'Lego Technic 42042: Crawler Crane' Unboxing, Speed Build & Review 

This shows up in my recommended after 5 years!

This set has everything I need - blue pieces, tread links and grabber, and also it has some new building ideas implemented - I would definitely buy this.

i got to say, of all the people who review lego sets, in my own humble opinion, yours is the best. 1) Honest opinion. (very useful to consumers like me) 2) entertaining and not boring, 3) informative. 4) specially the hamster is fun to watch. though sometimes we tend to have different opinion interms of Lego Looks, but i still enjoy your review, gives me more insight on Lego official sets. keep it up, i hope to see more Old and new Lego Technic Sets.

Just recently bought this set, 2 years after initial release. It's better that I expected (and I really liked it before I got it). I did not have any issues with lifting a 0,5 kg bottle. I use regular AA batteries, not the rechargable ones. Did not observe any clutch slipping. Make sure the roller wwheels on the grabber are free to move - they will create friction if under load and without ability to spin. The only disadvantage I can see is that the model is not able to turn itself using treads - this would be awesome.

I really like the selectable gears on these models. They are a lot of fun to build and you learn a lot about gearing systems. The excavator with the grabber has a similar system with one motor driving 3 functions (2 boom, 1 grabber), but forward/reverse is controlled by the battery switch, not the gearing itself. That is part of what makes this set more interesting. Also really like the blue elements. I just finished the volvo front loader and missed building the intricate gearboxes.

I purchased this set today and put it together this evening, and man what a rush of nostalgia it was using Lego again. I found your videos and really loved some of the stuff that you did with your creations, and it inspired me to pick it back up after 7 years hiatus. I rarely worked with Technic sets, nonetheless ones of this caliber, when I was younger, making this an interesting experience and a bit of a challenge.

I added the metal hook from a 1980's power crane to mine and put longer technic thread on the main winch. i like how another battery box can be clicked on to add some extra counter weight.

This was uploaded on my birthday. Thanks for the gift Sariel! Love it

Thanks a lot sariel you are the best lego technik guy!!!

THIS IS MY 2nd FAVOURITE LEGO TECHNIC CRANE

Love this set!

Wreszcie jest! Dzięki za review ;) like

That Review whas great and i am going to buy it today after i saw how nice this set is. Thank you for your work

You were right, that damned clutch gear on the winch almost ruins the whole point of the crane, as it barely lifts anything... I was considering changing the hull somehow to allow for a manual cog to be turned to overcome this, but realized that would be pointless after test-fitting the clutch onto a 42032 Compact Loader. Even with no load in the bucket, the clutch gear slips constantly and any hand turning short of delicate surgeon-hands renders the function useless (I guess hands just have some kind of unholy torque or something...). In the end, I kept the clutch gear only on the input shaft of the driving function and replaced the other one with the Z24 gear out of the Loader. Even with the standard gearing on the winch it seems able to lift most reasonably scaled loads (I tested it on a 31037 Creator jeep set and a 60027 City Camper, along with the Compact Loader that "donated" the replacement gear, the mini Rescue Helicopter from a couple of years ago and one of the older City sea-planes, which I ended up leaving in the grabber just because it seemed amusing). The heaviest thing I lifted with a clear conscience was the 42037 buggy, but the problem is the back of the crane weighs less than this, so unless you hold it down the winch doesn't actually lift the load, it just pulls the boom down on top of it and topples over. If held down though, it slowly lifts it off the ground with no grinding or fuss. I guess the only way to improve that is extend the back of the crane with more structure to make it heavier so it can remain stable under lifting. Only downside to swapping the clutch out seems to be that you have to be careful with the winch now, as instead of stopping when it reels all the way in, the motor keeps pulling on it and tries to pull the boom in until it grinds to a halt, possibly damaging it. Having a bit of responsibility is welcomed, though, if you're pretending to be a crane operator :). In any case, thank you again for your wonderful reviews and hard work in making the build videos, and have a very nice week-end!

This definitely reminds me of the older 8043 Motorized Excavator set.

The best channel!

I know a way to separate the two turntable pieces: grab a brick remover, use the pryer-type thing on the end and put it between the two pieces, twist the brick remover, then use your finger to finish prying them apart, and then they are separated. (I figured out how to do that in robotics)

gee, I've been here for 7 years and counting... Things have changed so much.

Awesome review! I hope we continue to get more blue sets until it is no longer a rare color.

That looks awesome

For the steering, surely a simple solution would be to have a differential instead of those beveled gears that go straight to the drivewheels, and have some sort of manually operated tipping bar that could brake against the left and right driveshaft? It'd probably have to be controlled from the chassis rather than the superstructure though.

ITS OVER 9000 !!!!!!!!!!!!!!!!!!!!

17:36 I thought it was the sound of the gears skipping :))

it looks very cool and it is

Really good making

when trying to elevate the crane/boom from a full declination, the clutch slips for sometime, then when it gains some cable/thread, it goes up normally...anyone facing this issue ?

I can't decide between this set and the mobile crane mk ii, on one hand i've always wanted the mobile crane and it has been a dream of mine to own, but I think this one may be a better build and have more play value?

Good time lapse

Now I'll be still be greateful if you build the B-Modell

its interesting how you didnt like the battery box, but to me the grey made me think of the big concrete blocks they put on the back of cranes.

