Tons to carry? Lifting that will get you in trouble (5)
I believe the answer is:
theft
'lifting that will get you in trouble' is the definition.
'theft' can be an answer for 'lifting' (thesaurus). I am not certain of the rest of the definition.
'tons to carry?' is the wordplay.
'tons' becomes 't'.
'to carry?' becomes 'heft' (I can't explain this - if you can you should give a lot more credence to this answer).
't'+'heft'='THEFT'
Can you help me to learn more?
(Other definitions for theft that I've seen before include "Pilfering" , "Taking of another's property" , "Action of stealing" , "Lifting" , "Burglary" .)
