Daifuku'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 500 to 3,000 kg (1,100 to 6,600 lbs.) and rack heights up to 36m (118 ft.) The unit load can also be used to store long or bulky items, hazardous materials and it is also ideal for freezer (to -40 degrees C/-40 degrees F) and low-noise applications. In addition to a standard unit load, Daifuku also offers double deep rack configuration.
Primary Problems Addressed:
Bulk buffering and storage of raw material and/or finished goods
Work-in-process buffering (temporary storing) for large items
Embedded point-of use for assembly or kitting operations
Replacing conventional static rack or narrow aisle rack

A unit load is comprised of an:
Storage Retrieval Machine (SRM)
On-board and end-of-aisle controls
Daifuku's unit load stores and retrieves items placed on pallets, euro pallets, box pallets or roll box pallets. Items are transported to/from the unit load by conveyor, forklift, Sorting Transfer Vehicle (STV) or Automatic Guided Vehicle (AGV).
Variable speed control
Fast, accurate load transfers
Modular design allows for easy expansion
Regained floor space
Inventory accuracy and control
High-speed stable storage/retrieval operation
Reduction in spoilage/damage
Simple operation and maintenance
The availability of overhead space in the facility determines rack height. Aisle length and the number of aisles are based on available floor space. Load size and required throughput affects the speed and is considered to determine system configuration of a single or dual shuttle and single or double-deep storage.
