In this video we'll see the
culmination of all of our work and see this thing stand
tall for the very first time Two years... Wow, okay, what's happened? The first time this project was
announced and I heard about it was actually the first time I met
James at the GTA expo in 2016 "We're even planning on doing a
power loader from the aliens movie" "Hey guys hope you enjoyed the expo
I'm here with one of my fans who's been with the channel since the original
Elysium lift, this is Bogdan" Shortly after I ended up
working at Hacksmith industries A few years had gone by until I brought the
project up to James and asked if the alien's power loader was still something
he'd be interested in making real He said he was so we started this
project over christmas break in 2018 By that summer we had one fully working
arm but I had to put the project on hold to train and compete for mechatronics
world skills in Kazan, Russia While I was away, James found
this amazing facility and the team had started the tedious process of moving in After getting settled in we completed
our first large-scale project here: The half-scale cyber truck And with this success we decided
to bring back the power loader but just as we started to ramp things up again The pandemic hit No team, no budget, no power loader Well, we survived the pandemic and decided
to continue this project this past fall after James managed to secure
a partnership with caterpillar The official manufacturer
of the power loader in 2100 With the 239D skid steer as the
base and power unit for our project It seemed like we were finally within arm's reach
of completing this project and in this video we'll see the culmination of all of our work and see
this thing stand tall for the very first time But first we're going to have
to get this thing painted But wait- wasn't this thing yellow a year ago? It was and we were so excited that we rushed
into painting and did a pretty poor job, we didn't even use a consistent painting method Some parts were glossy rolled on paint but other
parts were a dull spray paint, it was a mess This is a big project for our
channel so let's do it right Caterpillar gave us buckets of
the official caterpillar yellow so let's head out and get this thing
painted at Engineered Lifting Systems We're here at engineered lifting systems
and they have this giant paint booth and we're going to paint the power loader Now, this company makes all
kinds of awesome products From overhead cranes to material handling
conveyor belts and everything in between In fact, the way we met them is because
they're actually fans of the channel and they donated a crane to us called an easy
arm you'll see that later in the video When I came for a tour of this facility I noticed
they had the giant paint booth and I had to ask Can we paint the power loader here?
Because we really can't do that at our shop because we don't have a paint
booth and it's really big to paint They said yes, so we're gonna get started Okay first coat complete time for lap two All right guys the painting is
done and it looks phenomenal, Chris you did an amazing job, really really nice Which means this week it's time
to put the entire thing together Chris and Dave you guys are with me we're gonna try to put everything onto the cat
and get the whole thing assembled And Tyler I'm gonna get you
working on the roll cage Sounds good? All right let's get to it First up we're going to install
the legs so what we're going to do is we're going to bring the fork over, get some straps through the holes, I'm going to lift the legs up and over top the cat I'm going to set it down slowly and
put some bolts to hold it in place Sounds good? Dave you want to get the forklift?
Chris you want to get the lifting straps? keep going keep going... Okay we're good that's in there So now we've got 16 of these bolts to put in
that is going to secure the legs to the cat and that should make it really really rigid
and should be able to hold the full weight of the maximum load for the power loader Let's get started screwing these in We had some difficulty getting the legs
in the first time because one of the hoses was kind of interfering so we've readjusted
the hydraulic hose and everything fits now We've got all the bolts in we just have to
tighten them and we can move on to the chest So I'm going to be making the roll
cage, this is what I'm going to be using and I'm going to be cutting,
grinding and welding it all together Let's get started The next piece is gonna be the
chest so we're gonna have to do is: We're gonna have to put the bushings into
the legs get them all greased up and ready Then we're going to pick this up the
exact same way we did with the legs We'll use the straps, pick it up with a
forklift, bring it over slowly, lower it down and another person is going to need to take
the bushing tube and slide it through all both of the legs and all the bushings Hopefully once that's done,
the chest will be secured We can put the bolts in and then
the chest will be fully attached We have the upper body fully mounted now
but as you can tell it can actually still rock forward and back, which is going to make
it really difficult for us to put the arms on In order to solve that, what we're going
to do is we're going to install the rear hydraulics which will hold the upper
body straight while we put on the arms Let's get to it Oh that's nice, perfect! So now the last step is just
make sure it's all the way back Okay so the rear hydraulic cylinders are in which means this thing should no
longer move forward and back That means it's time to start doing the arms First things first is going
to be the rear back muscles Slash deltoid plates, let's do those first This power loader is getting
so close to completion It's a ton of work I need some time to unwind And what better way than to engage in
massive tank battles with a global community World of Tanks is free to play and
with over 550 tanks and 40 different battle arenas to choose from the
action is different every time If you are as picky about the details as
