A utility mech with a long extendable crane arm. Used for positioning of heavy cargo in difficult to maneuver places. Based off of Mark Stafford's excellent mecha design published in The Lego Adventure Book. See some of his variants back from 2012 here: www.flickr.com/photos/nabii/8183029427/in/dateposted/ Took me 8 years to build one but thanks for the instructions, Mark!
