South of Main Street, another contractor, John T. Fanning Company, used this two-tower configuration for channel excavation. The operation is similar to a dragline, but employs two buckets operated separately from each tower, thus allowing excavation from both sides simultaneously. In this December 22, 1908, view, one bucket is being dumped behind the right tower and the other is being loaded in the cut. (MWRD photo 3977)
