Swivel Frame Image...

I pulled the bed off the swivel frame. This image is from the ditch in front of my house.

If you think that's cool....

Jonas,

Your pix apears to show the rear drive shaft nearly hitting the tunnel of the rear pivot cross-member, yet the limit chain is nowhere near coming into play. How much further can you go before you need to radio your wife, "Houston, we have a problem."?

Hey, Jonas,

Pretty awesome machine. I'm not real clear on it though: is this a stock Dodge issue, or something you cooked up one long night with a welder and a pile of steel?

I had designed something similar for a different type of vehicle and was surprised to hear of your Dodge already built that way. Gotta be a real kick to drive!

I noticed the driveshaft also. That truck has to be a blast to drive. Looks good!

willock swivel frame

I read an article and found pictures of the willock swivel frame and can't remember where. I know that the army had about 10 or so of these in M37's that they were trying and I've seen a picture of a dump truck that was used in the willock advertisment. I don't know if it was offered from the factory or as an aftermarket add on but I do know that you have an exceptionally RARE truck here............ Anybody have an M37 frame with a willock swivel in it that they don't need and would like to donate to my restoration project please drop me a line, I'd load it on the roof of my wifes (she would kill me) 2005 Ford Focus if I had too just to get it here.

The swivel has the chains set so the driveline wont hit the crossmember, it's close, but it wont hit unless both chains break.

I never heard of the army modifying a M37 for the swivel. Theres a guy who built his own in a M-37 for the top truck challenge, if that's what you are thinking of.
Theres no point to it in a M37... the truck flexes as much as the swivel with stock suspension, and rides a lot smoother than the swivel.

Willock corp. put the swivel mechanism in about a total of 40 Civvie type power wagons. This was a special order item like a dump bed or a Davey PTO or what not. It was not installed at Dodge Truck mound road facility. It was installed by Willock or Truckstell corp.

A machine shop in Florida apparently made a few also in the late 50's and early 60's.

The earliest Power Wagon with the original Willock swivel I've seen was a '50 and the last was a '55 or '56.

I have the original Canadian Patent (long expired) from Harry Willock's grandson The original design was applied for in 1946, and was originally intended for 2 ton and larger 2wd trucks.
It's purpously crude and strong, just lots of steel and big mechanisms.

I have lots of vintage literature and sales brochures on the subject.

swivel frame

Jonas

I remember a fellow having a swivel frame PW in Northern British Columbia about 30 years ago. It had gin poles on the front and a flat deck. He was a prospector and once told me that the PW would go almost anywhere his Cat would go. He use to haul tremendous loads into some rugged back country with it.
I have a friend still living in the area. He is going to look around to see if the truck is in the area.

Really appreciated reading about your knowledge of them.
