After a successful liftoff of the shell of my 1953
Liner, see thread under 54 Liner...can't seem to get a 53 category opened
, we discovered an unusual frame.
The frame rails are 4" C channel with a welded plate forming a box beam at the double axle. The cross ties are 2"x1.5" angle. The outriggers are a custom shape C with a 2" top and 1" bottom flange...the web is 3" tall.
Surprisingly the cross members are covered with a U shaped channel of alclad that is 4" deep.
Primarily the belly pan is attached to these alclad channels and then perhaps one or two rivets into the bottom flange of the outrigger.
For a 29' long trailer there is almost nothing supporting it and frankly I can now see why these monsters just didn't survive.
So I'm curious what others think of this. Has anyone else come across such a light frame on such a large trailer? Any successful re-engineered frames out there? I'm hesitating in adding much, the trailer, though beaten was not in completely terrible condition, certainly the frame has survived in pretty decent shape.
I'm considering beefing up the outriggers, replacing them with a heavier version and perhaps welding a angle under the outrigger to provide additional stiffening. I'm also thinking to add an addition cross member at the rear and then perhaps an additional lower angle at every second member.
I'm very curious what others think...
