[MOC] Iveco T-Way Tipper 8x4

[Ngoc Nguyen]

After I finished the 42128 B Model Dump Truck a couple of years ago, I wondered what I could build with no part limitation. I wondered what an ultimate dump truck would be like. Then I saw the Iveco T-way, and the way it oozed coolness and ruggedness struck me immediately. I came across the Iveco T-way MOC by technicproject on Rebrickable first, and I made some further research into this kind of truck. I knew I had to build one myself, and I set to push this model as far as I can. Let's see what I've managed to accomplish.

 

 

The real life vehicle that I used as a reference is this one.

 

The bed is based on the one in official photos.

 

As for the features, since I want it to be the ultimate dump truck, it definitely needs rear duallies. Thanks to the new half 30mm rim and the half 49.5 tire, which for some reasons has only appeared in 5 sets so far and has not appeared in Technic, I can set the scale on the 49.5 tire with proper dualies in the back. Differentials and an inline 6 engine and a tipping cabin are all a must at this point. Since the bed has a side ladder with a second stage, well why not give my model the same thing. I used the ladder design in the Defender as a reference.

 

 

The main function of a dump truck is the dumping bed, so of course my model has one. At this point I noticed that there's a gap in the middle of the chassis, between the 2nd and the 3rd axles, so I wanna put another function in. The original idea was either a 2-gear gearbox or a 4-gear one, but they didn't really interest me. Besides, I don't want to have to tilt the cabin every time I changed gear. So I put something simpler instead: a park gear. This idea is taken from the gearbox design of the set 42114 Volvo Hauler. Also can't forget those wheel chocks for extra safety.

 

 

Everything's cool so far, but I wanna challenge myself further. Since recent sets of this scale, like the Jeep or the 6x6 ATV, have suspensions, I wanna try incorporating their designs into my model. And the result is spring-loaded pendular suspensions for 2nd, 3rd, and 4th axles. Yes, spring loaded even. How do I squeeze 4 springs into that area above the rear wheels? Buy the instruction to find out. 

And yes, the 2nd axle has suspension too. That means I have to make it steerable while having suspension, and not just that, it needs to have a smaller turning angle than that of the first axle too. And I succeeded in designing that!

 

 

At this point, this set is already packed with functions. But I'm not done yet! I still remember the old motto of Technic sets (I invented it myself): If you like it then you put a crane on it. And I know what you're thinking. "Where else do you put a crane?" "Doesn't the bed take up the whole space already?" Well, wait for it.

 

 

In the real truck, there is a hoist that allows easy access to the spare tire. We found the crane in a craneless place! Also, the gray bar is actually movable in the real truck. I didn't know that at first, because the bar is up in most photos and videos that I found about this truck. It was not until I checked the brochure and saw one exact photo with the bar lowered that I was aware of this feature. Apparently it serves as a foothold that allows you to climb up in front of the truck's face.

 

 

This next part is not about the function, but about the cabin, which I spent quite some time on. I tried to put as many realistic details into the cabin as possible.

 

In the left photo, you can see the side view of the cabin from the driver's side. You can see that I put two vertical bars in there. They actually exist in the cabins of many trucks, as they help the drivers climb up. The driver's seat usually has a portable control panel right under the seat, so I used the pin hub and axle connector to represent that. You can also see the two pedals under the steering wheel. There's also one stick right below the steering wheel, and another stick to the right side of the driver.

In the middle photo, you can see the red connectors between two seats, and the red liftarms in each of the seats. They represent the red safety belts that actually exist in the real truck.

In the right photo, you can see the middle dashboard with aircon filters.

And just like in some real licensed Lego sets, there should be a comparison photo that shows the Lego model and the real vehicle side by side.

 

 

Overall I'm very pleased with what I've managed to achieve with this set. I like what I'm seeing, how about you?

P.S. Too bad I couldn't book a photoshoot due to my current schedules, so I had to use renders. But that doesn't mean that I haven't  built the real model. I did built the set and have the real thing next to me.

[Good old Lego builder]

This looks great! Well done!

[jorgeopesi]

Nice dump truck, what is the final angle of the bed when is raised.

 

[Paul B Technic]

Very nicely done.

The bed can be tilted by about 9 degrees. That's one of the shortcomings of this, but that I'm willing to accept.

The cause of that small angle is that the linear actuator is put in front of the bed instead of under it. The reasons are that one, that's the setup in the real truck, and two, in my model the area under the bed is occupied by the rear suspensions already.

[Jurss]

This looks good and also detail level is really amazing.

[Jundis]

In this scale, the details are amazing! Personally speaking, there are too many details for my taste :D

I'd love to have a pneumatic cylinder with telescopic layout :-)

 

[karmadrome]

Fantastic looks, great functions and superb presentation! I especially like the parking brake here. You nailed the cab really well, and I especially like the obligatory cup in there, just like in City trucks ;)

I like the parking brake too. It's a small addition but a very intuitive and effective one.

When I saw the new micro panels in the Bugatti Bolide I knew I had to use them. The micro panels and the panel extension paper roll fit the face so well there's no other way that I can constructed the cab's face.

[thekoRngear]

TBQH, it looks yummy! 

[gyenesvi]

That's looking really nice, and you squeezed in a bunch of nice functions in a relatively small scale, good work!

If the 42043 can have that level of details then there's no reason my model can't!

I'd love to have that telescopic cylinder too. Without it the tipping angle is quite small.

