once upon a time i made a 4x4 wood a frame to use with chain hoist to unload my 1800 lb nardini lathe from back of pickup. worked marvelously. it was simply 4pcs of 12' 4"x4" with 5/8" all-thread through the ends & splayed like a teepee. with chain hoist on rod.

I now want to load/unload from skid loader type trailer a 5800 lb vmc.

gives compressive loads.
says 4x4 x 12 are good for 3,300 each, at #2 grade. (i'm sure menardws is LOW)
of course I cant ensure my teepee is completely uniformly loaded per leg,
4x6 is 5200 lb @ #2 grade
shall I uprade my design to 4x6 or 6x6?
