PFB Tri-Axle King Hauler

[pigeonfarmboy]

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.

[Lil Giants]

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?

[Espeefan]

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!

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

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 .

(edit) here you go http://www.trailking.com/trailers/?trailer_id=45

[Claus]

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?

[glorydays24]

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.

Big John

[Tamiya Cowboy]

Looks good cant wait to see more but steve is right you should have the plate set over or ahead of the center axle..

[pigeonfarmboy]

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

[fhhhstix]

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

Travis

[Tamiya Cowboy]

That s right I forgot you got that from Chris.. Great trailer it will all look great together..

[pigeonfarmboy]

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/images/Hitachi%20870%20028%20(855%20x%20642).jpg

[ihbuilder]

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:

[doodlebug]

Hey Steve like this? Flip over neck http://www.xlspecializedtrailer.com/construction-trailers/XL-Hydraulic-Detachable-Gooseneck-Eastern-Canada.aspx Full Jeep picture, http://www.xlspecializedtrailer.com/construction-trailers/XL-Hydraulic-Multi-Axles.aspx

"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

[spudd]

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

[Stylin n profilin]

: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

[pigeonfarmboy]

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

[russisloud]

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

[rc10johnny]

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

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

[Claus]

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.
http://www.things2move.net/images/bimg5.jpg

[pigeonfarmboy]

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

[pigeonfarmboy]

Ooooooh http://www.youtube.com/watch?feature=endscreen&NR=1&v=T7Dd7pFqew4

[Lil Giants]

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.

http://www.youtube.com/watch?v=G8EAGjh_D4Q

[pigeonfarmboy]

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?

[ihbuilder]

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 .

[Espeefan]

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.

[Lil Giants]

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:

[pigeonfarmboy]

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

[Izzy]

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!

[Claus]

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

[fhhhstix]

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.

Travis

[Claus]

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

http://www.precisionheavyhaul.com/equipment/3842-JOHN-DEERE-850D.jpg

[REEVE2007]

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.

[sgt hopkins]

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

[pigeonfarmboy]

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

+/- 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.

http://farm8.staticflickr.com/7027/6643122811_3509fb8feb_b.jpg

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.

http://farm8.staticflickr.com/7018/6643122433_0e9eeb0fbb_b.jpg

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

[doodlebug]

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.

[fuzzy]

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

[doodlebug]

Cheer's, Neil.

[rcguyfarms]

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

[Lil Giants]

What's the spec's on that motor?

[pigeonfarmboy]

I've put a fair amount of stress on these ring and pinions before. I know they'll fail eventually though.

Specs on pullers:
You can't find a more powerful brushed motor in this class. You get insane wheelspeed, more torque than any 540 motor, and the finest slow speed control. All in one motor. 7 slot armature allows for better throttle resolution with a high motor speed.

Recommended lipo battery-

6t- 2s only. 40a continuous
7t- 2 to 3s (3s may result in overheating). 45a continous 11.1v use, 35a continuous 7.4v use
10t- 2 to 3s. 40 amps continuous 11.1v use, 30 amps continuous for 7.4v.
14t- 3 to 6s. 35a continuous 22.2v use, 25a continuous 3s use

Slightly longer than a standard 540 motor. Uses standard 1/8" pinions, and 25mm motor mount spacing- bolts up like a normal 540 motor. **Some stock uses 4-40 mounting screws that are included**

Super Strong cobalt magnets
7 slot armature
6.9 ounces, 200g
2.5" long, 1.35" diameter
5-10 volts
160*F max

6t- TBD
7t - 2800 rpm/volt
10t- 1800 rpm/volt
14t- TBD

[Espeefan]

You should just go ahead and give this truck a powered front axle. I think you'll like having it, and it would raise the front bumper up a touch. You might not even need to mill it. If it's worth building, it's worth over building!

[hvy 1ton]

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.

The winch isn't a required bit. The guys up north use winches to pull the trailer up the ramps to save the driveline in less than ideal conditions.

[kcjeepn]

Very nice rig!!!!!

[crawler07]

great looking rig man.

[CustomClod]

I like it! Keep the sleeper off. Looks better!
Scott
Just my opinion

[CHEVYHD496]

this truck is awesome. im a big fan of tri-axles! just wondering, but i was wanting to get new frame rails for my KH and wanted to know what height yall are using? im gona buy aluminum C-channel. thanks

[pigeonfarmboy]

Just buy some from GardenTrucking.com

[pigeonfarmboy]

Got some work done on the rig tonight.

Here's the mount I came up with for the R2HD trans:
http://farm8.staticflickr.com/7066/6981353503_efc661dfb9_b.jpg

It's only mounted to one side so I thought I was going to have to brace it to the other side frame but it feels pretty solid.

http://farm8.staticflickr.com/7201/6835227268_4ec5be13c8_b.jpg

[Tamiya Cowboy]

YEEEEAAAH BUDDY! That motor will do the trick I have one in my tri axle and she pulls like a champ.. I am glad I got a few before they stopped making them.

[Espeefan]

Thats a pretty nice trans mount! Looks beefy. I'd build another for the otherside, if it was mine, but sometimes when you are making parts like this, by hand, you're lucky if the holes come out where you want them, and they line up the first time! It becomes a question of you deciding if you really feel like making a copy of the same parts!

[pigeonfarmboy]

Theres no mounting holes on that side of the trans. Would have to tie a bracket in from the top. Problem with that is the top of the trans already hits the interior floor. Would like to keep that in tact if possible.

[Izzy]

With that frame support just behind the trans I think you will be OK - at least untill most everything else is mounted up. Why not poke some holes in that other side? you would have to take it apart to clean up the shavings and such though...

