PFB Tri-Axle King Hauler
 

Need something to tug the 850D around. Got the rails cut/drilled/tapped tonight and got it in roller form:

Went with Russ's new airbag suspension. Super nice stuff and makes it super easy to link up multiple axles.

Had the regular roadys so I was excited to see the wide guys come out:

Plan to try it 8x6 first, if needed I'll drop in a TLT up front. Plan to use a Holmes Hobbies puller on either a 3-speed or an HD RC4WD R2 trans. Been using their "Mega Truck" drivelines on the dump with no issues. Pricey but they will hold up a good while. Will eventually mod the body to a pete as well. Still unsure on daycab/sleeper.

Re: PFB Tri-Axle King Hauler
 

Looking good Nate. :cool:

The 850 will certainly be the ultimate for a durability test on Russ's suspension components! :D

Tri drives... wide turning radius, if it turns at all! You americans don't use jeeps?

Re: PFB Tri-Axle King Hauler
 

Great looking truck, so far! I really like Russ's suspension too. The nice thing is you will be able to tune it's capacity, with heavier springs, if you want. We are really lucky to have some great vendors now, right here in our own part of the hemisphere.

Hmm, so let's see. 80 pounds spread over 6 axles (not counting the steering axle) would be a bit over 13.25 pounds per axle. Add the weight of the truck and trailer itself, and it's probably going to go up to 18 or 20 pounds? That's heavy hauling!

Re: PFB Tri-Axle King Hauler
 

Maybe I don't drink enough maple syrup...what's jeeps got to do with it?

Re: PFB Tri-Axle King Hauler
 

Jeeps are for mud boogin :p Joe , A co . down hear moves a 385 cat with a triaxle tractor and a 5 axle trailer .

looks good Nate . you might want to center the 5th wheel over the 2nd rear or make a sliding fith wheel . If your building your own trailer make the neck long .

Re: PFB Tri-Axle King Hauler
 

Nice truck, starting to look like Freddy's black 8X6. I know this is getting the cart before the horse but what are you going to have for a lowboy?

Re: PFB Tri-Axle King Hauler
 

Looking really good, she is going to be a heavy hauler for sure.
I'm waiting on a set of russ's suspension myself, and can't wait to get them.
Keep up the good work.

Re: PFB Tri-Axle King Hauler
 

Noted! 5th isn't mounted yet.

I have Izzys old tandem lowboy I may try to extend it but will probably just build a new one

Re: PFB Tri-Axle King Hauler
 

Looks like you are off to a great start Nate it should look real good pulling around the excavator.

Re: PFB Tri-Axle King Hauler
 

That trailer is real nice but it would look all wrong with that monster on a tandem low boy.

For instance here's what pulls a stripped down Zaxxis: http://www.coesens.com/fotoboek/imag...20x%20642).jpg

Re: PFB Tri-Axle King Hauler
 

Nate , you may be able to just build an extension to the gooseneck that flips down . I've seen a real 1 like that somewhere in my travels :confused:

Re: PFB Tri-Axle King Hauler
 

Hey Steve like this? Flip over neck http://www.xlspecializedtrailer.com/...rn-Canada.aspx Full Jeep picture, http://www.xlspecializedtrailer.com/...lti-Axles.aspx
Later, Neil.

Re: PFB Tri-Axle King Hauler
 

"You picked the 1st one that appeared on google images, didn't ya Stevie?! "

nope I went on trail kings site :p I guess I could take a crapy pic of a set up I drive by every day . they don't use it much

Re: PFB Tri-Axle King Hauler
 

Are you going to send it to Freddy to get the bubble wrap paint job??????????
That way it will match your dump!!!!!

Re: PFB Tri-Axle King Hauler
 

:DThat's looking awesome Nathan..i cant wait to see how this turns out......:D:D:D..I think i see my baby in the backround..:D:D

Re: PFB Tri-Axle King Hauler
 

Ahahaha low blow :D (it's still like that......cause I'm lazy as ****)

Re: PFB Tri-Axle King Hauler
 

wow, that frame is clean :) as far as i know this is the first tri-axle to use my "air ride" the truck should look killer when its done

Re: PFB Tri-Axle King Hauler
 

Hmmmmm,I believe you have a Tri axel.....don't ya:rolleyes:

Re: PFB Tri-Axle King Hauler
 

Here is something to shoot for. This is a "beam" or a "rail" lowboy the deck is just frame rails that are set in narrow, you drive the excavator over the rails straddling them, the whole thing sits lower this way.

Re: PFB Tri-Axle King Hauler
 

Been wondering how those work. Does the deck the excavator sits on raise/lower?

Re: PFB Tri-Axle King Hauler
 

Here's a nifty vid showing a mechanical disconnect neck & a winch line. You can see the extended neck on the lowbed clearly as well.

Re: PFB Tri-Axle King Hauler
 

Should have known to look on his channel. Love his vids. That thing would probably be pretty simple to make too. Much easier to hide a winch than a screwdrive lift.

