Dickensian scavenger, he lifted as much as possible? (5)

I believe the answer is:

hexam

'dickensian scavenger' is the definition.
(character from Dickens' Our Mutual Friend)

'he lifted as much as possible?' is the wordplay.
'lifted' shows that the letters should be reversed in order (going up in down clue).
'as much as possible?' becomes 'max' (maximum).
'max' written backwards gives 'xam'.
'he'+'xam'='HEXAM'

I've seen this clue in The Times.
