Why don't trailers have tongue casters?

[Egon]

Yup, that surely do look like a wagon!

They don't have a castor there because the proper way to tow for your aplication is to put the weight over the axels.

Interesting caster site there. I wonder, I See the safety chains go to the dolly, Id think the Dolley would also have chains to the truck frame.I assume its all 'approved' etc but I would sure feel safer with more chains to the frame.The concept looks interesting .

any of those products are just a band-aid for an undersized/underequipped tow vehicle. you can buy older 3/4 and 1 ton trucks cheap, and pull your tractor around saftely without issue.

the large trucks using the converter (like the model pictured) are used for several purposes. the dolly-called a "jeep"- is to spread the weight of the load over more axles and tires as to not over load them. it also takes some load off the truck, so the truck is not carrying so much of the load, just pulling it. some of these loads would be wayyyyyy too much for the trucks drive axles to take that weight alone. the jeeps also give it an extra pivot when steering, making going around corners easier. what these guys do should usually not be carried over into the "consumer" trailer area.

Would it become a tricycle wagon ?
I think the tongue would need to be jointed, or the tongue caster would leave the ground and come back down from time to time.

At first glance I would guess UNSTABLE, but done right I suppose it could work.
"Done right" requires some engineering (or at least some "design") and that doesn't seem to happen in the small/light utility trailer building world.

So last week on my customs brokers' dock, he has this thing that looked a little like a converter dolly for a big truck. It had small tires, like a lawn trailer type tire that took 90 psi. They were about 2' apart. It had a bearing on top made from an axle hub. Safety chains, but no visible hook, on the front and a channel on the back that looked like it was meant to adjust the height of a hitch. Came from an RV place but the packing slip gave no information because it was scrawled in an illegible hand.

What was it?

A boondoggle meant to separate a customer from their money? Sounds interesting whatever it was.

I sent a cell pic, that I regretfully deleted, to a pal in MI who has his "Testosterone License" as he calls it, to haul a set of doubles with a pickup truck and did not get a reply. Leave it to a GM engineer to not have an answer.

Not necessarily. If you look at the trailer that I posted a picture of, you can see that'd put much tongue weight on any truck. If you have a truck truck that can haul even just 8,000 pounds with a 1,000 pound tongue weight limit, even a little Kubota BX on that trailer would exceed the tongue weight, but still be well within the towing capacity of the truck.

Very cool front attachment in your picture/I wouldn't mind painting th house sitting in that lol
