Unit Load

1. What is a unit load?
  • "A unit load combines individual items or items in shipping containers into a single "unit" that can be moved easily with pallet jack or forklift truck. A unit load packs tightly into warehouse racks, intermodal containers, trucks, and boxcars, yet can be easily broken apart at a distribution point, usually a distribution center, wholesaler, retail store, etc." []
