No, the actuator can be attached to bridge close to the pivot point on the bottom. It has enough power to push it up from there and stay out of aisle.
That looks really slick, Mike!
Mount the actuator base on a cross member attached to the rear outside edge of the stand/base. That will move it back, mostly out of the aisle.
Then fit the height position with the actuator nearly fully extended and the bridge held in a 90° vertical position. Attach the bridge mount near the pivot and the base will mount where it's located/falls. That's where the mounting cross member will need to be.
I think the grandchildren will be playing with the bridge a lot.
