Lift, open and restart after repairing (11)
I believe the answer is:
paternoster
'lift' is the definition.
(historic type of lift)
'open and restart after repairing' is the wordplay.
'and' means one lot of letters go next to another.
'after repairing' is an anagram indicator.
'open' after 'restart' is 'restartopen'.
'restartopen' is an anagram of 'PATERNOSTER'.
(Other definitions for paternoster that I've seen before include "that could take people to a different level" , "supplication" , "One can get uplifted by this" , "The Lord''s Prayer" , "a continuous lift" .)
