I've been messing with some CRAZY TBH ideas and was hoping to get some input. Often TBH users end up wanting to expand, but find themselves with some limitations. One common solution is to install supers over their TBH. I think this is a great solution. While pondering this I came across another thread discussing the Dadant Hive design. This thread highlighted the benefits of installing super frames perpendicular to the brood frames. I think this is another great idea. One potential drawback is the Dadant design uses square boxes and these can get pretty heavy. Well, I like the idea of lifting top bars, not boxes. Plus I have a bulging disc so if I can avoid lifting boxes, then great.
This is a 4' long Top Bar Hive with a long super. I started with two supers (think Langstroth square boxes), but ended up making it one long box for access reasons. As you can see in the drawing below I needed a long super to gain access while part of the super cantilevers over the TBH. The super frames are placed perpendicular to the brood frames. Also, the super sits on Teflon bars so I can easily slide the box along the Top Bar Hive. The cantilever works in theory, but I don't love it. I was kind of stuck with the 4' TBH simply because I think anything over 4' is too long. The other thing is the entire hive is getting to be pretty big. Both TBH and Dadant designs use followers to restrict space so maybe the large size isn't a big problem.
I can see how at some point I may end up with a few shallow supers stacked and having to lift them by hand anyway, but at least this way I can check the brood by sliding the supers and not having to lift boxes. So what do you think?
Below are some concept drawings. Also, here is the link of that other thread I mentioned. https://www.beesource.com/forums/show...-disadvantages
I felt 4' was too long considering the depth of the bottom box. So I drew the same idea with a shorter bottom. The last picture (not the attachment) shows what would amount to a TBH that is twice the length of a Lansgstroth. This would limit the 'sliding' to one column of supers, rather than two.
