Hey Pairoa,

as always big respect for your work. Nice efforts.
To be honest...I also had a little smile on my face, when I saw the pictures of Isolation on the amazing painted Cabin. All the beauty....destroyed :) ;)

Keep up the good work!

Cheers

Dear waYne:

Nothing has been destroyed... just think of it as if all that beauty has been carefully hidden instead... and behind any cover, any bolt, any layer of paint, lies something quiet wonderful, witness and depository of many hours of careful work.

Regards and thanks.

Hey Pairoa,

I guess you are right. This and only this is the right way to see the truth. Was a little bit short-thinking and, to be honest, a little bit ironic ;)

Keep up your way!

Cheers

More great work Pairoa, great job on the sound insulation, your ears will appreciate it a lot and each bit you add makes just the little bit of difference. It is nice to see you building in a good sound system, it is well worth it on the long boring trips the stretch between all the beautiful places.

Hi Pairoa,

I check this thread every day to see if you posted something new.

Since it's been a while since your last update I was wondering and hoping that everything is fine and your project is progressing as planned.

Wish you all the best!

Best regards

Hey Pairoa,

hope everything is fine and you are not stuck in the pre-christmas-hurry.

Would be awesome to hear something from you! Yes I am curious ;-)

Hi guys:

Well... in fact... I am stuck since a few weeks. The air conditioning issue has been a real nightmare. I depend on others and these others have been having quiet a bad time, dragging me and the project down with them.

If I do not install the condenser under the dash I cannot instal the gauges and the controls of the components of the suspension, the lights, the CTIS, the stereo and so on. If I cannot complete the dash I cannot mount the cabin on the frame. If so, I cannot complete the circuits for the brakes and the pressurized air systems and, like this, forever.

I have done minor things and received a lot of new components from all over the eBay world. On the other hand, I have done a pretty nice trip around and took a lot of nice pictures and have some news about the bikes, one of my other passions. I can make a whole new story of this but I am not sure if this is the right place. Yes...I am aware that I have already done it... more than once, but I want to hear opinions about the idea before doing it again.

Thanks for your concern and the good vibes.


Pairoa

For a number of reasons:

- I have no place to build and assemble the Cabin here in San Felipe.

- My old man is busy flying around so he cannot commit with the project for now and work on the cabin at his place.

- I need to assemble the tuck first and then make all the twisting tests to ascertain by the milimeter the precise torsion movements the frame does so I can design and build the frame of the Cabin adjusted to these measurements. There is no chance of building a four/five point pivoting system based only in theory, You have to be sure and see where it moves and where it stands.

- I have been using my time out of the Merkabah fever to service the bikes and the Montero. They needed some attention since quiet long.

- The building of the house, the real one, is about to begin. I cannot fight at so many fronts.

And surely I am leaving something forgotten in the pockets.

Cheers.

Hola Pairoa!

The twisting test will be the smallest problem of all. Just put some weight on the back of the truck and off you go ...
http://www.allrad-lkw-gemeinschaft.de/phpBB3/viewtopic.php?p=128885#p128885
(No, it is not my own truck)

But I know your situation with all the other problems, tasks and projects to do all in the same, but limited time all too well. There is no other way than to do the best you can and hope for a better future.

Keep up and greetings to Carmen and you!

Pirx

@Pirx:

I knew that truck and the test they have done. I bet you wish it was your truck, he, he...

The thing is that I want to make the tests and measurements BEFORE building the frame/floor of the Box. We will see what we come up with when the time comes.

Thanks a lot and greetings from Carmen to you, Bärbel and Heiner.

....did you ever consider to make the whole thing a "Schoolbus"??

OR in other words "One Stiff Box!"

I know your chassis is supposed to take some of the suspension work by twisting.

However I think you could also let the suspension do ALL the work a take the chassis out of the equation.

If you build a space-frame and bolt it directly and solidly to the chassis - at various locations (for your ride I suggest 8....) - you would not have to worry about the interface of the box with the truck...
After all your dump-truck chassis is built for direct load platform mounting (albeit with hardwood spacers recommended)

In your case - for a space-frame to work properly you would have to tie in the very front of the truck too - which could be done via extension over the driver cab and then down onto the chassis-rails....

The space-frame would be easiest built based on triangulation...

I am way too rusty to calculate the material sizes, but I am sure here in the group someone would be up to the task (or worse case contact the Mechanical Engineering Department in a University in Santiago - students are always interested to get their hands "dirty" on real world projects!!)

Incorporate the chassis as part of the Space-frame.....

You would get one hell of a stiff unit - which would take up a good part of the suspension work the chassis doesn't do anymore.

