[MOC] Liebherr L556 Wheel Loader | 1:21 Scale

[crazy technic]

Hi everyone,

I’m excited to share my latest project: a 1:21 scale Liebherr L556 Wheel Loader. This model was designed 100% in Stud.io with an "engineering-first" mindset. While it is currently a digital prototype, it has been built with the same structural "overkill" I use for my physical builds—utilizing heavy-duty Technic frames and reinforcements to ensure zero sag.

Technical Specifications:

• Scale: 1:21 (matches my previous Technic MOCs)

• Drivetrain: 1x XL Motor, 2-speed gearbox, and planetary wheel hubs for maximum torque.

• Functions: 4 Motors total.  

  • The XL drive motor also powers the onboard pump. (with manyal 2 speed gearbox)

  • 2 additional motors actuate the pneumatic valves for the lift and tilt functions.

  • the last motor is responsible for the steering

 

 

 

 

The Challenge:

As I am currently  finished with the design, this model is not yet real life verified. I am looking for a dedicated builder to Test this MOC.

What I provide:

• High-quality Stud.io generated instructions + .io file 

• A feature/shout-out on my YouTube channel with photos/video of your build.

• Free access to any 3 of my other MOC instructions.

What you provide:

• Hose Routing: You will need to determine the optimal pneumatic hose paths (not currently in the instructions).

• Verification: Confirming the mechanical clearances + working functions

• Media: Photos of the completed build. If you're capable of high-quality video, I’d love to feature it on my YouTube channel.

• Coding: Ideally, someone comfortable with the Powered Up environment to help refine the control logic.

 

This L556 is part of a larger 1:21 scale machinery series I’m working on. I have several other heavy-duty MOCs currently in the design phase—including scania logging truck and a container handler.

 

If you want to be the first to bring this digital design to life and have a passion for (Liebherr)  machinery, please shoot me a PM or reply below!

here is a partslist for anyone who is intrested :

Nice choice of tyres. 42209 is a brilliant set, but those tyres would have elevated it even further.

these are actualy tha audi tires, when i bought the tires + wheel hubs for another project that was what inspired me to design this

Tires are perfect for this scale and machine.

Would love to see this in brick built form and how the cables and hoses are routed :-)

They're simply built for wheel loaders. I'm hoping that one of the missing sets for this year is a Volvo hauler that uses them.

desperatly waiting for more new construction sets
