Liebherr R 944 C Tunneling Excavator
Fully functional model of tunneling excavator.
About this creation
I always wanted to build a fully functional excavator. But when I started to look after some inspiration, I realized that there many typical crawler excavators built from Lego bricks.

Then I started looking for something less exploited. I found a special version of Liebherr R 944 C, used to dig (or rather, scrape) tunnels.
This special version has arm tilting mechanism, which is quite unique among crawler excavators. That's what determined the selection of a model for mapping. And then I started to have problems .... and I'm not talking at all about mechanic problems.

So far, every machine that I had tried to build had quite a lot of images available online. Unfortunately, this is a new Liebherr machine, so its pictures are quite hard to find. (I've found 8, half of which don't show too many details)

This model was built thanks to cranesetc.com, which has a lot of great reviews of metal models. Including Liebherr R 944 C :)

General view:




There are nine motors used in total, three are located in the chassis, three in the superstructure and three in uppper parts of the arm:



Chassis mechanisms:



Two XL motors drive the tracks, single M motor raise and lower the dozer blade.

Superstructure mechanisms:

The superstructure is rotated by single 47154c01 motor.

The arm is raised and lowered by two Linear Actuators driven by single XL motor:





The upper part of the arm is rotated by single M motor:




The jib is raised and lowered by single linear actuator driven by single XL motor:




The milling head is tilted by single M motor:




And a movie:


Thanks for watching :)

High quality stuff you've got here, Chief! Like upscale Tonka. The Lego Home Office needs to study these!

Marek, this is truly impressive. You are the king of Power Functions. It amazes me that it looks so realistic with all of the use of Technic parts and motors. It has the feel of something that weighs tons, not a couple of kilos. Regards, Eric.

nice! The only thing i would say is use the slightly bigger sawblades... but still good job!

Very good model. I have seen this machine before, and looks just like the german diecast model they have out there. Im sure it must have been more complicated than regular machine. Proper job

OMG that is so cool. it must have taken so long to do. getting all the motors in the right spot and building it. also figuring out how to do all that movement. but u were making me worry untill the end about the tracks actually working. but that is so cool. only one problem, i want to see it dig something like a pile of legos or some loose dirt or sand.

This is a perfect remake! The shape, the color and the functions(especially) are all very accurate!

Unbelievable!!! So many functions in such a confined space is simply unbelievable! Now put a cam on it, increase the IR range and you will have the best toy to plunder Fort Knox... hehehe! Best wishes, Jens
