It FINALLY Happened!! – Building the Largest LEGO Technic Crane!

Today is the day. It’s finally happened…Mom, I’ve made it. I have a sponsored video with Lego. Look at the size of this thing. It only took 600 videos worth of mentions
to get it. “Just like a little Lego” “Clips like a little Lego” “Like a little Lego” “Lego style ribbon connector” “Both unsnap like little Legos” “Lego, Lego, Lego, Lego” The squeaky wheel gets the grease. I need an extra couple hands for this video. You might remember Cambry…she’s here to
help. [Cambry] Let’s get started. [Intro] So this is one of Lego’s bigger sets. This is called the Rough Terrain Crane, and
it’s one of the Lego technics, which is a slightly more complex system of Legos. You know, for people older than just children. With 4,000 pieces. We might…we might be here a while. So Cambry found what we think is the manual. [Cambry] This is the first half, and this
is the second half. [Zack] Look how thick that is. [Cambry] 79 pages of bag 1. [Zack] We’re barely through step one, but
we already have some pretty intricate designs going. And I’m not sure how this all fits together
just yet, but all of these little different parts that we’re building just snap in together
like a little Lego. Okay, let’s keep going. [Music] [Zack] Like a little Lego. So we’ve been at it for about 2 hours or so. This is the first instruction booklet and
we are this far into it. But it’s been fun! I feel like it doesn’t feel like it’s been
2 hours. [Cambry] I lost track of time. We’ve done 143 steps…144! I’m pretty proud of this. It’s big but it’s going to be like 10 times
this size so I’m excited to see what it looks like finished. [Zack] Not exactly sure where this goes in
the whole scheme of things, but it should all come together in the next couple hours. On to step number 2. There are the bags we need there. So this right here, I’m assuming is the front
portion of the crane. So we have this gear right here which turns
the steering. And the wheels will be attached on either
side here. And as the wheels are spinning, you can see
the gears inside as kind of like a differential, so if one wheel…let’s say this wheel up
here has stopped spinning, the other one can still function all by itself, and they can
work independently of each other. That’s the purpose of a differential, all
those gears in the little housing right there. Pretty sweet. [Music] [Zack] Okay, so it might not look like we’ve
accomplished much with the bags, there are still a lot more steps left. We just finished number 4, but the cool part
is we just mounted this motor and you can see the individual pistons right there inside. So as the motor turns, you can see the pistons
moving, here’s the fan in front. But you can also see where the wheels mount
right here. They are turning as the motor pumps. [Music] [Zack] Okay, so we’ve been here for about
7 hours working on this Lego project, and we’ve gotten pretty far. It doesn’t quite look like a crane yet. This is what it’s supposed to look like. This is where we’re at right now. [Cambry] It’s kind of like a huge jig saw
puzzle. And I think we’ve made it through half the
pieces, but the last couple of pieces are probably going to be the trickiest because
they are all the same color. [Zack] What’s nice though is that we have
these two massive books and they’re pretty detailed. This is the first book that we’re in, and
we haven’t gotten to that second book yet. [Cambry] Yeah, even though we’re not through
the first book, I think we’re still probably halfway there just because by the time you
get to the second book, you have less steps, less pictures because you’re adding on to
the whole structure. [Zack] So after work on this for 7 hours,
it’s definitely not like a difficult project, but it is very intricate and it keeps your
mind and your hands active the whole time, which brings me to one of my favorite quotes
that I’ve ever heard by Harrison Ford: “Anyone who stops learning is old, whether at twenty
or eighty. Anyone who keeps learning is young. The greatest thing in life is to keep your
mind young.” And I think building one of these Lego technic
projects is a way to keep your mind active and keep your mind young. The wheels feel like they’re pretty heavy
duty rubber, so it should be interesting when we see them finally on the whole contraption. [Zack] We’re making progress. So when you turn this little knob in the back,
it rotates all 4 tires at the same time. Also, fun little fact, as it’s rolling forward
and backward, you can see the pistons inside of the engine pistoning…firing! Firing is the word! [Cambry] We’re done with book number one! [Zack] Heck yeah. [Cambry] Onto number two. [Zack] So one interesting thing that translates
