Different idea, with the true platform and the 4 separate pins. For me, I'd need triangulation for the legs. I would put gussets on tops and bottoms, and maybe some cross bracing on the bottoms between the outer "sleeves".
This would be a minimum of what I'd do.
Hey everyone. Sorry to rush in on this thread, but you guys were talking about some Walker jacks... I have an old Walker that I'd like rebuild, but I can't find anything online to even acknowledge its existance. It's a Walker Air Lift, Model J-196 Series B 3000# front end lift. Ever heard of it?
