Onboard Bucyrus-Monighan 9w Walking Dragline

This amazing working model was built by Scentlessapprentice9, father and son. To see how good the model is, compare with the onboard video "9W Bucyrus Erie Walking Dragline Digging", posted by Scentlessapprentice9. The noisy swing gear is correct, as swing gears on the old machines had coarse teeth to accommodate loose tolerances of the swing roller path. GoPro 3+, mounted slightly above the operator's cab. This take was shot with the GoPro super wide setting, which distorts the straight lines of the boom, but gives a nice panorama. The depth of field of the GoPro is impressive, a result of sensitive modern sensors allowing a very small aperture. National Pike Show, Brownsville PA August 2014
