Daifuku Webb's unit load is a high-density pallet buffer designed to maximize vertical storage space while maintaining a compact footprint. Several models are available to handle pallet loads from 1,100 to 6,600 lbs. (500 to 3,000 kg) and rack heights up to 118 feet (36m). The unit load can also be used to store long or bulky items, hazardous materials, frozen items (to -40 degrees C/-40 degrees F) and low-noise applications. In addition to a standard unit load, Daifuku Webb also offers double-deep rack configuration.