Can you keep the LEGO-sets or do you need to send them back?

Very nice review! Is this gearbox really more complex than in 8043 set?!

What do you think can be modified with this set to carry all of the Hammonds you have? And even with a 1-meter boom? Also, suspension. Is it possible? You should do more outtake clips. And I think it's a good thing the drive is slow. You wouldn't want any of your hamsters to use 'em, especially if they get a hold of a wrecking ball.

thanks

20:50 When you have unlimited lego pieces :

Now I'm hungry for bananas.

Hey, the pneumatics on my 42008 service truck aren't working for some reason. The pump works fine but none of the pistons seem to move at all! Did i do something wrong? Is my set broken? Has one of the pneumatic pipes broken?

do u have any close up pictures of the gearbox? im still very curious on how it works especially since the red gears seem connected all to one another and not separated

Intresting

Thanks, have you seen the video of the new 2nd half sets? I cant believe they are already here!

my dream set gotta get it soon before it inflates too much

it isn't true that full remote control of this model is extremely difficult. it's quite easy :) only 3 ir receiver and additional 5 motors needed

Are you saying this gearbox is more complex than in 42009 crane's super-structure! Mind-boggling

IS THE MOUSE INCLUDED

Ktoś wie gdzie dorwę jeszcze ten zestaw w rozsądnej cenie ?

Sariel I love you videos, always have, when trying to lift objects, if you raises the winch all the way up, then lowered the boom to grab the object, do you have more lifting strength? And when moving the boom, is the grapple offset by the movement of the boom, other then the obvious up and down motion. Like when extending the 42009 arm, the winch would move up. Thank you for all your hard work

if you dont have batteries, are you still able to manually use the functions?

Now that you've reviewed all 2015 Technic sets, which out of all 2015 sets stand out the most, in terms of looks, value, or pieces?

Does removing clutch gear and add more counterweight will increase the lifting capacity?

Am late, but wanted to say there are a total of 4 possible combinations of the functions.

Mam pytanko, ile trzeba by wydac i jaki kupic zestaw by zaczac zabawe z pneumatyka i silnikami lego? jako dziecko bardzo duzo bawilem sie lego, ale z biegiem lat te zestawy i klocki mi poginely itp, chetnie do tego wroce ale nie wiem od czego zaczac, interesuja mnie te pneumatyczne i elektryczne wynalazki lego.

Is there enough room to replace the motor for stronger one? Together with gearing it a bit it could be pretty good seems like.

Do you get the models directly from LEGO to make a review, or "unofficial" from another source?

Hi Sariel. Which would you recommend... This 42042 set or 42043 for a somewhat new collector? The pneumatic pieces are tempting but at quite an expense. My girls love watching your videos with me, especially when the hamsters arrives. They enjoy making the occasional set with me and it helps them to learn about axles, gears etc... Keep up the great work!!

How long will this run if it is turn on all the time? And this or 42039

Got one from the wife for Christmas.

When the Boom is shorter will the Claw go lower?

Dude, how did you finish that monstrosity in only three hours? It took me six!

I have this Crane

the grabber on that particular crane is sort of ment for digging

dat "wasted" though haha :D

In you video you say it will be hard to motorize and I agree , but we could do what dokludi did in his recreation of the moc. Disclaimer : I have not linked the video because I don't know how you would fee about other people getting views from your video cause I linked it.

Да...Интересно, сколько он может стоить?

think you should try make it better ie full rc control like your tanks and make it lift better :)

Do the b model pls

love the memes XD

Sariel Hello! Can you tell me, what is better. 42042 or 42052?

Plz tell me the names off the song (s) you use in your video

Until the B instructions will be available, why not "fix" this set? :)

And B model please.

is there much difference between a L motor and a M motor?

Which would you prefer the crawler crane or the heavy lift helicopter?

This or 42054?

I hope this model is more stable than Meccano crawler crane.

what do you mean no suspension? how about those boogies?

The stopped to make front open boxes? D:

So is that mean lego also provided instruction on how to make an RC version

I feel with the pieces here, the B-model could easily been some sort of blue shipping-container crane, like those at the docks in GTA V.

what did you do with the bananas after?

Do you like 42009 more or this more?

do they already know something about the 2016 models?

Which would you recommend this or the mkII crane

Sariel, will you be reviewing this year's small Lego sets too?

i love this set but it is so costly

A new audio track for your vids is much needed.

About how long is the boom

is this set more complex than the 8258 set?

Dat B model doe.

Sariel? Please place the model B of lego 42042

captain?

More than 2000PLN for that thing, I don't believe how the prices are going high...

Don't say to me that when you were cutting the bananas when this set was delivered.

this and the arocs or the mobile crane mk2

remember that old motorized excavator set? THAT was complex

Where do you get those horse mask?

Do u think you could make this rc

aren't they going to make smaller sets for 2H2015?

jaka cena tego cuda? kupie to chocbym musial wziąć kredyt..

Now he is probably thinking of a mod for it

Legos clutch gear is crap because even if the motor has enough power, the clutch gear stops the motors power. I know it was made to protect the motor but if used responsibly, u dont need it i just replace it with a normal gear by standard
