Go with a large cross section round tubing for the beam material, this will hold up better than rectangular tubing for twisting forces from wheel loads.
They twisted after three years of abuse, cambering the wheels a bit (see the teardown video). I operate my equipment hard like a cat D9, so if I went back to walking beams I would use a generous cross section round tubing to take the torsional stresses. As the saying goes, when in doubt build it stout (and then some for tracklayers)!
Impressive work. Really enjoying your build.
Building something similar to your walking beams , they look very strong .

what size steel did you use for the axle in this video?
Nice work and love the machine , How's the walking beams holding up , Wheels not trying to tow in .
