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

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...!
