Pulled or possibly held going round a bend (6)
I believe the answer is:
hauled
'pulled' is the definition.
(hauling is a kind of pulling)
'possibly held going round a bend' is the wordplay.
'possibly' is an anagram indicator.
'going round' is an insertion indicator (some letters go around others).
'bend' becomes 'u' (a U-bend is a kind of bend - pipe under sink).
'held' anagrammed gives 'hled'.
'a'+'u'='au'
'hled' going around 'au' is 'HAULED'.
'or' acts as a link.
(Other definitions for hauled that I've seen before include "Carted, dragged" , "Pulled with great effort" , "Transported by truck" .)
