Hi, and welcome to the Lego technic Designer workshop today. I'm going to show you the biggest technic model
We ever developed and with me today. I also have marcus the designer of the Bucket-wheel excavator
So Marcus tell me
Why is it so big?
Hello reason in real lives are also quite big because it's it's about physics
You know you have to scoop something up from here and put it on a conveyor belt
Through the machine drop it down on the other conveyor belt and get all the machine again, so it it's about physics
You know because it has to go up and fall down and go out [again]
So this is why it's so big and you say in real life
It's also really big you actually you're from germany yes, and you actually grew up in an area where they have these machines
How do you remember that exactly when I was a little kid there was always a happening when they tried to move them from one?
Gravel pit to the other one so that it's a big happening a lot of 10,000 people [aren't] watching these and they're actually
over 200 [metres] [long] and almost 80 90 [Metres] high and
It's a spectacular to see them. It's really amazing
What do you use a machine like this for?
It's a form mining in the soft soil, so everything which is soft I can scoop up with with the buckets and then
Put it on a big actually they have a big system of conveyor belts
and they can use a lot of soil from one place to another so
What was the biggest [challenge] with this machine?
I think the biggest challenging is actually balancing machine because it's so big you know like it
you have a very heavy part in the front and
Then you have to counter this and this why the machines build up like this the whole arm swings
onto
The Turntables here so and then you have the battery box and the motor in the back as a counterweight
So that's the machine is in balance [this] actually was the biggest problem with all the machine to actually have the balance
So this machine also comes with [build] [and] power function which actually makes it run and pick, but they're also extra stuff
Exactly to actually to have a nice experience doing it we [edits] [a] few bricks
So you can actually instantly start playing with it
And you get a truck where you can actually take these breaks and through the [machine] and pull it the truck up that
Actually runs index for real it runs the big story. Oh, yeah quite a while to actually make it to it
so you [could] actually show me how it works because I brought something extra because I
Actually built myself a mine, and I just wondered if you could show me how it works
Of course and first of all we have to start the motor
like here, and now nothing is happening because you can choose on the function, so I start the
Bucket wheel at the end of the
Other conveyor belt I put my small truck. So actually the stuff falls into the truck like this and
Then I start lowering
the Bucket Wheel into the soil and house testing
and
Then you can see it actually starts then after a while the first bricks start falling into the machine here
And they wore up here the conveyor belt [pull] on the small slats there and then on this conveyor belt
and
Then [they] actually can start turning the [machines] so like in the real life is actually a start turning machine in here
and then there's also picked the other soil and
then I put the
thing here that is actually synchronized, so it's a key space with machine here and
when you turn the machine
The Bricks will go still fall into the truck here
I have to stop it now before we run into the all mine here, but it's how it works
Now you're done. We're sitting there. [I] [just]
Raise the
Arm a little bit and you have one to go in new position
Then you can go in in position drive is the drive position and you want to go
Backwards then go like this, and then she will drive away from the dignified. There is ready for a new place today exactly
So this machine you can rebuild this machine into an alternative model. Yes, and that is this one
The mobile aggregate processing plant what does that actually do it's actually it's kind of a sorting machine
Yeah, actually you can fill your breaks in here
you can see you have two kinds of bricks you have the large one and the small ones and
this is actually shorting this work, so if I take these bricks
into the scoop here like this and
then start the machine which a little here like this and
You can see while sorting it then the small bricks will fall out here and the big bricks will come out here
So it's a quite clever mechanism. We did there actually for sorting it out
Now that we sorted that out
you can actually go and buy your own pocket [Waleska] vader and if you wish to you can rebuild it into this sewing machine [to]
Amazing machines so until next time happy building and take care
you
