We have the cylinder at the back of the two arms, then we have a pivot point at the top of the elevator a few inches away from the cylinder. If we did just that both arms would open but they would sway back and forth, so we added a cross bar that crosses over the pivot point on each side the same amount to keep it square and opening equally.

in the picture you can see that the bar on top is a bit in front of the pivot and on the opposite side it is a bit behind the pivot.