[pigeonfarmboy]

Why is Izzy always wanting to poke holes in things? Weirdo... ;)

[Kaf343]

Truck looks great, liking the suspension.

[pigeonfarmboy]

For those that don't venture into the construction section:
http://farm9.staticflickr.com/8421/7617609016_2349036a3a_z.jpg

[pigeonfarmboy]

After several torch welding failures to notch the rear frame, I decided to machine an end cap instead. I think it turned out good and will look nice under paint. I can even mill out the delrin block and make room to hide electronics in there.

[fhhhstix]

Good job Nate it looks really nice.

Travis

[woodhog]

Looks really good. I have been using a delrin mount in the front of two of my trucks to mount the front bumper to and it works good and machines good

[dabears]

nice and clean looking i like it! Thats a great idea!

[Kaf343]

Nice job, looking good. Can't wait to see more.

[SuperDutyScaler]

hey pig do you have any more extra wide frnt tires mounted? I was gonna orer a few sets but im not sure if they will look good on the stock width wheels?

[pigeonfarmboy]

None of the super singles look good in my opinion. Probably the tamiya ones are the most accurate to what we have in the states. None of them have the right sidewall bulge to my eye.

[sandfarmer]

Love the Budd wheels and hubs, looks so scale it's not even funny!

[tc1cat]

I really hate to burst your bubble but paint is not going to stick to the delrin block. It might look good at first but the first time you bump into something:mad::mad:

[Claus]

Make a new rear deck plate and extend it wrapping the diamond plate around the delrin block.

[pigeonfarmboy]

Make a new rear deck plate and extend it wrapping the diamond plate around the delrin block.

Good thinking! I need to cover my drill mistake on the rear anyways.

[Izzy]

FYI - some aluminum doesn't weld worth a hoot. But my local guy does mostly tig welding.

Wrap around deck plate will look good.

[Izzy]

Nate - any updates?

[pigeonfarmboy]

Nope. Been racing 1:12 rc and taking lots of photos instead of building.

[pigeonfarmboy]

Picked up this headache rack on ebay a while back. I liked the fact it lifts out of the way so I can access the battery in the sleeper.

http://farm4.staticflickr.com/3823/9508318718_7da6d727df_b.jpg

Still hadn't fixed the rear crossmember cover up so it was time to change that:
From this:

To this:
http://farm4.staticflickr.com/3795/9512130972_ff8ee0b5ef_b.jpg

You can see I also had to make a 2nd extended version of the electronics receptacle plate so the deans harness wouldn't hit the bottom of the headache rack.

Mounted up the gooseneck. Just need to run extensions to the receiver for aux control on the neck lock and my Izzy Bottom Dump train. Going to try to get some fenders and mounts fabbed up too.
http://farm3.staticflickr.com/2841/9509347965_77d7b6be01_b.jpg
Probably will do a body overhaul after Indy. Thinking Kenworth C500B to satisfy the beef factor I'm after :)

[speedy8305]

hey cool truck but isnt the 5th wheel a lil too far forward shouldnt it be centered between the rear 2 tandems

[pigeonfarmboy]

Most of the trucks I researched had it set right where I do. I haven't checked the spacing for my bottom dump trailers but those might need the 5th wheel moved back. I will eventually have an adjustable either physical or screw drive setup to move it.

[speedy8305]

sounds cool keep up the good work

[Trucker_Jo]

The diamondplate is very nice. I love the idea of the C500, i'm hooked on this thread. I have to say that the headrack on the 5th wheel servo plate looks off, are you going to put in a new 5th wheel mount, like a scale sliding mount that you can move pins for different locking positions? Anyways it looks good, hurry up and make that cab :D
Jarrett

[pigeonfarmboy]

I'd like to make a mechanical sliding 5th wheel plate. I'm planning on getting a lot of time on this rig at Indy and then plan what needs changing. I think the C500 would be a good first project for a 3D printer. I plan to buy the next generation from maker bot. Maybe I'll just design and get shape ways to print one out. Hmmmm.

[Trucker_Jo]

That would be very cool to see some more 3D printing action. :bounce: Good luck cant wait to see the finished product.

[pigeonfarmboy]

Looky what I uncovered today. Travis if this isn't a good ad for your grills I don't know what is.

Wow, that's a depressing sight! Hope you get thing's fixed soon.....Neil.

[Lil Giants]

Good to see you have a sense of humor (& still your sanity) in dealing with the after math... has the cause been determined yet Nate? Have you made a plan yet for the rebuild?

[ihbuilder]

looks like some of the wheels made it :) man that whole thing just suxs :(

[Tamiya Cowboy]

That right there is my biggest fear.. Fire cause normal household items are easy to replace but the semis I dont trust the insurance company on that.. Nate that truly sucks..

[speedy8305]

hey Im sorry to see that I had an incident like that about 7yrs ago I lost about 20,000 in un replaceable damages i hope you and your family are safe though

I haven't been keeping up with the board too much lately, kind of more of a winter thing for me, what the **** happened??? Your truck was looking so good.

[RCP57]

This truly sucks! It gave me enough of a slap though to make a call to our insurance company right after this happened. I still have to get appraisals done for my stuff to establish value though, which is difficult with scratch builds. When I do the models will be covered in the event of a fire or other natural disaster...so long as it's not a flood or an earthquake or a....blah blah excuse.

I hope you can overcome everything and get back to a normal life soon!

[Claus]

Gone but not forgotten, are you going to build another?

[Claus]

Still waiting for a reincarnation!

[Claus]

Love watching the truck squat as the excavator loads up.