Let me put on my lab coat here and talk some theory on the physics with the model:
If the weight of the 850D excavator is supported entirely by the trailer/jeep, you would need to add more weight to the truck to efficiently pull the load correct? Or add a weight box to the extended neck?

Re: PFB Tri-Axle King Hauler
 

the idea is to uniformly distribute the weight on all axles including the tractor . placement of the 5th wheel is crucial ( hence the sliding 5th wheel plate ) Here in PA ( last time I moved a permit load ) , we're alowed 20,000# per axle at a given distance appart ( I gotta find my PA DOT book ) . If you look at the position of the 5th wheels on the aspen set up ,it transfers enough weight to the tractor .

Re: PFB Tri-Axle King Hauler
 

Very cool video, Joe.

PFB, the weight of anything you haul is not entirely supported by the trailer. Even with jeeps, some of the weight is still transfered to the tractor's 5th wheel, and that's key. Unless the lead jeep is pulled from a drawbar, like a wagon, the tractor will still have weight on it. Then you would need a weight box on the tractor. You probably would need less weight on the tractor, then one might think. Say something like 15 to 20 pounds of weight on the tractor's 5th wheel would probably be enough to pull 80 pounds gross. Depending how freewheeling the wheels are, and how stiff the tires might be.

Re: PFB Tri-Axle King Hauler
 

A very kool channel indeed Nathan, I've learned a great deal of different techniques to operating equip from his numerous vids. He always has the camera in the right position to see the action, they're always entertaining to watch. :cool:

Re: PFB Tri-Axle King Hauler
 

That's where I went to reference controls for the 850D haha busted!

Re: PFB Tri-Axle King Hauler
 

Europe tends to like to have the load entirely on the trailer / bogey set-up. They also like double axels rather than single axels (two short axels with a total of 4 wheels). I believe this has to do with manuverability - with euro styling they have shorter turn radii and also use steerable axels whereas here were all about length - we got plenty of acerage..... hence the large cars LOL!

Re: PFB Tri-Axle King Hauler
 

Not a very good photo but this is Bill Signs moving an 850 Hitachi, your Deere is basically the same machine.

Re: PFB Tri-Axle King Hauler
 

I say we need to get REEVE2007 in on this discussion as he is our in house expert. No offense meant to any body but lets see what Donny has to say as he has probably moved a couple of these.

Here is one of Precision Heavy Hauling in Arizona moving a Deere 850D.

Re: PFB Tri-Axle King Hauler
 

I think it is a **** of a start to a cool build. The truck looks beefy just like a heavy haul should. I think everybody is on the right track it just depends on what spot in the hemosphere you want your trailer replicated after. Different areas have different requirements for weight and over the years some very smart inventers have designed equipment that is capable of hauling the weight while staying with in the weight requirements. You could use a goldhofer which is like a dolly that is pulled by a truck or multiple trucks or you can build a trailer like one of the photos used above. The 2 being hauled by Bills and Precision Heavy haul are the style we use most. It would really be something to see someone accomplish one of these. If you are interested I have thousands of photos I can supply. On these trailer types the main deck carries the load. Each end is connected to a neck which is supported by the jeep in the front and a dolly in the rear. The point where the neck connects to the dolly is centered between the two groups of axles on the dolly. On the other end the front neck is connected to the jeep. This point is centered between the axles on the truck and the jeep acording to the weight requirements. This being said the truck will have weight on it to enable it to have traction enough to pull the load. So as long as you build the load bearing points correctly on the trailer the weight will be disributed evenly.

Re: PFB Tri-Axle King Hauler
 

Def. a build worth following.... what is the length of your frame rails?:eek:

Re: PFB Tri-Axle King Hauler
 

+/- 26"


Haven't done much work on her lately, but I did go ahead and hack off the sleeper. Not sure if it'll stay this way depending on electronics layout but the trans/motor fits nice even with the interior in it. The front bumper will be milled smaller for more clearance.

RC4WD R2HD Trans with Holmes Hobbies 7t Cobalt Puller should do this rig proud. I'll be able to put a powered axle in front should I decide it needs it.

If it stays a daycab, the headache will need to be cut down a bit.

Re: PFB Tri-Axle King Hauler
 

One thing to consider, on grade's or off road site's, I have heard of 980's & 988's pushing the trailer, to help the truck out and not squirt the driveline out.
This is worst case senerio,
but at the show's, it's nice to have friend's help out with that "BMF" load!
That's big monster frustrator for the clean version!
The old Gibbon's & Reed Pit in Kaysville, Utah, had close to 20% grade going up into the pit.
Cheer's, Neil.

Re: PFB Tri-Axle King Hauler
 

20% that is steep. the best i ever did was 17% in (you may not believe this ) in iowa!!!

Re: PFB Tri-Axle King Hauler
 

Give or take, Just not truck friendly!
Cheer's, Neil.

Re: PFB Tri-Axle King Hauler
 

A Holmes Hobbies 7t Cobalt Puller, are u wanting to shred some tamiya axle gears and twist a drive-shaft!
