[MOC] Sandvik MH620

[M_longer]

From 16th to 18th September 2015 I was at International Copper Ore Mining Congress at Sandvik exposision hall. Yes, year ago. I was asked to build a model for that exhibition, and under 3 weeks this little thing came to life.
Now it is time to show this model, because it will be taken apart shortly :)

Here is how real machine looks:

And it differs from what I have build, because it is higly customizable and their look vary.

I did not had chance to put my model next to real machine, but here you can see it standing on the part of the rear conveyor:

Let's start with the looks:
The model has two sides, a "nice one", which was wshown to the public:

And uggl.... technical, which had lots of tubing and wires sticking from various places.

The controller:

Main feature (and something that gave me a headache) are the conveyors, which goes trough whole machine:

The main conveyor is made of 336 3L tread links and is driven by M motor. As an addition, the conveyor drives the loading stars, by set of bevel gears under the loading table:

Conveyor goes right under the turntable that holds cutting boom:

The loading table can be elevated and widened. Both functions are pneumatically operated.

Second conveyor (so called "tail") is mounted on z60 turntable from Arocs set. The weight of the whole "tail" started to bend frame of the chassis, so I had to put a small wheel under the turntable to prevent it from doing so.
Conveyor (270 links) is driven by M motor, and its drivetrain goes trough the turntable. It can be turned by single large pneumatic cylinder, which has enough force to swing it from side to side.

Stabilizng plate can be eleveated (two small pneumatic cylinders)

In theory this model has propulsion system, driven by L motor,  but at the end of the building process it turned out that is not efficient enough to move the model. But on the exhibition it didn't had too much room to move on the table, so it was not a big problem ;)

The bolting unit (that something on the top) is moved by M motor, which pulls two rows of chain links (172 of them):

The cutter boom, along with cutter head are mounted on the turntable moved by M motor. Its weight caused some bending, but I did not had ideas (and especially time) to improve it. But it worked :)
Whole thing is elevated by two large pneumatic cylinders, and the  boom can be extended by large 11l cylinder. Cutter head is driven by 47154c01.

And bonus pictures with TH5500:

It stood over a year on my shelf, because I did not had any will for taking pictures and making video of it. I was tired after that building marathon and it still was my first thought every time I have looked at it.

And it probably would stand there another year, but all my my Sandvik models were at Sandvik meeting and it was a last chance for taking a pictures of it in one piece, because it returned to mie in pieces (and is taken apart  gradually)

As usual, I'd like to thank Sandvik for providing me documentation neede for making this model.

Wow, it looks fantastic! It's so smooth and still so many functions

And the remote is frightingly awesome

[Paul Klop]

Very cool build!  I saw it yesterday at YouTube and I like it very much. It's a pity that it cannot drive due to the weight 

[Leonardo da Bricki]

Great model! It looks terrific and still has a ton of functions. Nice job.

[Edwin Korstanje]

This is what model building shoot look like.

[Minique85]

This is a really beautiful model, very detailed yet full of functions. It's really great to see this type of machinery rendered in LEGO. 

The whole thing in three weeks, speechless .

Really cool 

[Boulderer]

I'm amazed at the 3 weeks! How do you get all the pieces together in that time, nevermind design and build?!

[LucyCol]

Amazing build, I think it's all the better for having a separate control unit.

It was built with using pieces that I had in that time, and I have made only one BL order, for few white tiles and 3L links.

I have over 100 000 bricks, so I am not making BL orders too often ;)

That would certainly help ? Though it must take very efficient sorting to allow you to find pieces quickly.

Actually, my sorting system is now is use, because I have started major sorting, including "all-the-boxes-that-I-have-put-somewhere". All sketches are also taken apart (some of them are even few years old). I hope that I will have all my pieces sorted before 2017 starts...

[Edwin Korstanje]

Congrats Marek with the front-page.

[AFOLegofan66]

very impressive piece of Sandvik equipment built in Lego. So many functions in a relatively small package...nice photo shoot BTW.

[Ben Andrews]

good lord. and i thought making a chairlift, series of waterfalls and a water wheel was a good challenge! dude.. great effort and fantastic result!

[JJ2]

Wow it's amazing you built this in 3 weeks, to bad it cant move but its more of a display MOC so that fine.

[M_longer]

All of my Sandvik models have been taken apart. At least now I know why MH620 has lost its drive :)

And it was right under L motor, here:

Well you smashed that gear for sure... :-)

[BusterHaus]

Haha, it's as if you've performed an autopsy.  It was a beautiful model, thanks for showing it as well as sharing the aftermath.
