It’s been a summery weekend here at TLCB, and this writer has been enjoying the great outdoors. Spare a thought then for those working far away from the sun, bringing us the materials out of the ground that we use in everyday life. However, one upside to such a job is that someone gets to drive machines like this one; the huge mining excavators.

This one isn’t huge at all though, having been thoroughly miniaturised by builder Krall, yet it’s still packed with Technic functionality. A rotating superstructure, rolling tracks, a two-stage motorised arm and a motorised bucket all feature, and there’s more to see of Krall’s creation at his Flickr photostream and at the Eurobricks discussion forum.
