The truck didn't work as well as I expected, the gearbox was pretty inefficient and the highest gear was basically unusable. I didn't want to rebuild it and I thought it looked good enough, so I built a simple trailer so that the truck had something to pull, made the video and then moved on to the next project. There are dozens of really good trailers in this scale on Rebrickable, way better than I could ever build myself. So if you're looking for a good trailer, have a look over there, this project was more about the truck.

Yeah bro, I just dropped a new Lego video. This is what it’s called. IR 259G impact wrench, triple 28 foot reefer mock with rollup door and slide axle

Mit ausgefahrenem Teleskopausleger und der Wippspitze ist der Kran nur gerade so stabil genug um nicht umzufallen, dementsprechend ist die Traglast leider nahe null. Ich hab ein paar Ideen für Verbesserungen, vor allem für die Stabilität, mal schauen wann und ob ich die umsetzen kann.

Just over one bar if I remember correctly. I modified the cylinders to have less friction and more airflow, which makes it easier to run at lower pressures. With the valves modified for more airflow and lubrication, the engine can probably even run at pressures below one bar!

There are no instructions for this model. The cabin and hood are heavily based on the 9397 set

You can use Power Functions or Control+ motors, there are separate instructions for each version (links to both are in the description)

Thanks!

Thanks! It's 1:40, so pretty close to minifig scale

1:22, basierend auf dem Reifendurchmesser Er ist ein bisschen breiter als er sein sollte damit die 13er Zahnstangen für die Lenkung reinpassen. Der Ausleger ist deutlich kürzer wenn ausgefahren, sind nur 2 Teleskopierende Sektionen statt 4 und auch kürzer damit der Motor zum ausfahren reinpasst. Die längste maßstabsgetreue Wippspitze wäre 3,6 m lang!

@@stinkwellexhaustcreations Dankeschön für die schnelle und Ausführliche Antwort

Thank you!

Thank you soo much! I'm not too active on KZbin, more on Rebrickable. I enjoy building the models more than making the videos about them, but I like to be able to show how they work. So I'm mostly focusing on building the models and making instructions for them, the videos are "only" an addition. I could put more effort into them, but I'm happy with how they are and they already improved a lot since the first ones. For this particular video, I made the effort to add a lot more cuts to make it actually interesting to watch the DT-30 drive around, it's kind of slow... : )

Danke!

Cool, that'd be helpful! How do they get the steering motion from the kingpin to the axles? Do they measure the angle of the truck relative to the trailer with a sensor and then steer the axles hydraulicly? I'm planning to use a rope to transmit the rotation of the kingpin to a reel that's connected to a rack and pinion steering system. So basically when the fifth wheel rotates relative to the trailer, the string gets pulled on one side and then rotates an axle that steers the axles throughgears and gear racks.

Cool! Write me a PM over Rebrickable, I think that's the easiest way to commuinicate!

@@stinkwellexhaustcreations Please give me your email,we can communicate via email

@@stinkwellexhaustcreations Can you give me your email address so we can communicate via email?

@@stinkwellexhaustcreations Hello, I think it would be safer for us to communicate via email.

Thanks!

Yeah, it does : )

Cool!

The real one is AWD. Also it's kinda hard to make good drifts with a LEGO RWD car, and as long as you have plenty of power, AWD is a lot more fun to drive around!

What piece exactly do you mean?

The orange Gear switching things. They are rings and can thing 2 gears at once, They appeared in the Bugatti Chiron and The land rover Defender. ​@@stinkwellexhaustcreations

Lego 18947

@@thedumbasain Good idea, it actually matches the look of the real turbo setup better!

⁠​⁠@@stinkwellexhaustcreationsalso where do you get your parts from? Do you buy them individually or from sets? I’m trying to get the 64.4x 20S tyres. (32019)

Thanks! I was surprised how well it worked and how accurate it was! You can probably build your own with the pieces you have using this concept. You only need two things: measure when a certain torque is applied (in this case when the mass is lifted) and measure the rpm at that point in time. You can calculate the power with those two values

This is my creation with my building instructions. They didn't even ask me for permission to sell it.

Just over 1 kg

Do you mean that the piece that the middle gear sits on breaks off? Or does the piece of paper come loose?

Thank you!

Danke! Ich will versuchen das schild umzubauen, dass man es auch um die längsachse drehen kann. Vielleicht kommt auch noch ein kran hintendrauf, aber dazu bräuchte ich einen dritten BuWizz, sonst gehen mir die outputs aus.

Gut, das ist der dritt Account von mir 😂 ein Kran wäre sehr geil- aber ja buwizz sind arschteuer. Ich bräuchte eigentlich auch drei bekomme aber „nur“ zwei. Aber danke, du hast mir bei der Blade vorne echt geholfen mit deinem Tutorial da 🎉

@@SlaXguys Ich versuche grad noch mehr bewegungsfreiheit für das schild hinzubekommen, sollte mit kleinen pneumatikzylindern funktionieren. Der motor für die scheibenwischer steuert dann pumpe + ventil

That would be huge, I don't have nearly enough pieces for that... I tried building one in a 1:62 scale (using the boom sections from the 42042), but the turntable wasn't strong enough and the whole crane just wasn't stable enough. I will try again though and hopefully get it strong enough to actually have a usable lift capacity with a long boom.

@@stinkwellexhaustcreations if you want to build one in the 1:21 scale ill help

Thanks!

Thank you! There are links to the Rebrickable pages of the truck and the trailer in the description. There you can find the part lists and instructions! Warning: it'll be kind of expensive!

Thanks!

I think it's for easier assembling of the jib on the ground. When you connect the jib to the crane with the boom horizontally, the front part of the jib is almost at ground level which simplifies working on it a lot.

hey how many studs is your crane wide?

@@the_austrian_brick 19 studs wide at the chassis, 27 with the counterweights

With a BuWizz 2.0, that's a LEGO compatible 3rd party battery and bluetooth reciever unit that can control 4 Power Functions outputs using the BuWizz app

@@stinkwellexhaustcreationsthanks

MOC stands for "My Own Creation". Thanks!

I definitely have enough snow now. I'm working on one digitally, so stay tuned!

You're welcome! How did the competition go?

You're welcome!

That one's way slower and it only has one output per side, so not as fun : )

Cool!

I want to build more small models in the future, they're really fun!

Basically your drivetrain looks like the one in the real truck and this one is a simplified version of that to actually fit in the small size.

Thank you!

Thanks!

Thanks!

Thanks! That would be quite expensive though...

What parts are you missing? Maybe you can replace them with other parts.