Obviously you would have to look again at your suspension and make sure the moving parts are up to the task to take care of 100% of the work now!
Considering that you probably never get even close to use up all the design weight capacity of your truck, I think it would be something to think about!

Weight-wise it should change about nothing - with the benefit of a way stronger unit!

I know - everyone is concerned about twisting damage on wrongly or badly mounted boxes!! BUT - most of that comes from "not knowing what they do" - and mostly those boxes are not designed stiff enough and/or not mounted solid enough to the chassis.

If you take that approach however (properly designed - calculated!!) you end up with a US-SChoolbus box!! Basically a Squarish box, mounted fix on a Medium Duty Truck Chassis - for a bus, WAY overkill, but tUS regulations require a quite high roll-over stiffness specifically for Schoolbuses! With a high-strength steel profiles you should be able to copy that system quite easily....

Remember - you will have a Rolling HOME, not a Unimog-River-Crawler or Dakar Racer [no matter what your Truck ACTUALLY WOULD be capable off - you are NEVER going to risk to find out! I'd say more likely than not - it will be a "Bad Road Warrior" - not a "OFF ROAD Truck" - ....I don't count Dessert and open madows as off-road]

....just an idea - while you can't do anything else! ;)

Cheers,

thjakits

thjakits:

Thanks for your brainwork. Unfortunately, incorporating the cabin, the Box and the frame in just one stiff unit is way more easy to say than to do, and the results are absolutely not clear concerning the performance and durability of the truck with such an arrange.

One thing is clear, though: I need the truck to be ready to do whatever it could be urged to do. I like offroading, pretty much, and the primary goal of having selected and purchased a 6x6 truck is precisely to use all of its potential to get wherever I want and whenever I want, dunes and rocks and asteroids included.

Twisting of the frame is good for the frame, it is healthy for the frame and it is what it is primarily designed for, as you well say. I cannot rely exclusively on the suspension and add steel to build a monocock structure on it because the suspension, on its side, is not supposed to work that way and should be rebuilt completely if wanted to do so.

Would be easier to build than the four-five points pivot system? Perhaps... though I doubt it. All I need now is to keep the faith, be patient, assemble the truck and make good and precise measurements to design and build the best device to make the truck and the Box work together without any interference from each other.

Thanks again and cheers.


Pairoa

Hi Pairoa, have you tried to contact MB for a body builder handbook, MB have one for the Unimog with all the various options for mounting just about everything to the Unimog chassis, being a German company, I am pretty sure they would have detailed specifications of what you can and can't do to you truck. MY body builder handbooks had all the detailed dimensions of flex and distances from the centre of rotation I needed to make sure my camper frame would not hit the chassis or prevent it from flexing. I had a U4000 and a U1250 handbook, and they were very similar except for some of the constants in the formulae/

A camper body is like a water tanker, and I have seen some 6x6 MB water tanker trucks around. The mounting system from a water tanker would be a great fit for your truck, maybe you can find one from an old wreck somewhere.

I agree with you, you need to be able to use your truck to it's full capacity, I knew from day one that I was not building a show truck, and if it got a few scratches or dents from off roading so be it. Our first trip to the beach I had to push through some trees to get down to the water, and drive through a salt water creek and the occasional wave tp get where we wanted to camp for the night. It is meant to be driven and used, not just stick to dirt roads but to go off road wherever it can't and sometimes can't go. Just try not to roll it :)

Hello again. First of all... happy New Year to you all! Unfortunately the last year was not THE year but... life is hard.

Iain:

We then agree about what these things are made for. Good. I am fully aware that many scratches and bruises will be the cost for my way of driving and the use and abuse I will inflinge to the beast. Of course rolling over is not in the menu.

Regarding the frame, Mercedes manuals do not talk about flex or torsion of the frame with detail when referring to the NG class trucks and, believe me, I have seen them all. The Unimog has been designed to flex to the extreme and detailed descriptions on the issue are expected... and delivered.

Pirx pointed that the longitudinal axle of the torsion of the frame has to be in the center of the frame itself, but many things can prevent it to be like this, as the relationship between the crossmembers, the shape and stiffness of them, their location regarding the lenght of the frame and the location and type of the suspension and its supports, the presence of reinforcements of the frame, their shape and location, etc.

Subframes for NG tankers have all been custom made here so, if I decide to use one, I better build it myself. Though I insist, at least until today, in the free-torsion system.

Many greetings and thanks for your words.


Pairoa

Sorry. I couldn´t help myself. I like too much my country and like to show it everywhere.

Unfortunately the trip ended abruptly because of a crash and a few leaks here and there.
