Thread: Did someone say articulation?

Here's a link to some interesting vehicles, including the one in the original post (half way down the page). I'm looking for a technical description or drawing of the Willock Swivel Chassis/Frame which was an aftermarket modification available on a variety of make and GVM trucks. I'm assuming the connection would have to be a decent roller bearing, but I also wonder if there was any type of spring or dampening.

Aaah! you have got to love that Johnny Cash song "One Piece at a Time"

Kinda like how I rebuilt my series 2a GS

Here is a paragraph related to the original photo.

1953 Dodge Power Wagon equipped with Willock Swivel Frame The Willock Swivel Frame was created by the owner of the Willock Truck Equipment Company, a manufacturer of specialty equipment for on- and off-road trucks. Willock’s invention separated the front and rear halves of the chassis, allowing the two sections to move independently and minimizing the likelihood that the frame and cab would crack or break during heavy use or when navigating extremely uneven road surfaces.

I note that there is a chain between the running board and the cargo body, limiting articulation.

That would be do-able to a Defender 110 trayback or 130 DC with separate rear body,would be easier with a "C" section chassis like a T*****a 70 series

Or

An AS/AL series Inter 3 tonner

The driveshaft would have to pass through the centre of the swivel, to what would essentially be a centre bearing at the rear section of the swivel. On a (relatively) short wheelbase such as the Powerwagon, UJs would be severely taxed.

The fabrication could be easily achieved on any type of chassis, with suitable strengthening and gussets to spread the load, Kev. The problematic issues that I see, are driveline angles which optimally do not exceed 3*; impossible to achieve with a short wheelbase platform.

I'm aware that wide angle UJ's are available for Land-Rovers as they are used in UK extreme competition vehicles
