DLuders Posted February 10, 2011 Posted February 10, 2011 On his Brickshelf gallery, Drakolder / mosmaat posted 75 BIG pictures of his interesting Lego Technic Linetrac 830G combination bulldozer/crane. The real Linetrac machine is used to carry utility poles up steep mountainsides and set them into the earth. It uses four Lego Power Functions IR Remote Control units. His shows him operating the bulldozer's treads plus the folding crane arm. Two Linear Actuators extend the rotating arm, and knobs extend the jib and two pneumatic stabilizers. The shows "4 Rigs in One. Revolutionary design this vehicle constructs roads, digs holes, lifts lines, sets poles and has a man basket with a working height of 80 feet. Its compact design and low ground pressure provide a cost-effective and environmentally-friendly alternative to traditional utility line construction equipment." Quote
