42081 C-Model - Log Loader

[M_longer]

My third attempt on making one set MOC. This time, the victim was 42081 Volvo ZEUX:

As usual, the final effect is something completely different that was first idea for it.
Parts used: 910 (of 1167) from 42081. I have been quite surprised when I have realized that 42081 is missing some core Technic parts, like gears (it only comes with x2 Gear 20 Bevel, x4 Gear 12 Bevel, only ONE Gear 20 Double Bevel and eleven Gear 12 Double Bevel). Which is, to be honest, almost none, when compared to total amount of over 1100 parts.
It is also missing, for example, these ones:

And that's the reason why I had to think twice before I have used specific part while building.

The first idea for alternate model for this set was forest skidder, but when I have made first sketches, it became obvious that there are not enough parts for making a model that will fit my standards.

After that I have started looking trough my folder with inspirations and I have found this:

And its shape and functions fit perfectly for restricted pile of parts from Zeux

So...

The model has 3 manual functions, operated by knobs on the back and on the arm. It also has pendular suspension on rear axle.

Overall look:

The arm can be lowered almost to the ground, and elevated high above the cab:

On its end I have placed a claw, operated by that z12 gear on the side of the arm:

Steering is operated by knob on the top of the hull:

This mechanism uses that "The Only One 20 Double Bevel Gear", because it needed some reduction for more comfortable use.
The last function is pendular suspension on rear axle:

And here you can see how it works:

If someone would like to build this loader, I have made instructions, which can be found as usual on Rebrickable and Sellfy:

Instructions are divided into several submodels, like cab, arm, chassis etc.

My alternate models of 42054 and 42081 (both made for log handling):

All of my C models, including the one made from 42043:

All of my models get test models, which allow to test the instructions, finding errors and adding some adjustments. This one also have them first made by me:

And second one, in different livery, made by @Bricksley

He also had 42080, which allowed to make this comparission shots. Thanks again!

Honestly I find that this model could be perfect official set to allow us to get tractor wheels for smallest (possible) set price because it is not including Volvo bucket. It has all main functions for such vehicles (if we ignore drivetrain)

We can say, this C model is made according to Your usual high standards, Bravo!

Looks very nice and complete. The fact that you added suspension makes it even better.

Assuming that would somehow be an official set, as was pointed out - without buckets and maybe by replacing steering hubs with default ones - we could get that set like 30% cheaper or even more..

Anyways, gj

I recognize all the difficulties of work and I regret that it is still not fun for me to do...

Well I have to say, that looks very good and I am quite impressed that it is a C model using more parts than most B models. Thanks too for the instructions, I may actually give this a go, I like it very much and it appears to be very well built.

I like how you made mechanism for claw. I plant to build skidder out of this set so I will definitely get inspiration from your model.

Good luck, I've tried the same and I was not satisfied with something that started appearing on my desk.
