English to French Other Transport / Transportation / Shipping warehouse management

Pre-cubing of carton, pallets and trucks is done by WCS with information of orders and a transportation plan and the actual carton measurements

I'm struggling to find a french equivalent for pre-cubing, and I have doubts about the meaning of : pre-cubing of palllets ? pre-cubing of trucks (fork trucks?)
WCS (warehouse controlling system)

Thank you very much for your help.
