Mack Granite Snow Plow - 42078 alternate model

[M_longer]

Yet another Technic set was sacrificed...

In short:
Parts from 42078 Mack Anthem were used for building from scratch another Mack truck, the Granite. It was created with using blueprints of real truck, within the given range of parts. Actually, it is a dump truck, with removable moldboard and sand spreader. It tows a quite unusal trailer, not seen on the european union roads, but used on US roads.

Let's start with overall look. It was supposed to resemble these:

And now with details, what we have here:

The truck is a Mack Granite, with three axle chassis and a dump body. There's no fake engine under the hood, but there are many other things packed inside.
And what is inside?

Openable doors, with cab interior and working steering wheel:

Of course there's Mack the Bulddog ornament on the front:

Elevation of the dump bed is operated by black bevel gear on the left side of the chassis:

Front moldboard can be elevetaed by turning black bevel gear on the right side:

Whole truck is quite modular, the dump bed is held in place by 4 technic pins, and sand spreader is held in place by two pins and axle protruding through dump bed:

And as we speak about the spreader; after placing it on the back, and adding the moldboard, the truck becames a true snow plow:

The spreading disc is driven by rear axle of the truck:

The trailer:

It is a tow plow trailer, quite unusual piece of winter equipment:

Model made from bricks has the two most needed functions of the real counterpart, which are elevating of the moldboard:

And four axle steering, which also sets the whole frame at angle:

These two manage to plow a snow quite good (but it works much better with bricks)

As usual for my C models, this one also comes with instructions.
They can be bought at Sellfy and Rebrickable:

Few pages from the instructions:

Comparison of A and C models (I do not have A model assembled):

Blueprint:

Bonus round; snow, a cat, and test model, built with different colour scheme:

Meet Rudolf the Cat:

Test model, which was used to test the instructions. This colour change required swapping of few parts (7L liftarms, instead 3L and 2L on the doors for example).
I wonder if its cab could be built in orange...

Now's the time for the LKP 0403...

Orange would be beautiful. C-model is very nice.

Awesome work! Although Rudolf the cat is my favourite part

Wow! I knew that Mack is a great set for trucks MOCing but yours... I wish there was a kind of Lord of the Rigs badge for you!

Does the trailer skew freely, when you just rotate the drawbar, or is there any actuator that makes is and keeps the trailer skewed?

There's a large linear actuator inside the frame.

Awesome work, can we have some day instructions of your underground equipment ?, they are fantastic MOCs even being old.

I am still considering it, because all of them will have their 2.0 versions, along with some new machinery, on that 14 teeth sprocket wheels from 42095 :)

We are thinking the same... today I have received a few but building without those new big L.A.s it looks to me very hard...

This is superb. I love the unusual trailer, and all the functions are pulled off very nicely. Great work! Will definitely add to my building list! :)

[Anio]

The model is good looking, the functions are cool, and the whole thing is very nicely built and designed.

You nailed it.

[BusterHaus]

Excellent C-model, I like it better than the main build. 

[Johnny1360]

Good job recreating the trailer portion, we have a few of those around here and they are amazing to watch in action. I have even thought of doing one myself but yours is so great I may just build it. I guess it's time to ante up and buy a second Mack Anthem set. Thanks for showing this well done MOC.

Awesome dude! To me this is the best mod/alternative yet. And I like the red and yellow version more, because of the vibrant colors.

This should have been the A-model. I would by 42078 set just so that I can build this.

Very very beautiful model. It does not look as a C-model, I don't see any compromise due to lack of parts. Very good job!

[WvG_853]

Thank you very much for the instructions! In the beginning I was hesitating if I should buy this set, but it has turned out to be a very rewarding set with excellent B and C models.

[sirslayer]

 your model rocks!!!! great job!! 

[Gabi_BC]

I have the unbuilt 42078 right beside me, i am seriously contemplating jumping straight to this version. Excellent work, i think this is one of the best C-model ideas i've seen around  here. 

[brickless_kiwi]

I really do like the test version in red with the yellow trailer. The colour just pop's!

I did see these in use in Toronto three way on one of the freeways.
