This astonishing creation is an O&K RH 120 C, a 200-ton mining excavator used in British open-cast coal mines in the 1980s, and – as the most successful excavator in its class – all around the world.

Subsequently built by Terex and then Caterpillar, the RH 120 C is still in production today, with this spectacular brick-built replica paying homage to the design’s first incarnation.

Constructed by Flickr’s Beat Felber, this 1:28 scale model recreates not just the O&K’s exterior in brilliant detail, but the operation of the excavator too, thanks to a suite of Powered-Up, Control+, and Power Functions components hidden within.

A pair of Powered-Up L Motors drive the tracks, another the slewing, whilst a Power Functions XL Motor drives the huge boom. A further two motors operate the bucket, with all six able to be controlled remotely via two Control+ hubs.

Authentic period-correct decals, superb attention-to-detail, and fantastic presentation make Beat’s O&K one of the finest models to appear here this year, and you can find the full gallery of incredible imagery at his ‘O&K RH 120 C’ album on Flickr.
