Semi dump truck

[steph77]

Hi eurobrickers

This is what we will talking about here: a mini scale semi dump truck based on a Mercedes Arocs 6X4 and a solid tilting bed mounted on one 3 axle trailer.

This time I decided to keep it small. My son asked me for something simple this time but fun to play with. So I do.

I worked hard on the design of this little set. The smaller it is hardest the design is I found. I am however quiet happy with the end result.

From the front view you can see I choose a contrasted color scheme for this truck. Regular blue frame, white cab and black to simulate the plastic covers and accessories of the cab.

I place light, traffic signs, rear view mirror, antenna and gyro on the top. All we need to make it look good, as in real life model.

The top view show the roof treatment. This part was particularly hard to find. You have a discreet HOG, the security roof trap that opens and two small panels to finish the roof line

Viewed from the back you can see I managed a space for the rear window, exhaust pipe, spare wheel and a toolbox. I do not forget the back lighting with one projector but also rear stop and traffic lights.

The 5th wheel is a simple pin connection. I found another system (mechanical lock) but it doesn't match perfectly the scale of the model so I decided to remove it.

But there is something more about this cab...it tilts and the doors can be opened showing the interior with two seats and steering wheel (not it is not operational )

 

The complete model is 36X8X11 cm. I am particulary satisfied with the proportion of the whole thing.

Rear view of the trailer, same detail attention than for the tractor unit. You can see at first plan the locking system of the bed's door (simple friction pin).

 

And here is the view of the railer once lifted. The mecha is dead simple: one linear actuator in direct link with the HOG place on a real ergonomic place. Few pieces, great playability.

The trailer as also a retractable parking support with simple linkage command and lock point to assure it's stability.

Here it is:

But that's not all. I manage the all wheel one good ground clearance as my son play with it on it's bed (often by night ) and I realized a quiet complex pendular suspention on all axle.

The system is based on Pippasseyeyoyo's one developed on his own semi dump truck. I just scale it down a little .

Suspention in action. the first axle is rigid on the tractor unit

 

So here it is...do not hesitate to comment it and any good idea to improve it is welcome.

Steph.

nice design for this size, I really like the tipping bed and the clever design for operating it.

Thats awesome, i really like small models and so much functionality. Incredible.

May we get a belly shot? The suspension sounds interesting

[suffocation]

Awesome work again!

[Jeroen Ottens]

Great model. The proportions are just spot on.

I really like the way you balance between functionality and aesthetics. I know that making designs look good in a small scale is even more difficult than on a larger scale, but you pulled it off beautifully.

I just day: Each MOC from you would be and would deserve to be an official set of TLG... the crane truck, the rubbish truck, this little and cute one - just awesome and fascinating building skills 

[BrickbyBrickTechnic]

Like all your MOCs, this one is just so well done. Great job!

Nice linkage and truck  .

Your son must be spoiled with all these excellent mocs!

As it was asked for here are two pictures of the pendular suspension system:

Such clever solutions and details everywhere, again a true masterpiece proves that small is just as great as bigger models.  

I admire your skills, hat off.

Wow the solutions are ingenious. 

[AkiyamaWataru]

I'm sorry @steph77 but this is not a pendular suspension. Your's is a bogey system. But I like your Truck an Teailer very much. Wish I could build so well...

This is a very well done build. Nice functions and a very eye catching color scheme.

Someone did something nice with 42025  !!!

If anything Technic ever had a hope on Lego Ideas (I get it.....not likely) this is what I envision would.  Great looks, great functions....this really is the whole package......

Awesome MOC, I am amazed at the functions included in such a small model. It looks great, and the suspension is really good.
