SIZE MATTERS!
I am really enjoying all these threads about the "classic" Hobart dishmachines.
I am old, but not that old that I would have worked on the XM's and CM' b ut have worked on everything since at one time or another. The oldest AM I worked on was probably an AM-7 way back but here in Central Florida, mostr of the original C-lines have been replaced by the C-line A series and now the CLe series. Same goes for the Flight machines. Even the FT-800's are a fading breed and only the very largest facilities have Flight machines anyway. Most work fine with some combination of rack conveyor machines whether made by Hobart or Champion or even Mieko.( Don't cringe, Eddie!)
The longest flight machine I ever saw was at the former United Airlines Terminal Kitchen at JFK Airport. It was a FT-331 which meant it was 31 feet long! It was a standard 5-8-5 machine with a 13 foot unloading section. The length, just like the Clines is determined by the size of the sections that make up the machine.
In the case of the United machine, it had a 5ft load section, an 8ft center section and a 5ft rinse section and then the unload of 13ft.
C-line machines are modeled after the length of the machine sections such as a C44 was 44" long C54 was 54 inches (both were single tanks). C64 and C81 were dual tanks and the prewash sections were either 22 inches or 36 inches.
Most manufacturers use those standard dimensions and when you add the inches up it gives you the total length of the machine.
The example on ebay is a CRS-103, this is an 81 inch wash/rinse 2 tank plus a 22 inch prewash.
And btw, I would have to say that any flight machine by any manufacturer will far exceed the capacity of a human being to load and unload it at its maximimum capacity. They just wash way too many dishes than you can load and unload without having the machine stop at some point. The loader can't get enough dishes in his or her hands to fully load it and the unloader has to stack them somewhere when they come out. I think the loader has it easier.
