[MOC] Mini Mammoet Sk Series crane

[Aleh]

Hello and welcome my new crane. I hope it deserves a separate topic, bacause it's simply another crane :D

Implementaion of the world famous Mammoet  SK series ring crane in a small scale. The crane consists of ~1180 parts but reflects absolutely all real crane functions:
-Tower operating with double chain, forget about the winches here! L motor

- Slewing with 8 * 8 formula and L motor

- Winch with L motir and 1:5 reduction
- Able to hold the tower horizontally without anny additional counterweight
- Can load 500Gr - which is not the limit but alraedy great for this scale

All functions work smooth and easy. Small amount of parts allows to assemble it to a bigger amount of fans!

Looks cool! Probably not mini, but still big! Good job! I like the train wheels.

Ahaha, comparing to this it's tiny indeed))

But thanks for the reply)

Yeah, that's what I was comparing it to when I said it was tiny. To me, its still really big, and VERY impressive, especially the engineering.

Nice job.  It should be more accessible in this size for more people to build.  You even have a tiny operators cab.  You are missing the box for the chain to pile into though.  Do they use that on all the sizes of SK cranes or only the biggest ones?

I skipped it here intentionally because of the battery box location. Moving battery box to the fron part of the support leg will reduce the counterweight force and the crane won't be able to hold the boom horizontally without additional ballast.

And this box is skipped in my SK6000 because the chain got stucked inside often, So I had to refuse from that basket.

SK series includes only 3 monstersize cranes if I'm not wrong. Both the newest SK6000 and Sk350 have this basket for chain. About the rest models you can google my friend. Thank you for the comment!

 

 

Btw I think I need to update my signiture photo here :)

Nice crane! It looks great!  I especially like it because it is a rail crane. I think you did a good job on it.

Because of the high demand I added power up edition. Only a few parts needed to be changed + motors :)

Very cool crane and idea.   I think the "mini" title fits perfectly.  Even though it is >1000 pieces it is mini to scale of the actual beast.  

 

I have several builds on my to-do list right now but I wouldn't be surprised if I return to this and build it sometime!

Thanks) The original idea belongs to MAmmoet engineers, I simply implemented it of Lego Technic

It's mini not compared only to the original monster, but even to my SK6000 crane - that was the idea.

And do not postpone the build - I think it will took only a few hours to build from zero :)
