Sorry folks.

Talking out of turn again . . . never even thought. I just can't get my head around detachable goosenecks. As I have mentioned I have never seen one or envisioned a situation where one would be useful.

Cheers.

If you would have ever slid an excavator off the side trying to load/unload in the dead of winter (icy, snowy tracks and frosty iron) you would never have any desire to load up the azz again. Been there, done that with a 25 ton excavator and laid it right over on the cab side. I'll keep my detach. :)

Most single axle dollies are setup to be close to neutral tongue weight. I'd don't think a run of mill SA dolly is gonna stand up to 30k of kingpin weight. Another issue that may apply, your state might prohibit converter dollies directly attached to a truck. In Kansas any dog/wagon/full trailers pulled directly by the truck have a turntable requiring a floating hitch, so no tongue weight. I don't know if we're the only state with this silliness, but i can hope. I see a lot of harvesters pulling grain trailers behind service/straight trucks for moving. Either they don't know or don't care i give it 50/50.

This trailer is for sale near here and is the sort of thing I would like to have one day, probably with one less axle though.
It is set up to remain under 19m which is the maximum allowable length for such a combination.
We don't get too many snowy/icy days over here, although I've seen a few utube clips of what can happen.:)

Gotcha there Shimmy1 This detachable gooseneck thing has always intrigued me.

Are they used in other places that have ice and snow . . . tctractors or any of our European posters care to chip in with a comment.

I spoke to a Kiwi heavy haul contractor in Christchurch and he seemed unimpressed with the concept. He reckoned a good long beaver tail and twelve foot hydraulic ramps were all they used.

I see some of the Bifold hydraulic ramps available these days provide less than nine degrees of angle and can deploy with a remote in just a couple of minutes.

I suppose though the ramps would be a bit heavier than the detach mechanism.

Cheers.

Small contractors around here use rear load with ramps. One guy does have a detach but bought another out and all I see him pulling now is the old rear load he had. Most of the jobs I do are a short jobs. Some times I might hit two or three a day.

Granted the detach is easier and safer but a soft farm field or over to the side of a narrow gravel road and a detach becomes a pain. I'm thinking a short stiff neck lowboy with long ramps. My pintle hitch has a six foot tail with almost five foot ramps.

I don't know the laws yet in Missouri and something like this might not fly. There is a guy I've seen about 70 mile from me that has a dolly hooked to his lowboy and pulls it with a steiger fwd tractor. Has it set up for air brakes and pulls a 70 to 80,000 hoe behind him.

Not legal in IL or safe anywhere IMO. Here, "farm wagons" as I'm sure this genius is calling it are limited to 36,000 gross. Also, IL specifically says gooseneck type trailers are not farm implements.


Are there no height restrictions in Australia? Here in the US, we have to be under 13'6 (4.1m). You don't need a very big machine to get real close to that restriction.

It must be weight restrictions, but all you see here in this part of California is mechanical RGNs for the most part.

They require no hydraulic pump and tank to weigh down the tractor, or small engine on the trailer to never start when needed.

Simplicity wins most of the time I would say.

I could be speaking out of turn again but I think here in Queensland 4.6 meters is normal max and over height permits are available on some routes . . . Queenslander or some one still in the trucking game will correct me if I'm wrong.

Cheers.

Scrub, I believe it is 4.3 for heavy vehicles generally, 4.6 for double deck car carriers, livestock trailers and indivisible loads, ie. oversize.
B doubles and road trains with drop decks or floats can go to 4.8 but are restricted to road train routes.
5.0 for indivisible loads with pilot/police escort.

The height can be an issue in my area. We're legal for 13'-6" but that doesn't mean anything for the old overpass that has 12'-8" clearance.:cool:

I was just going to say that, about the only thing around here that is 13'6" and above are the interstate overpasses, most the old county bridges are short, sometimes only 12'.

Here is what a detach aka lowboy looks like Scrub, takes the deck height from 36" +/- down to 18"-20"+/- 16" can make quite a difference depending on the size of the machine and loading conditions. Not my machine or trailer, just a pic off the web :D

And this is how it looks split apart. Pretty sure its much easier also getting a roller on one of these than a deck over with ramps.

Gotcha Queenslander,thanks for the heads up, I was a little unsure and too slack to look it up.

Thanks too for the pictures movindirt . . . the detach system sure allows for decent sized tyres on the trailer.



Cheers.

That would be a mechanical folding neck I would guess. Don't see them around this part of the country, just guessing they would be something used a lot in the oil field industry as it seems most of those trucks have a big winch behind the cab. Being able to winch them back on the truck would eliminate a ground bearing trailer not being able to return to loading height from soft ground.

Folding goose neck trailers where like A holes at one time, everyone had one. Then along came hydraulic and air supencions, bifold ramps which all had lower tare weights so they became a thing of the past. Side loading a folding gooseneck as a sure way to stuff the pins in the gooseneck then they wouldn't fold up or down. One other down side to them was to may drivers were to lazy to throw an old car tyre under the slip plate and when they lifted it up they would bring dirt up over the turntable(fifth wheel) and wore it real quick.

Gotcha Tones. Shows how things are done different in different places, I have never seen one out in the sticks.

I imagine all detachable and folding systems would have issues with constant use on rough and corrugated roads,

Cheers.

Tag trailers are the go to trailers for shifting small equipment ( up to 20 tons or so) here in Oz especially for the small operator doing muiltiable jobs a day. Bartlet ball is the preferred coupling or though some use a pindle hook. A Bartlet ball is much smoother and easier on the trailer drawbar but has less load capacity where as a pindle hook is much better in an off road situation. If you want to go all out Tag trailers can be manufactured with widening deck , self steer axel. One of the best features of a Tag trailer is that it can be towed loaded with an empty truck as opposed to a loaded dog trailer which you should have some weight on the drive axels( more than tare weight) in order to have better control on the road. At the end of the day it's all horses for courses.

Thanks Tones. For those (like me) who are unsure of the terminology . . . i.e. "Bartlet ball".

It seems they come in several sizes . . . on the largest the ball is a tad over six inches in diameter.


Cheers.

I was once told by a reputable excavator that the reason there are so many 20 ton excavators is because there is a limit on the weight of a tag along trailer. Excavator model numbers are about metric tons. Put a 20 ton excavator on a three ton trailer, some of the weight is on the hitch. Somehow the math works, 20 tons on the trailer tires?
