During the nine-month Great Lakes shipping season, the ore hogs—shovelers, "larry" car weighers, bulldozer operators, car pushers and "leg" men—unite in this miracle of supply that stock-piles enough iron ore to last through the winter. The leg man on a Hulett iron-ore unloader must possess a special blend of brawn, brains and a "go for broke" attitude. He must also be conscious of the safety of fellow workers below him as he deftly maneuvers a 75-ton vertical ramrod and iron-jawed grab bucket.
