I have warre hives (just as not intending to harvest) and they have the advantage of the smaller boxes and so less weight. They come with or without frames and normally have the long strip handles so good and solid to grip. With larger hives it often helps to have two people to manipulate them anyway.
There are some clever tools for separating boxes, I saw a version of this somewhere for 200euros, as ever can't find it now
Possibly someone could make it for less. The dimensions for it are here as are loads of other ideas and designs.
Beekeeping with the Warré hive -- Lifts
Can be used for inspections by lifting a box and using a mirror (David Heaf's method) to look up into the bottom of the box.
I am in france so no state inspections so something to consider in the uk ?
Means individual boxes can be removed while the others stay in place, so no 'jenga' effect. So just one 35x35x20cm box to work on at any one time.
If you watch the video you can see how it separates enough to insert or remove a box from anywhere in the stack. Removing the top box for harvest (the Warre way) with this would mean lifting it up and putting the top cloth over the exposed box so bees are calm inside while the top box of honey is removed. Then lift the stack to add an empty box below (ideally just 3 maybe 4 in total).
The thing with this is that it is stable and controlled, should not suddenly move or overbalance.
I am making one for myself simply because they say the bees hardly notice as the stack stays in line and no putting various bits on the floor etc. Basically one box goes into the air and one is removed or added, all very calm and controlled.
