I haven't tried this yet and, fortunately, haven't needed to, however I 
have been thinking about it. It would be difficult for a 
wheelchair-bound person to reach far and TBHs tend to be long. Also, if 
worked from the side, one has to twist the spine to reach both ends of 
the bar.  The solution I have in mind in case the need arises is to 
have a TBH that can be tilted sideways through getting on for 90 
degrees so that the wheelchair-bound person can reach both ends (now 
top and bottom) of a bar and draw it forward to remove and examine or 
harvest it. The side might need an extra supporting strip on the near 
side as, upon replacement of the bar, it would tend to slip down due to 
a phenonemon called 'gravity' which appears only after the propolis 
seal has been broken.

I haven't thoroughly thought through the mechanism for turning the 
hive.  Possibly, if slung on cables, by pulling a lever the far side 
could be raised to twist the hive towards the beekeeper.   
Alternatively, the hive and stand could be designed with opposing bolts 
at each end so it could simply be swivelled with little effort.
