Enthusiasts taking lift to floor (4)
I believe the answer is:
nuts
'enthusiasts' is the definition.
(nut can mean an enthusiast or fan)
'lift to floor' is the wordplay.
'lift' says the letters should be written backwards.
'to floor' becomes 'stun' (both can mean to shock).
'stun' reversed gives 'NUTS'.
'taking' is the link.
(Other definitions for nuts that I've seen before include "Potty" , "Fruit - bats" , "Stun (anag.)" , "Fruit with edible kernel" , "balls" .)