into real life construction equipment and traffic cones are these indicators. So if you see, when they go on a piece of
construction equipment like so, they indicate by slanting down which direction you should
walk or which direction you should drive your car to avoid the dangerous obstacles in the
middle. So it’s nice to see that Lego is translating
these real life stickers onto their project. Alright, this is day three, hour…how many
hours have we been doing this? [Cambry] I think 11. [Zack] 11 hours. And we should be able to finish today. We’re on step 10 and a half. [Cambry] Just to be clear, we’re halfway through
step 10. There’s no 10 and a half. [Zack] So on this crane there is some powered
movement and it looks like it’s all powered off with this one motor back here using a
couple different switches like this guy right here, switching, you know, to drop the legs
down or to raise the boom. And this motor connects to this battery pack
right here. If you remember those old school Lego Mindstorms,
it has the same style of connector. There are these little metal bits inside of
the Lego plug, and when it connects right here, the whole thing is powered, and you
can go forward and reverse. So it will be interesting to see how all of
the gears and contraptions inside of this Lego technic set work together when the motor
and the battery pack are working. So we’re about to install the lift cable. So it’s powered on right now, we have the
battery pack here, the motor and then this right here is a switch. So we’re going to bring that over to the side. This right here is a switch, so we’re going
to bring that back. (Small Electric Motor Sounds) And now the battery is on and we’re reeling
the line in on this spool all automatically. What’s cool is that you can see all the gears
turning inside, and I imagine if I were to switch this, it would now drop the lever out
and and unspool the spool. Pretty sweet. Is this is the part you’ve been waiting for? [Cambry] Yeah, this is the part I’ve been
waiting for because there is a whole lot of red, and I think it’s going to be more challenging
to put it all together when it’s all one color. [Zack] So we’re done with step number 10 and
we have the whole base…the whole base put up. And I think now we’re going to build the arm
for the crane itself. So still like the interior stuff, but it should
still…it should look much more like a crane when we’re done with it. So we’re 12 hours into it on step 11. [Music playing] [Zack] Cambry right now is wiring up the cable. [Cambry] Attempting to. [Zack] There’s a series of pulleys that she’s
threading it through. Alright, so three hours later we finally have
the arm of the crane done. Going all the way down. [Cambry] Okay, now lift it back up. [Zack] Instruction at it’s finest. [Cambry] All-terrain. [Zack] We are currently on step 967, and we
will be adding some exterior, some clothing, to the crane. [Music playing] [Zack] Ha ha! Its working! (Music) Now that we’ve finished one of these, I kind
of want the whole fleet of construction equipment. They do some pretty cool stuff. (Electric Motor Sounds) Alright, we are finished. How many days…how many days did that take
us? [Cambry] 17 hours. 5 days. [Zack] But it was worth it. 17 hours of entertainment. [Cambry] A week of Lego. It had 1,170 steps. [Zack] But the steps were very detailed. If this fell apart right now, I don’t think
I’d be able to reconstruct it, but with the step by step instructions, it did make it
a lot easier. If I do this again, the crane is pretty sweet
and the other construction equipment, but Lego also had a few cars. One is a Blue Bugatti which I think would
be awesome to construct. So if you do end up buying one of these Lego
technic sets, the price factors into the entertainment of building it, as well as having something
afterwards you get to play with and have like as a piece of art. It’s kind of like educational entertainment. If you’re interested in seeing what kind of
Lego technic sets Lego has to offer, I’ll put a link down in the description. Let me know in the comments which one you
think is coolest and which one you think I should do next. I’m kind of leaning towards the Bugatti. Maybe I can talk Cambry into coming over for
that one. [Cambry] It looks cool. [Zack] If you have any questions, leave them
in the comments. [Cambry] I think we deserve some like ice
cream or something. Thanks for stopping by. I’ll see you around. [Zack] Nope! Also not how we do it. [Cambry] What is it? Thanks a ton for watching. We’ll see you around.
