Hi, thank you for your reply, i was thinking to use XL motors for drive and rotating boom due to it's torque and slower Speed (the boom rotation Is too fast for a Crane like that). There are many empty parts in the structure, maybe it's tricky to keep It strong as It Is now, placing all the gears inside.

For the overstructure, i would try to use One XL with a gearbox that switch between the three functions.

For now, i have to finish the set, but i'm sure i'll be tired of c+ soon.

Anyway, big thanks for your help.

 

Im not sure if I remember correctly, but PF L and PF XL have the sane torque output. What makes L easier to use is that its form factor allows it to be integrated more easily into existing structure. To accomodate an XL you effectively need to clear out a 5x5 space.

According to filohome site, XL motors has 4x more torque than L motors. That's why i tought to use that, even if it's volume can be more difficult to place inside.

It actually has only 2x according to his website. It has 4x the output of the medium motor.

Yep, i confused M and L.

XL has still the higher torque.

Yeah. More torque = more better!

Kudos to @Marno,  @Minitiguan, @Legotom, @R0Sch, @riverprawn  for sharing your MOCs. I went for an extra two box sections in the main boom. Doesn’t make it match the real thing, but it’s an easy way to improve the proportions. 

With reference to the iconic Liebherr 2012 product demo, it’s lifting another crane - set 855 that I got in 1977. My newest technic set lifting my first ever technic set! Technic’s come a long way in almost 50 years: 

Unfortunately I don’t have the time for any major mods - but that rotation gearing needs reducing!

Inspired by @vanczakp and his V-Frame idea, I build another one for my moc. 

I want to design the "V" in the back section and use two actuators, instead of one.

Because my crane most of the tine stand on a shelf, I decided to use a manual mode and not a motorized one (I had also no idea how to combine / add another motor in the original Lego app  )

Love that V Frame....do you have more details or instructions how to rebuild it?

[Minitiguan]

@Chrizl, I am selling this instruction on Kleinanzeigen ;-)

Let there be light!

@Lego Tom Those light look great! I was thinking of installing some lights myself into the non-modded version as well since I can't find a lighting kit online. Did you buy all the lights separately or did you use a standard lighting kit? Thanks for any info!

I bought them separately.
