Winch (8)
I believe the answer is:
windlass
'winch' is the definition.
(synonyms)
This is all the clue.
(Other definitions for windlass that I've seen before include "Weight-lifting device" , "Axle for rope or chain used in hoisting" , "lifting apparatus" , "One that gets wound up" , "Drum for reeling in heavy items by rope or chain" .)
