This is a perfect opportunity for a third party company to make metal counterweights for the crane, as well as a light kit and even a boom extension kit that includes lengthened strings.

I very strongly disagree that it is worth 700 for most people. I think the set is cool despite its many problems but I would not pay more than 450 for it.

These Lego 'influencers' are surely going out of their way to defend this price.

It has some clever design solutions, no doubt about it, but there is some discussion about whether this really looks like a Liebherr. The wider tracks would have fitted the scale better, and the boom/jib combination chosen for this set apparently doesn't actually exist in real life. Might have been better to just release this as "fantasy" crane, drop the licence fees, and have a more reasonable value for money ratio. Regarding the issues with this set, someone suggested, looking at the set number, this was intended for 2022 release, but got delayed due to issues. And in the end, got released 95% finished basically. That could explain some of its problems, and maybe they had to increase the price because of the extra time that went into its development, due to the problems.

Yea I still can’t understand how tf plastic pieces and motors are worth 700 bucks

This set will be on 40-50% sale in less than a year.

How much Kool-Aid have you been drinking????? We are talking about a few pounds of plastic that cost mere dollars to produce. Even $500 would be WAY too much!!!!! You can get a Mould King 17015 that is twice as tall and has more part for under $250. Why would anybody in their right mind drive the MOST expense set through water????

Love the review, and I love that you test most if not all your technic sets outdoors. You live in such a beautiful area

Buying this would fulfill a fantasy of having operational scale model cranes. I'm not even sure i'd play with it much, and since you pointed out some of the annoyances I think I would find myself dissatisfied if I were to buy it. Reminds me of going to a furniture store, buying something that looks great and seems operational, but when you get it in your house you find out how poorly engineered it is.

$700 absolutely no. $550 reasonable. Btw, my country (Malaysia) already got 10% discount on August 1st release. 😀

I disagree with whose who say this doesn’t look good but although I’m really impressed by the technical solutions I can’t find aaaaaany reason for this to cost 700€. It’s crazy. Someone (Sariel) said that at least without the Liebherr licence (which it’s useless as it doesn’t represent any of the possible configurations of the real crane) it could have been cost a little less, but it would have still been overpriced. It’s really a miss for me, and I own almost every Technic set ever made 😢

For your info, anything that is denser than 1000kg/m^3 will sink in water provided it's displacement is not high enough. These counterweight pieces are just made of solid ABS with a density of about 1200 kg/m^3. I made a CAD model of the part and the 41g wright checks out.

Too expensive, crawler base needs to be wider, carrier rollers need to be closer to drive sprockets to aid stability, those white balls need to go, needs Derrick ballast, needs atleast another section in its main boom, hook needs about 20 more pulleys, track pads need to be smooth, it’s just so far from the real crane when the 9800 and D11 were very close,

You are paying for about 1400 pieces of mostly pins and short axles. The rest is the crane. It is definitely not worth what they ask for.

2900 parts, 1400 pins and axes for 700$? You mad? It's maybe 320$

@Unbrickme Great review! Looking forward to see your MOC video on this! Hopefully you can address the track issue and those ball things dragging on the ground. I also think they chose to go with fewer, larger frame parts for strength. Using lots of smaller parts would cause the superstructure to flex more

0:50 i really dont like how you turn the pages

It won't ever worth 700 bucks!!! That's not a Liebherr lr 13000, the real one would be way bigger in that scale with more weight at the rear. Lego will raise the price till the customers buy it. That's just marketing!

Could you take a Dremel and hollow out some of the counterweights and put in chunks of lead or lead fishing sinkers to increase the weight of them? I might try that when I finish the build and play with it a bit. Perhaps some water soluble white glue could mitigate the problem with the counterweights falling off and coming apart, and can be removed, should one have a change of heart.

@Unbrickme Where can you get boom parts to extend the length of the boom? I would really like to add some height, but BrickLink does not appear to have any, unless I am missing them on the site.

@Unbrickme Is there a way to revise the gearing to slow down the turntable a bit?

Mechanically, yes it's a good set in that department, though they should have just dropped the license because at the end of the day it does not really look like what it's trying to portray...

String has and ALWAYS will be my nemesis with my sausage fingers, so the tutorial video was pretty darn helpful! While I do say the Lego Technic version looks NOTHING like the real thing, it is surprisingly fun to play with!

Crawler cranes arent designed for "off roading". They're designed to be operated on level stable ground

Always appreciate and enjoy your reviews 🎉

If i ever get this set either brand new or second hand id add on a derrick ballast as it seems that it always tips over I just still really want this set its brilliant Just got a cool idea for weight at the back so instead of the counter weights build a box and fill it with coins or something heavy and it will weigh more at the back i mean like 1-2 KG at the back

$700.00 is a non-starter for most Lego fans. If you have $700 to go on a Lego shopping spree you can get several sets and have some money left over for lunch.

