Does any one have a picture of a gate they have made or had made with a wheel on one end so it rises when opening up the hill , have seen some with a sliding bottom hinge to allow the gate to rise and have seen some made of box section that are drilled and bolted at every joint so they pivot upwards when they are opened and the end wheel rises up the hill , need something 15’ , five bar , don’t want to use 2 smaller gates that meet in the middle as they are a more time consuming to open , thanks in advance
