Large gold robbery cleared out truck (5)
I believe the answer is:
lorry
'truck' is the definition.
(lorry is a kind of truck)
'large gold robbery cleared' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'cleared' says to hollow out the word (remove centre letters) (the inside letters are cleared out).
'robbery' with its centre removed is 'ry'.
'l'+'or'+'ry'='LORRY'
'out' is the link.
(Other definitions for lorry that I've seen before include "Commercial vehicle" , "Transport vehicle" , "Large motor vehicle for transporting goods" , "Heavy goods vehicle" , "HGV" .)
