I agree with Dawn and Tim that to reduce the weight of the super remove some frames and then lift. I use another 8f super with a base board attached.
Having said that I have now got Long Langstroth hives with flow frames. You only need to lift a frame, flow or normal, at a time. Before you google use the search function on this forum and you’ll see a few from the members here.
