Lego walking dragline

Video taken of me operating my 1:44 scale Lego model of a Marion 8900 walking dragline. The model is still not finished, has 24,000 pieces, weighs 80 lbs so far, and runs on 30 Lego 9v motors powered by 3 voltage regulators. There was no glue used in the model. (You can tell because the left shoe has actually come off the model in this video, oops) The actual machine was built in 1967 and was the largest dragline at the time. Its operating weight was 14 million pounds, it had a 250’ long boom, and dug with a 155 cubic yard bucket.
