewalt concrete mixer, and it’s sweet! You need a ton of gear reduction for that, which is a bit out of my depth!

Dual wheels would be a huge help, but you want to keep it as low as you can reasonably. I actually too 2-3” out of the height, because it tried to run “under” the trailer instead of drag it.

@@barefootgaragejax9252 in the process of making one myself using the knowledge I have seen and used them to move augers

That’s correct. Push down when moving forward and lift when reversing. Sometimes you have to lift it for the caster wheel to swivel around.

Bummer!

Sorry! RU-vid must let them expire

Sorry! They must expire after a certain time

16T drive and 32T on axle. So a 2:1 reduction. It could use a bit more

30T on axle