Can you try the shock absorbers on a vechicle? It would be interesting to see how it will drive across off road terrain

To me, the value of a big set depends on the number of alts that will be available over time. And I think there will not even be half alts for this compared to the R9800. Too little variation in the parts, cranes are the only builds. So no, not valuable at all.

Way too expensive and big for me. I think LEGO should focus more on Technic sets that aren't cars. Oh and making this crane look like the real thing would've probably increased the price but $700 already feels too expensive to a lot of people.

the pricepoint and authenticity is a total dealbreaker for me, lego technic flagships are supposed to be challenging but fun, like for example lego 42100 or 42114, which were both jam packed with functions, i fail to see any difference with this and 42042 which is actually more advanced due to it's gearbox, then you have 42100 (also under Liehberr branding mind you) which had twice the amount of pieces and a more diverse and bigger motor selection (at 7 motors as opposed to 6) for only a little over half the price as 42146, I can't conceivably say this a good deal by any metrics but thanks for your input on this set

Just wait for discounts and soon enough prices come to 450$😂

You can't add a weight in the app since it would be infinitely impossible unless you had a load line sensor because booming down would make it look like more weight

Im building my first lego technic, the sar helicopter with my 5yo assistant. So far looks good, people who designed it are very talented

Awesome review! Where are you going to keep this monster?

Derrick ballast wasn’t added probably due to the derrick mast itself being too short, meaning that a counterweight tray cannot be hanged vertically.

I love the set. BUT I HATE THE PRICE!

I wonder if you could try removing the support balls since they end up dragging along the ground. The counterweights don’t seem to make the crane tilt backward, so I don’t think removing them will affect stability. I guess LEGO put them there to account for those who might not be as gentle on the set.

Woah, I know im late but, a top 10 lego technic crane sets video wouldnt be a bad idea! (But i think we all know which crane will be coming 1st)

Throw out two of the motors, and insert a gearbox which one motor drives the function and one motor switches the function, you could lose one of the hubs as well. And use the correct track pieces from the D11 CAT set. And have an extension set for the boom ready at launch. And lower the price to 450 euro. Then it will be a good set and I might pick it up when it hits 250 euro.

I will buy it eventually. The price in Canadian $’s is a little steep. But looks like it is worth the extra. 6 motors a 2 hubs is great 😊 Where are you from?

hey unbrickme is it good for me to go from 42132 straight to 42115 cus i might get one in september

I put mine together last night and it is absolutely huge!! These videos do not do them justice!!!

How long will it work though? My bucket wheel excavator and roller coaster stopped working. Don’t exactly feel like taking them all apart and putting them back together again.

Ok this set might be really cool and everything, but it costs WAY more than it should.

I have already ordered my set :) Thank you for the nice video review.

7,36 true. also bad is the fact that the whole crane tilts like crazy. there should be more counterweits on a platform behind the crane. So that only the hub lifts up within limits of the tilt mechanism. The whole crane moving being part of the design is odd.

Great job on the video UnBrickme! Too expensive for my tastes but it does look like an awesome set 👍

it hurts to see how you treat it, it's not designed for water, it's designed for 2 kg or outdoor sandy and gravelly soil

I've always thought if the main jib was 1 segment taller and the counterweight was plates that sandwich ball bearings to of added even more weight, it would of least been close enough

700 $ for a few kilos of Plastic... Sorry but it's just not worth for anyone that doesn't make very good money.

Nice Review, just want to ask if it's possible to add more Truss to increase the height like 42042, i hope you will try that next time, tnx

You cannot gauge price per piece with this set...the pieces are freaking huge so the amount and complexity of the plastic you get is way higher than most other sets.

I love how you test these construction machines out in their real habitat lol. That's some proper reviewing that can't be done in a studio.

I really wonder what kind of giant LEGO Technic heavy machinery LEGO might release after 2 years, I hope to see a John Deere combine harvester. How about you @Unbrickme, what kind of LEGO Technic heavy machinery would like to see next after the 42146?

I disagree with your assertion that putting an actual weight in the app instead of a relative load "is actually a very easy program to make". Putting a hook weight on it would depend on it knowing the current angles of the boom and the jib, as well as the amount of counterweights. counterweights would be easy because you could tell the app how many are on, but the app would need some kind of sensor to determine the angles of boom and jib.

Regardless of the negatives, it looks like an awesome toy for indoor play. This 60 years old kid just bought one. Thanks for the awesome video.

Please create that modification video!! I want to see it with longer booms.

Hi, I love all of your videos. You do such a great job and I like your attention to detail. I love Technic. Gary from Red Deer, Alberta Canada

Would be a fun project to 3d print some counter weights that can be filled with sand or water.

its unfortunate that its so expensive, i was excited as i had expected it to be 450

Loved the video! Wish I was good enough to do a set like this.

Now that’s a set I need, great review!

