Lift card (4)
I believe the answer is:
jack
I believe this is a double definition.
'lift' is the first definition.
(jacking is a kind of lifting)
'card' is the second definition.
(type of playing card)
(Other definitions for jack that I've seen before include "Man in navy" , "car tool" , "Sailor; flag" , "Playing card; sailor" , "elevator?" .)
