This is a Komatsu D575A-3 ‘Super Dozer’, and it weighs 150 tons. Well, this one doesn’t, being rather smaller and slightly more plastic, but it’s still really impressive.
Built by Beat Felber of Flickr, this incredible creation shrinks the giant Komatsu down to 1:28.5 scale, yet retains much of the super dozers awesome functionality.
Powered by two SBricks, Beat’s model can be controlled and programmed via bluetooth, with adder/subtractor crawler drive allowing the model to drive and steer courtesy of an XL Motor providing forwarded propulsion and an L Motor powering the steering mechanism.
Pneumatics also feature, with air pressure built on-board by an L Motor with an automatic cut-off, and two pneumatic valves – each controlled by a Servo Motor – controlling both the lifting and tilting of the blade. Lastly lighting is taken care of via four pairs of Power Functions LEDs.
It’s a brilliantly engineered creation and you can see more – including a link to a video of the model in action – at Beat’s Komatsu D575A-3 Super Dozer album on Flickr. Take a look via the link!
