Introducing 42146 Liebherr Crawler Crane LR 13000 is the most expensive LEGO Technic set of ever!

After an early sneak peek, LEGO has officially unveiled the most expensive LEGO Technic set ever – the gargantuan 42146 Liebherr Crawler Crane LR 13000!

This massive LEGO Technic Liebherr crane weighs in at 2,883 pieces and is 100cm tall, making this one of the biggest LEGO Technic sets ever as well, along with an eye-watering retail price of US$699.99 / AU$1049.99 / £579.99.

42146 Liebherr Crawler Crane LR 13000 is available now to preorder now from, ahead of its 1 August 2023 release date.

If you’re pre-ordering the LEGO Technic Liebherr Crawler Crane, please consider using the affiliate links in this post. I may receive a small commission with each purchase that goes a long way in supporting the work I do on the blog.

This thing is just massive, measuring 100cm (39″) tall and 111cm (43.5″) lengthwise, and will be an absolute beast to display.

Just seeing it next to an adult male in LEGO’s promotional photos puts the sheer size and scale of the 42146 Liebherr Crawler Crane LR 13000 into perspective.

The set comes with 2 smart hubs and 6 large motors to power its functions (geddit), and has features such as tank steering, rotating turntable, luffing jib, winch and load-sensing features.

24 weight elements provide over 2lb (0.9kg) counterweight.

It’s definitely not for everyone, and I’m not a big Technic person myself, but it does strike me with a sense of awe and amazement. For Technic fans, or those into huge mega-machines, 42146 Liebherr Crawler Crane LR 13000 will definitely not disappoint.

Better start saving up!

42146 Liebherr Crawler Crane LR 13000 will be available from on 1 August 2023, and is available for preorder now!

What do you think of 42146 Liebherr Crawler Crane LR 13000? Do you think LEGO Technic fans will baulk at the price?

    This set is almost cool, but that being said, it falls far short of what I’d expect a model crane of this price to be. And for that reason, i’m really disappointed, and a bit sad. It’s a bit ridiculous, well the price is downright absurd. The price is around 3x what I’d be willing to spend on a kit like this.
    I’m not sure who the intended buyer is, but its not me. (It should be, but it isn’t). Full disclosure, I’ve worked in the crane industry for 15 years, and a lego fan for over 30. The LR13000 (the real crane) is an awesome machine. So i should want this… but i don’t.
    The chassis looks cool, and pretty accurate. I’m sure leihbherr was heavily involved in the design. The big drawback for me is that for this price, it sould have a lot more boom in it, maybe more luff. Too bad they didn’t. guessing they don’t have enough weight in the tray to balance the crane. Lego used to use weights in their floating boats.. maybe they should bring that back.
    Here’s the big disappointment; The real crane has a 54m derrick (back mast) and up to 132m main boom. Why would they sell it with such a short main? It is about the same as the derrick length. the real crane can have 108m jib, and looks like they have about 42m on there. Sure it can lift a lot more in this configuration, but it’s not at all an impressive build. How hard would it be to include extra boom? Again, this is probably due to the balance issue. Welcome to the crane world. The real crane has up to 1500tonne of superlift balast… guess you can’t match that with plastic bricks, haha. Lego is capable of selling large builds, like the Eiffel Tower. Maybe they’ll sell a boom extension kit. But again, would have to add some ballast.
    So close lego, so close.

    That’s not the most expensive LEGO set. The latest ucs Millenium Falcon was costing more.

  3. Ross Hinds says:

    This is a pretty incredible piece, would love it in my house. Unfortunately the price is an issue but if I could buy it, like all my other Lego sets, space taken by it, dust and all other issues would be waayyyy down the list.
    A real challenge to build it.

  4. Ryan Yuri says:

    Wow 👌

    Very nice. Only issue is the amount of display space needed lol.

  5. Goff says:

    I’m a bit of a Technic fan and I could afford this if I wanted to, but I don’t. Not at that price. Not a chance. The value’s just not there for me. And that’s before considering finding display space.
    Not to mention that a sieve like that will be a dust trap. Imagine trying to keep it clean and pretty.

  7. Scott says:

    It takes up a lot of space but is fairly hollow. While the functions are good, I cannot expect the build experience to be as good as a Ninjago city or UCS Falcon style set.

    Another stupendously large and expensive set that I wonder who the target audience is and why Lego made it other than to say “we made it”. You can get far more bang for your buck with dozens of other items from radio control cars to drones that’ll itch the same scratch and be far better value for money.

  8. joe says:

    Extremely overpriced. May be Lego wants to make up quickly for the lack of large technic sets for a few years now…

  9. Nick says:

    Now hang on Jay what’s he asking?
    ” Tell ‘im ‘e’s dreamin’ ”

  10. Jerry says:

    You can buy an equivalent Chinese set with more pieces and more electric motors… for a price under $200.

    • Roald says:

      I agree that 42146 is absurdly expensive. But, your suggestion goes for every Lego set. Buy the Chinese non-Lego version for significantly less. End result: Lego cannot compete in both price and quality, and Lego disappears. Not something that most of us would want.
      A more appropriate response is to NOT buy this set at all, but keep buying the more fairly priced Lego sets.

  11. Lavern says:

    Looks like a $350 set to me.

  12. Luís says:

    With 6 motors and two hubs, controllable only from a smartphone, it will likely be a huge disappointment, just like the 42100 was. I’d expect most LEGO adult fans prefer the complexity of the old Technic models, with only one motor and lots of gears to control the different functions.

    • James says:

      This set will allow actual crane control. As a certified operator, this is everything I was hoping for. Hopefully we will be able to run multiple functions at once.
