Сокол-80M crawler crane.

Recommended Posts

Some month ago, I discovered the Сокол -80M (Сокол = Falcon), a heavy Russian crane with a lifting capacity of 80t on a two stages telescopic boom, thanks to another couple of hour spent on Youtube instead of working. See the video here (starting at 1:38)

After some difficult search, I found that two variant exists, the first one is Falcon 80.01 and is mounted on a wagon for railway crash salvage and recovery, the second one is Falcon 80M which is mounted on a self-propelled tracked vehicle equipped with outriggers, able so to be also used in hard off-road environment . It is this version that kept my attention.

The Lego Version

This MOC is ‘inspired’ by the Сокол-80M more than a real scale reproduction.

All the pictures are availavle on FlickR

The transporter part is mounted on two track and equipped with deploying outriggers adapted from the 42009 Mark II Mobile crane. I had to modify them in order to avoid clash with the tracks

There is 4 functions integrated in the transporter:

  • Left track + Right track with a PF-L motor each
  • Deployment of the outriggers through PF-M
  • Extension of the stabilizers through PF-M

These functions are controlled by a SBrick and powered by a single rechargeable battery installed in the cabin.

The superstructure supports the main mast which is erected using two linear actuator. Due to the gear reduction (PF-L > short worm gear > 20T > LA) it moves very slowly but it works. I would really love to see one day Linear actuator twice the length of the current ones.

Superstructure is installed on a 60t turntable and integrates all the functions required to operate the crane:

  • Rotation of the superstructure through a PF-M
  • Erection of the mast through PF-L
  • Deployment of the telescopic part through PF-M
  • Cable operation through PF-M

These 4 functions are also operated through a dedicated SBrick powered by the battery. The only cable passing through the turntable is for the electrical alimentation

The transporter and the superstructure are independent and can be separated. The assembly is done by simply clipping the turntable onto the transporter.

Good and to improve:

Good :

  • It’s like a mobile crane but more badass.
  • Each transporter and superstructure can be controlled independently from the other

Could have been done better :

  • The visual aspect of the transporter and the crane cabin are not really perfect. I won’t lie, reproduce real machine at a mid scale is still not my cup of tea.

What could be done better:

  • Upscale it. Bigger, more space, more possibility.

Thank you for reading :classic:

To be honest I think I've just been lucky :grin:  

I don't exactly remember how I found this crane the first time. I suppose I had Youtube playing random videos and the "TU2-155 Delivery" one just appeared. "Oh wait, this is a cool thing to do with Lego!". After that it's the usual process: try to find info about the real machine, then plan, then specs etc. Not the easiest part when all website are in Russian.

Youtube, first source for inspiration :thumbup:

Same way I know about Amkodor machinery: the Internet. :laugh: A lot of their stuff would be great to MOC, especially their 333B loader as it has a lot of sharp angles. :sweet:

Also, I'm not an expert with Cyrillic, but I believe the Slavic word for "Falcon" is "Sokol" as seen here. Great build as well. :thumbup:

You are right with both despite the fact that under Cyrillic writing, red star...so-called antifascist made ethnic cleansing in Croatia and Bosnia and Herzegovina...but that is another story and that is not connected to @Superkoala who made great MOC :thumbup:

You are absolutely right here. Feel free to ask for help with Cyrillic if need.
