[MOC] Mammoet SK6000

[Aleh]

Hi Eurobrickers!

I'm back with the new MOC - this time it's a new Mammoet SK 6000 crane! Current configutation is Mammoet SK6000 + Mammoet SK350 Fixed jib (which is compatible in real life)

Original ring crane was just recently released by ‪Mammoet‬ in Netherlads! This is fan work. For built used only open source resources from WEB! Ok, also this MOC was built with unofficial consulting with Mammoet engineers, because it was a lack of the info in WEB, so I have to ask some thiings to match the real masterpiece crane.

UPD: I was invited to the real crane's world presentation on last (or prevois) Friday to the Netherlads with my Crane MOC to show it at the mass media day near the real SK6000! Unfortunately I was on vacation that time and lost this once in a lifetime chance..

 

How it works: Centered counterweight is fixed and non movable, around it there are two train racks (imne are almost 180 degrees), so the crane is rotating arong the ballast. Real SK6000 does not have it, but from SK350 I took the jib which was surprisely fix and not luffing - it has no adjustments. Machine is able to lift 6000 tons and lift 2000 tons at the lenght of the footbal field from the basis !!

The main feature of this crane is that it does not use winch to operate the boom - it uses special mechanism with chain, so I implemented this also :)

Please enjoy the video first:

 

Built with genuine Lego technic parts + 3rd party strings + ‪2 BuWizzBrick‬ 's. I refused using trixbrix curved rails because found a solution with genuine lego parts.

The model has 7500 parts which makes it the biggest MOC in my career!

It has 8 L motors for smooth operating, powered by two buwizzes.

Crane weights 8,3 Kg excluding power sources (battery boxes) and counterweights!!

And the height is about 2.3-2.4 meters.

Building instructions already available. Built took 1760 steps, which required a lot of effort to prepare it. https://rebrickable.com/mocs/MOC-195537/OleJka/mammoet-sk6000/#details

Scheduled to be frontpaged.

[Alex Ilea]

Wow, this is an absolutely insane build!

[Axadder]

Linked chain system seems to be quite impressive! As well as the overall building.

[2GodBDGlory]

Wow, impressive! Not only does it have size, but it has some interesting mechanics with the chain

THAT.IS.HUGE.!!! Respect!

@Alex Ilea, @Axadder, @2GodBDGlory, @MAP Tec Thank you guys! I really appreciate you read the entry post/ watch the video!

Cranes's size was based on the carriers size :)

Bro, this is MASSIVE! I only wish I had enough bricks to actually build it lol.

What a huge masterpiece!

Amazing video and totally cool work!

Totally not my cup of tea, but DEAR LORD - this thing is massive and most important works like a charm. I cannot find words to describe how awesome it is, hands down, great work!

Hello! I forgot to show off about the main point of this crane. As I wrote in the initial post - I was unofficially consulted by Mammoet engineers and... I was invited to the real crane's world presentation on last (or prevois) Friday to the Netherlads with my Crane MOC to show it at the mass media day near the real SK6000! Unfortunately I was on vacation that time and lost this once in  a lifetime chance..

Let's keep jokes aside - now's the time for real load :)

A great build and works great too. Wel done.

[Lego Tom]

Most excellent!!!  I bet that took more than an hour to build! 

[Aleh]

Hi, here are the most "technical" renders which help you to understand how it works:

Chassis - one motor for each 12 wheels:

Winches - the main winch has two pairs of gears. You can play with them to adjust lifting speed or torque.

The most demanding part - boom raising mechanism:

Comparison to my Mammoet PTC-200 DS:

Nice mechanism pics! May I suggest that next time, the background is a lighter color? I had some trouble seeing the complete mechanism, especially the black parts.

DEAR LORD THAT THING IS MASSIVE, Respect Brother

@bruh, @trucks3 Thank you for the kind words guys! And yes, next time I'd change black background when there will be any black parts on it :)

For me, this is the core of what Technic is about - functional models that work like the real thing. I'm really inspired by giant cranes like this one. Someday I will build one of my own...

100%

Definitely agree. Technic is literally made for engineering, and this showcases it very well. Also, thanks for the note of color change needed
