AUTO-STAK® ZX2
Automated Parts-To-Person System

The only system on the market with a capacity up to 6,000 lbs.

Store virtually anything - cost effectively and with quick access.

The AUTO-STAK® ZX2 Automated Parts-To-Person System has been designed to meet a broad range of storage and retrieval applications in manufacturing, distribution, retail, and warehouse operations. The combination of optimal storage density, flexible, efficient storage strategies, ergonomics and security makes the AUTO-STAK® ZX2 from Rapistak a unique storage management solution.

The modular AUTO-STAK® ZX2 Automated Parts-To-Person System is an enclosed system of vertically and horizontally arranged trays that are stored on either side of the unit. There is an extractor device located in the center, which automatically delivers steel pallets with the stored items into the access opening at the push of a button or scan of a bar code. The device is modular in its construction with the ability to change its length and number of access openings pre and post construction. Depending on the ceiling height, at least 85% of a conventional storage system's occupied floor space can be recovered.

Variable size trays can be provided to accommodate various size products

The length of the unit can be modified quickly and easily, and additional side access openings can be retrofitted to meet future needs.

Various work stations are available.

AS/RS Systems

Paint drum AS/RS System

Paint Drum Capacity: 770 lbs
No. of Storage Locations: 1,476
Application: Class 1, Division 2, Group C
No. of Movements in 7 Hr Shift: 100
PLC Controls: A-B ControlLogix 5500
HMI Terminal: A-B PanelView 5500

Using bar codes to track the location of each paint drum, this AS/RS System is capable of keeping track of 1,476 paint drums. With the installation of this system the customer was able to free up much needed floor space and reduce access times for production.

  • Aisle Width: 98" face to face of rack
  • Vertical Lift Speed: 32 fpm with flux vector variable speed drive
  • Trolley Speed: 40 fpm with variable speed drive
  • Bridge Speed: 250 fpm with variable speed drive
Stacker Construction
  • Modular component design
  • All parts designed for 100% duty cycle
  • Welded steel frame construction
  • Single tube mast construction
  • Drive and idler wheels are double flanged spheroidal graphite cast iron
  • Wheel bearings are tapered roller type
Fork Carriage:
  • Welded steel frame construction
