Hated the load being moved (7)
I believe the answer is:
loathed
'hated' is the definition.
(loathing is a kind of hating)
'the load being moved' is the wordplay.
'being moved' indicates anagramming the letters.
'the'+'load'='theload'
'theload' is an anagram of 'LOATHED'.
(Other definitions for loathed that I've seen before include "Detested and abominated" , "'Abhorred, detested (7)'" , "Hated" , "Regarded with disgust and hatred" , "Cordially detested" .)
