I haven't got a clue, but when I saw it my first thought was military. It looks like it was designed by a goverment committie.

That was my first thoughts as well.
There is a comedy movie about the making of the Bradley fighting vehicle that is quite humorous and that is what comes to mind when looking at this contraption.95zIV

That one looks pretty much the same as this one.

Serial numbers are very close as well. Nice find 95zIV!

Perhaps it was used to load torpedos into submarines in places where no crane was available?

My take on that proposal is that the boom does not have the needed reach. Running the thing on a pier is not going to work either.
Some suggested a pipe layer. Decent call . . . but, no counter weight.
Another suggested a yard crane. Now this bears some consideration. That would be a very handy tool for maintenance on bigger equipment. It raises high enough to work on equipment, but not generally high enough for a crane per se. Something like that would be VERY good for dozer maintenance. I mean really good for removing and installing tracks, blades etc. Slide a transmission into a frame from the rear, engine etc. The operator has excellent visability to the hook area in most situations.
I say its a yard crane but designed for large equipment maintenance and assembly. Very specialized and definitely something the naval construction battalion would want in order to get machines assembled and repaired quickly. The hydraulics seem to date it later than the 1940's tho.
I put my $ on that, about $0.02

Wikipedia has a "List of International Harvester Vehicles", http://en.wikipedia.org/wiki/List_of_International_Harvester_vehicles which has listed a "M5 tractor crane, 2-Ton, light tractor, TD9". I guess that is what the military called this machine. I have seen one of these up close, it was painted up nice and parked in front of a warehouse. Someone bought it, and I believe it still exists.

Certainly a real military antique - and most certainly a machine dreamed up by a Navy committee! - who never had to drive the machine!
I guess it would have been pretty handy though, when you had a lot of Navy stores to move around, and not enough labour.
Note the smooth pads, she was designed to work on concrete or asphalt in stores yards/areas, or inside a warehouse. Not a lot of lift capability, but a very stable base.
Not only would I not like to be the operator - due to the pathetic operator visibility - but neither would I like to be the mechanic who had to fix something under all that crane structure!

The Army Air Corps and the USN, in the WWII era, had many different small cranes for removing and remounting aircraft engines. The big round engines were big and heavy, and were removed frequently. Also the engines were high up in the air, especially when the flying boats (seaplanes) were ashore on beaching gear (wheels fastened to them so they could be pulled up a beach or ramp on to dry land.) The curve of the boom looks about right to clear the nose case of a large radial engine.
Smooth track pads would be required if it moved anywhere on the hardstand of an airfield. The aircraft required smooth hard compacted runways and hardstands. PSP mat in Alaska and Philippines and crushed coral in the south Pacific.

On the Forestry thread about fire and water bombers, https://www.heavyequipmentforums.co...ppression-Boomer-s-Heli-s-Tanker-s-Trucks-ect , post #63 has a picture of a Martin Mars, engines off. Imagine that little crane next to the plane, the crane might be a little short for that big an airplane, probably the right size for a PBY Catalina.
i believe that a version on this was used to as part of the equipment train used to set up towed 8in and 240 mm artillery piecies. these piecies were so large tha had to travel in several pats and dug in and assembled on site, in a process that could take up to a day.

I don't think that the artillery trains included any US Navy cranes...
That crane isn't off-road equipment.
The 2 ton hand-cranked cable spool on the crane isn't for heavy duty lifting. AC engines weighed 2,000 to 3,500 lbs. Hand cranked is good for fine positioning/control. A crew could remove and replace two or so engines a day, say four, to max it out; a hand cranked hoist is fine for that, man power can provide that four times, or so, a day. No one would be hand cranking that crane for day long repetitive lifting.
