[MOC] Goldhofer AST-1X 1360

[Uranox]

Today, I would like to share my first creation on Eurobricks with you all. A model of a giant towbarless Pushback Tug. To be exact, the Goldhofer AST-1X 1360.

The real vehicle can lift up the front landing gear of the biggest aircrafts.

I tryed to build all the functions, how they are build in the real Goldhofer, especially with the rear steering.

The model has 8 RC functions:
- Front wheel drive (XL Motor)
- Front wheel steering (M Motor)
- Rear wheel steering (2x M Motor) -- I had to decide, whether I would like to have crab steering or steering with different wheel angles to allow smooth driving. In the end I've chosen the second option, because crab steering is still kind of possible.
- Raise cabin (M Motor)
- Pneumatic pump (L Motor)
- Raise landing gear (L Motor)
- Close lid (M Motor)
- Fix landing gear (M Motor)

Unfortunately, the model has some flaws. The cabin is lifted in a weird way, because of the battery box under it and I struggled with the lifting section. I had to use really strong clutch gears and worn out valves, and even with that, the valves didn't switch always. Also I had a problem with one of the pneumatic cylinders, the reason why I used two pumps. As a result I had to glue two 2L axle between the pumps to the red 1x2 thin liftarms because of the vibration. I was sick of searching for another solution .

Here is a quick render, made with LDD and Bluerender.

I already took the model apart, but l would still love to hear your opinion, some tips or criticism. Maybe I'll give that model another go in the future.

It looks awsome! The pictures are good, and it looks to work ok.

Good model for first entry here.

Wellcome to Eurobricks 

By my calculations this is some 1:22 model? Real AST 1X has 17.5-25 tires (1375mm in diameter)

Despite the several mechanical flaws of this model, it is well done and looks stunning. Great job!

I had no firm scale, but you are correct, that it is about 1:22. Even if it is one stud too long.

Thanks for your comments.

Welcome to EuroBricks!

Wow, this is a really nice build! Even if it doesn't work perfectly, the inclusion of all the major functions is great!

Sorry, I missed that. The stickers are very good also.

Very interesting model!

Am I missing something here?

I mean, these are not the same models.... but we just had the EXACT same model posted earlier this week by a different user:

 

And the music in the youtube videos is even the same.  I mean, the models are different, several similarities but definitely different.  How is this possible?  Was there some collaboration on the projects?  Don't get me wrong, I think both are great but the probabilities for both exact same models (which we never even see anyways) in the same week with the same music in the videos is just too weird.....

I'm glad I'm not the only one thinking wtf

This is pure coincidence

I saw @Uranox video on Youtube only few hours after posting mine on youtube/eurobrick. We just had the same idée in the same time.

In fact this is not the first time it happen. My previous MOC was a catering truck, posted on Youtube on July 5th, few days later @BrickbyBrickTechnic was releasing his own

Now I'm pretty curious, will my next have a doppelgänger too? (it will probably be not another airport vehicule)

This was actually all pure coincidence, how Superkoala said, also the music in the video. I couldn't believe it myself at first . So there was no collaboration.

I started designing my model in late 2015 and had it finished for quite some time.

I guess, I should have mentioned that.

I did not intend to "doppelgang" your MOC- our catering trucks are quite different.

Realistic model turned out!

Agree.

By the way, those are are really specific vehicle, and quite rare in lego (technic) so it's good to see other variant from other builder.

IMHO it is apsolutely OK that each model have each own topic. Both models are nice
