TeeJay, beautiful job on the Hulett. 
My first guess on those chains would've been NorthWest Short Line - they have a Delrin chain-drive for something - maybe an O scale gearbox?
My overhead crane was intended to be one of two casthouse cranes. When I aborted that project due to lack of space and funds, I re-worked it using two outdoor cranes to which I had access as examples - one was a shorter span, while the other was considerably longer. The long one had a moveable cab, but I didn't think it necessary for this application. It did surprise me when I was checking them out just how much electrical equipment is on them that's seemingly in ordinary electrical cabinets and boxes, with no additional weather protection. The only weather which seemed to affect them was freezing rain, as they weren't always in constant use like the indoor cranes - the collector rails and pick-up shoes would get coated with ice, and it was sometimes difficult to get them moving.
