Warehouse truck (8)
I believe the answer is:
forklift
'warehouse truck' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for forklift that I've seen before include "Truck for carrying loads in warehouse" , "Truck for stacking goods" , "Truck with mechanism to pick up loads" , "Truck for raising loads" , "Small load-lifter" .)
