Does anyone know what kind of ladder this is? It's a 1970 Seagrave Pumper for sale in Jackson, Minnesota. I'm trying to figure out its history and specs. Any info would be appreciated!

Former Chicago FD ladder truck for sale E-179?
Looking at the photos, it seems like it might be an old Seagrave aerial ladder truck that was once used by the Chicago Fire Department. The model number E-179 is mentioned in the captions, but I’m not sure if that’s accurate or just a guess. If anyone has any experience with these types of trucks or knows more about their history, I’d love to hear from you. Thanks in advance for any help!
Vacuum rake dryer is mainly used for drying explosive, easily oxidized and paste materials. Under vacuum conditions, the boiling point of the solvent is reduced, and the air is isolated, so it avoids oxidation, overheating and deterioration of material during the drying process. The heating medium (hot water, heat transfer oil or steam) is introduced into the jacket. A certain amount of wet materials are added into the drying chamber. The rake shaft stirs the materials to heat them evenly. After the materials meet the drying requirements, open the discharge valve at the lower part of the drying chamber to allow the materials to move to the middle under the stirring of the rake shaft for discharging.
