Build and explore this remarkable LEGO® Technic™ reproduction of one of the world’s most impressive hydraulic excavators, the Liebherr R 9800. Developed in partnership with Liebherr, this replica model is controlled via the LEGO TECHNIC CONTROL+ app and comes with an array of advanced app-controlled features and functions that put you in complete control.

Choose from 4 different screens with cool graphics that add to the super-realistic play experience. Drive forward, reverse, steer via individual track control, rotate the superstructure, extend, raise and lower the boom, and open and tilt the bucket at the touch of a fingertip. Select an on-screen drag pattern for the boom and see it respond to your command.

Use pre-set commands or record the excavator's actions to create complex sequences of movements, then turn up the authenticity with real Liebherr R 9800 sound effects—all from the comfort of your smart device!

And when you're ready, you can test out your skills in the app's challenges and achievement section—how many reward badges can you collect? This high-fidelity replica is packed with true-to-life, brick-built details, such as hydraulic tubing and pumps, cooling vents, a fire extinguisher system and a detailed operator’s cab with seat, joystick and control panel. A classic colour scheme with intricate sticker detailing adds the finishing touch to this magnificent LEGO construction toy for kids and grown-ups.

Lego technic

Bought from iwoot many off times. Will always come back to here for my Lego. Good service and always top quality products.

Massive build... great fun

I have been looking at this for ages and the price drop on site just made it irresistible. It's a massive build I have only just started but already looks like it is going to be a great item not only to display but also use via the controller app. Ordering and delivery was easy and quick - absolutely no issues using IWOOT again and again.

Super Sized Lego

Wow what a kit! The size of the model, the motors and the detailing at all fantastic. Easily the best model yet. And the price was a huge discount on retail price that originally held me back from the purchase. The Sian is a beautiful model, but the Liebherr blows it out the park for size and functionality

Bigger Digger!

Many pieces and very detailed. It's got to be one of the best Technic models ever.


Just bought it for my husband, he absolutely loves it! Awesome "toy". Quick, trackable delivery. Thank you

Good one this...

Great technical model to build and then use the Lego App to control. My 12 year old son enjoyed building this with help and advice from his old dad every once in a while....

Lego excavator

Bought this Saturday my first purchase from iwoot had it delivered Sunday, took a day and half to build it and love it vary good build


I have bought most of the lego on this site for my husband in lockdown but as a self proclaimed expert I will say this took him 2 and a half days, the control's are easy from your phone but I would say you need good quality batteries other than that it's great!!

Good service and product

This is my 2nd lego set bought from IWOOT. It came in with good conditions and I am really pleased with it

Incredible build and play experience

This build was fun and the end result is really amazing. The build is pretty straight forward. Setting up of Power up hubs and motors with smart is easy too. Once setup the the control + app is very easy to use too. The overall play experience is amazing as it is as if you are operating an excavator in real life. This one is must have for any Technic fans! Highly recommended.
