A nice clean break! It looks to me as the geometry of this connecting rod is not right,It allso appears to be a cast steel? The break on the left looking at the picture has started in the HAZ zone..(Heat Affected Zone) Metals like this need special welding procedures to be followed to be sucessfully repaired.
One has to weigh up the cost to repair compared to re placement,Yes I have reclaimed this type of connector before and had it x-rayed on completion,The part I reclaimed was not available anymore, So it was worth the excercise, but if you could have purchased it off the shelf my sweat would not have paid for it self. Only you can judge that.
I have seen them unload heavy equipment like that before here in Australia,But not to the extreme of wheel standing the truck
