Hensley Arrow: How does it REALLY work?
There have been several discussions on this hitch that have become somewhat 'controversial'. I am NOT trying to stir this controversy/bashing back up. Instead, I'd like to see a good, intelligent di...

Thanks a lot, you guys! I go away for 10 days and come back to find 47 new posts in this thread that only show that you're starting over! :E:W
I suggest that if you are really that curious as to why a couple non-Hensley owner engineers (Ron and I) are not giving in to the concept of the Hensley ever being a "locked" hinge hitch - you should try to contact someone at Hensley who might (I'm sure they have more valuable things to do) take an official position on the topic (the piece that Milt quoted from the Hensley website doesn't count because it was misinterpreted).
The problem that has been missed by some of you is whether or not any of the 4 pins in this 4-bar linkage are fixed. As long as they are not and are not restricted from pivoting by anything other than the linkage itself, the only "locking" that CAN occur is outside of the linkage, e.g., the frictional contact that any of the involved vehicles' tires have on the ground that prevents the angulation (trans-rotation) that the linkage is forced to go through in order to pivot. This does NOT mean the linkage itself locks, but it does make the linkage ACT like it's locked in most applications.
BTW Will, the "tug" that that TV places on the TT does relatively little to resist the trans-rotation of the hitch in comparison to the trailer tires not sliding side-to-side laterally in a manner that accomodates angulations that would be forced by the linkage in order to pivot.
I thought we covered this back in June. ???