It isnt worth it. Half of the pieces are only pins and other little things worth about 30$. It doesnt look like any Liebheer crane. The battery boxes are just open with no covers. No gearbox, just for every function one motor which is dumb. The only reason why this could be a liebheer is because of the many stickers, nothing else. The counterweights are very light wich limits the weight the crane can carry. Sll of these yellow boxes arent only consist of 4psc per box, so you dont even do something else than using pins. And lastly it doesnt even have a remote control. You have to use a phone app. For 700$ this is ridiculously expensive.

Considering I could buy an rc one for cheaper and make modifications to it later for little to nothing, 700 is a bit much for a lot of people especially when it comes down to determining its functional value over other important expenses.

Engineering wise it’s very well done. However the short boom length and lack of correct ballast (as per the real Liebherr crane) are disappointing. The cost here AUD $1,049.00. There is one (1) on shelf at the local Lego store, where I was yesterday to put my name down for the upcoming Concorde 👍 which is at $299 AU value for money. Cheers.

I want it, but I have no space for it built. I hardly have space for the bucket wheel excavator.

I have been waiting and saving for this kit, I'm a crane operator who runs Liebherr crawlers. Very disappointed that the Derek is show piece and not a functional super lift with ballast and that it is nothing like a actual LR13000. I will not purchase this kit

I dont think the counter weights have metal in them, because you'd have no issue lifting thing if they had metal in them. I think they're just all plastic with no space on the inside

is that 8043 motorised excavator in the opening? I have that and its not a small set. Well... I didn't think so until now!

I wish i could afford the set 😢 great review though 👍

if this one is worth 700$ why can Mouldking sell one for only 200$ which is twice as big and looks much more like the original LR 13k? you have listed several problems like poor load capacity which would be good reasons for not buying it and the only reason why u would buy that one is because its Lego?

Wow I wasn't expecting to see a Lego set tested like it was the real thing. And quite pass the test, tho.

This is basically the biggest and best ever Technic parts pack. Noice.

1:34 These round gear teeth pieces were last seen in the bucket wheel excavator of 2016

Beautiful build and more than worth the $700 price. Just because you can't afford it doesn't make it a bad set.

Meh the price still too high for me, frames everywhere just isn't a good thing, ( the blue crane that came out some years ago didnt had any, and was excellent ), the finish touch isn't there too ( many approximation were made, some sides are just panels and not really convincing, both hubs exposed... ), the functionality is reduced because of the cheap counterweight we get, the playability ( like an interchangeability of pieces for the boom amor the jibs ) isn't there, and even if the model seems great as a technic set, in my eyes it doesnt deserve more than 450€. With the recent price increase of lego, it would mean 500, but even 500 is just too much...

The thing I like most about this set is that it shows that TLG is again pushing the envelope. Which is always good to see. I am also interested in the new elements, I just might pick up one of them for that reason for MOCing purposes. However, I will be very patient with this purchase. The price is bound to drop a lot. As a set though, I have the same opinion as before, it does not look like an exciting build to me. Look, it is big, and tower cranes are fascinating. But I don't have to build this set to know that. The build itself does not look intricate or particularly pleasing. Very good review though.

This crane looks really impressive. Whoever designed this legendary Lego machine is pure genius! Best S.T.E.M. model that teaches you so many things about structures, materials, forces, stability, flexibility, levers, pulleys, mechanisms, physical pendulums, and basic mechanics, and all of which you can play with, change, and see how it behaves in real life. Amazing!! Outstanding job on the video footage and editing!

a 6ft (2m) crane mod? Man y'all temp me. I'd probably need a BUNCH more counter weights.

hehe so smol. i just spent two days building the mould king lr13000. it costs $230 usd. has 4300 pieces, and a ton of 5x7 frames. a couple hundred track links. and a ton of beams. not to mention its over 2m tall.

Legoland has just announced that the entry price is pending on the weather. Sunny day=higher entry price. Time to cancel the greedy ones.

Bro has no fear😂😂

Does the real crane move while lifting weights ? I don't think cranes like that usually don't.

dudes the only person that has the balls to drive his lego cars into water

700 is a wayyyyy too much for that.

Oh.. it's a big one! You really have a monster there 😁😁

Large crane like LR 13000 is always meant to drive on smooth ground and preferable on a wooden matts, so no off terrain driving for you mister...

How much weight can it lift?

Great review as usual. Unfortunately the problems are a deal breaker.

1:08 Do you have super powers ?

As a crane operator, this video made me laugh historically. I like it!

1:07 did you use the force there?

I could cast some concrete weights for this, ok I’m buying one then modding it!

Somebody is getting payed by Lego😂

I think this is the only Volvo set that Lego has made cuz every Volvo set got retired for some stupid reasons

I find it odd that counterweights are not secured in place by braces

Where is the part where it lifts a ton?

Personally, I much prefer the Audi Q Etron over this set. Overpriced with a bad support system. I live just outside a waterfall complex and I ABSOLUTELY COULD NOT play with it in off road