I suppose they're aesthetically questionable, but maybe the new city worm gear could be used for a decent amount of linear actuation. Since you can just keep stacking them, you could have 16 stud worth of travel from 3, fitting in about 18-19 stud vertical space when compact.

That's also the problem in addition to the aesthetic one. The distance from the base to the connection point of the bed is only 11 studs. If I had 19 studs to spare I would have put the XL linear actuator in that place already

It is very sad to see that you did not mention another Iveco T-way as a reference for your model.

In the past, after purchasing the instructions of my model, you asked me to publish a revised version with openable cab doors (I allowed you to publish the cab mod instructions, and not the whole model). Now I see you made a new model and that's ok, but the similarities are obvious, so I did expect you mention me, at least.

The way you describe some features of your model (which are taken from mine) is simply not polite.

 

That said, I like you version and the only bad point is the very limited tilting angle.

As I want to avoid any similarity and possible conflict with your model, I developed mine from scratch. I tried to make the features as different as possible.

As for the thread you quoted, it was posted on Feb 3rd 24. At that time I already finalized my design and was waiting for parts to arrive, so any resemblances are purely coincidental. The only creation of yours that I had access to is the version you published on Rebrickable. I bought the instruction of it at the end of 2022, but as I started working on my own version I no longer consulted it.

Please elaborate which feature that you consider is taken from your model. Given that I based the model on the same vehicle and on a similar scale, and there are limits in part choice, some similarities are unavoidable. If I recall correctly, the only part that I adopted from the Iveco you published on Rebrickable is the solution for the front lights, but even that I made them tilted to differentiate. As I said, I tried my best to make the features of my model as different as possible.

As far as I know, the functions that your creation has are dumping, and pendular suspensions on 3rd and 4th axles. The model is a dump truck so it must have dumping. The design solutions for pendular suspensions on 3rd and 4th axles have appeared in a couple of official Lego sets already. Also, in my model the suspensions are all spring loaded.

Thanks for the support regardless. I tried to squeeze the XL LA in there but there is no space. If I get rid of the suspension on the 2nd axle there might be some more space below, but I don't wanna do that.

I was referring to the Rebrickable model, not the thread itself, which is just my motorized mod of the Rebrickable one. You did not mention it at all.

We both made an Iveco T-way so that's possible that many parts are similar, that's not the point. But it is clear (you have my instructions) that there was an inspiration to make your model, and it is sad that it is not stated in your description.

The dual wheels on the rear axles using 49.5 x 14 wheels look like it is your own idea! I'm not saying I'm the only one using them... but hey... 

Fuel tank, hydraulic tank, spare wheel, ad-blue tank, mudguard design...

I have added an acknowledgement to your creation.

They all appear in the real life truck, so I can't avoid their inclusions. Even then, my execution were different. As for the details:

- The fuel tank and ad-blue tank in your creation are 3M tall. Mine are 4M tall so that they fit the proportion better. Also, in the real truck their knobs tilt outward, and I replicated that feature.

- The hydraulic tank in your creation is brick built. Mine uses Technic pieces

- The mudguards in your creation don't have side orange lights, while those in mine do. Not to mention, it was a real challenge to squeeze that piece into the mudguard of the 1st axle. The first axle's mudguard in my creation also comes in two separate pieces, just like in the real truck, to accommodate the tilting cabin. The mudguard for the 3rd and 4th axles have wheel chocks and the pins that hold em, while those in your creation use 3x6x2 L panels, which don't accommodate those things.

... panel curved 3x13 on the front-top ot the tipper, to simulate the tarpaulin... 

Let's end the discussion here.

I accept that a Technic airplane does not fly but I do not understand that a Technic dump truck can not do its primary function but it is just my opinion.

It can actually dump. It's just not good at dumping.

I didn't dare to say that, but as it's said now, I'd like to consent.

We all know the struggles and challenges when building with Lego Technic (especially in this small scale given the available Linear Actuators) (and we all love them!!!)... but dumping with an angle of 9 degress is a little bit low. Maybe some round pieces will roll down, but most of the load won't even move at this angle.

This is even worse as Ngoc's MOC is really well engineered and looks great and has a lot of nice features apart from the dumping issue.

In general, this model is designed more in the approach of a shelf queen, like the Porsche 42056 but for a truck, and since I rarely play with models, the limited dump angle isn't a problem for me. However, given you folks' comments, I've given some thoughts about this, and I think I'll have to fix this.

I'm not sure yet how it can be fixed or if it can be fixed at all without a total rebuild. But for now what I have in mind is that I'll get rid of the suspension on the 2nd axle, which may create further space below, and I'll squeeze the XL LA into it.

Of course there's always the traditional solution of putting the LA under the bed above the rear axles, but I have already done one model like that (42128 B model) and second in the current setup the rear axles have springs that don't accommodate the LA.

Having said that, I'm not gonna go back to this model any time in the near future. I've spent more than one year on it and for now I wanna be done with it. I also have other fun mini sets I wanna work on.

So I tried to put the XL LA into the thing, and boy it does not look good.

 

The problem with LA is that it doesn't come alone. It must be accompanied by the LA holder, which in reality extends the total length to 17 studs. And it digs so deep that it's right above the floor line, which means it will interfere with not just the steer axle but also the drive axle.

[Ngoc Nguyen]

I wanna share a couple of design solutions that I managed to come up during the design process. I hope it can be of use to fellow truck MOC designers.

This is the drive train and steer train.

 

To make the second axle both suspended and steerable, I used the setup from the 42043. And to make sure that the steering radii are different for each axles, I geared down the steer train to the second axle.
