Pat Franklin should get a younger and fitter friend or apprentice and exchange
experience for muscle.  How often and why is it necessary to move a hive?
Rethink your methods.  With a bad arm can supers be lifted off for removal or
for access to the brood box?  Try a long hive so everything is all at a level
and can be worked from a wheelchair if necessary.  As my granny used to say,
"Its no use getting old if you don't get crafty"