I am, you're gonna love world of tanks It's historically accurate, the
tanks are authentic models and feature characteristics that will
make you feel like a real general Take your tank across open fields
climb steep hills sneak through forests tear across deserts and pick
your battles in urban industrial zones If you're a new player and register on
the wargaming portal using my link below you're going to get 250 000 credits
and 7 days of premium access Plus if you sign up using my link below world
of tanks will get you off on the right foot... Or tread By giving you three rental
tanks for 10 battles each I'll see you on the battlefield These are the next pieces we're putting in
and these are what I call the deltoid plates These are actually the back muscles
that allow the entire arm to lift and these have to be very strong because they're
actually have a very large mechanical disadvantage The cylinder is really close to the arm so
it needs to be able to hold a lot of force They're made out of air 400 plate
steel, really strong but really heavy so hopefully this goes well We've only done this be once before and
this thing was a lot lower to the ground so we'll give it a try There you go you just kind
of want to go adding this Grease makes it way way easier for us to get
the tubes in and to get everything aligned but also the grease will actually prevent
the steel that isn't painted from rusting so that's gonna make this thing last a lot longer Okay so the deltoid plates are all
on we have to basically fit them into the shoulder and then drop in the giant pin We got that bolted in so now these things
are fully secured and they move really well which means the next step is the arm So I think what we're going to do next is actually
hook up the electrical system again, drop it back a few feet, that way we have the assistance
of the crane to move the arms into place Let's do that now All right so next up we're doing the biceps and these holes right here are actually
going to go on to the deltoid plates We're going to basically pick these up, they're
going to slide onto those big bushing tubes and there's an end cap that screws on with
one giant bolt to hold the entire arm on But before we do that we have to
put the linkage plates on first and that's what's gonna allow the deltoid
cylinder to control and lift the entire arm All right there's one over here If both of us can grab one This is all ready We're gonna pick it up with a crane and
hopefully be able to slide it onto the shoulder Okay we got it Watch the bushing That's two arms or two biceps Okay so the bicep is all the way on now As you can see you can swing freely
and it has nowhere else to go which is we got the pan and the bicep Now, next up, the forearm The forearm is up next but before we put
that on in order to make our life simpler we are actually going to attach it to
the wrist first so we're going to put the wrist onto the forearm and then
get the forearm up onto the bicep Got an arm now We got this entire arm fully assembled now but
we're not going to start the other one because we're actually waiting for a few more bushings so
while we wait for that we're going to put in some of the hydraulics because the arm is just swinging
around right now as we're trying to put pieces on So now this part is going to be locked
so when we do the front or the hand it won't try to swing back and forth We have to do the same with the bicep
as well as the deltoid and the shoulder We got it, okay so next we
can install the shoulder hydraulics which are going to go inside the body We've got to pull those pins out, get them
nice and aligned and then hopefully drop the pins through and I'll hold the shoulder still
while we're installing the rest of the arms This is how you use a hammer right Chris? Last cylinder for this side Here we go oh my god We ended up lifting the arms into place with
our forklift and putting the bushings in, getting them screwed in so the arms are
fully attached to the upper body now Then we installed the hydraulics to make sure
that nothing moves while we install the arms So next up is going to be the hands
and to do that we're going to install the bearings and then the palms
are going to go onto the bearings These bearings are actually called cross roller
bearing- Hey google shut up for like three minutes No don't get louder!! These are called cross roller bearings and
these are used for industrial applications where you need a lot of force and easy
mounting while being very low profile For example our power loader palm these
can actually hold a lot of weight in every direction and are supposed to
be super reliable and super robust Let's see if they hold up to
our application, fingers crossed We'll install the hydraulic motor fixture, get the entire palm in place and that allows us
to put the cylinders and the fingers in And hopefully we'll have a fully working hand So all the pieces have been cut
and beveled so let's start welding The finger attachment mechanism
is actually really complicated but it works so we're gonna stick with it basically
you have this linkage piece that has to go on the cylinder first, into the hand and then the
finger will slide into the back just like so But first we're gonna do the motor Grippers are up next which
is actually the harder part Okay almost ready for fingies So we're gonna put the hoses on first, then get into the gripper so that when we
get around to wiring up all the hydraulics the hoses are already there and we don't
have to pull the hydraulics back out Man this is awesome Hey Bogdan are you sure you use the
right scale model of me in solidworks? The roll cage seems a bit small... Okay so getting it upright
was actually the easy part but we might have to make some
adjustments to the roll cage In the next episode of the aliens power
loader series we're gonna dive deep into the control system which may possibly
be the hardest part of the entire build so it might be a little while
before that video comes out But in it, this sleeping giant
will finally come to life...!
