The Vidmar® STAK System stores and retrieves heavy, bulky items vertically—up to 18 feet high—with an adjustable racking system, comprised of removable, adjustable pallets and a captive lifting and handling device. The STAK System creates up to a 70% smaller footprint than horizontal beam rack storage, and can fully operate in as little as 250 square feet. One operator can pick and retrieve a heavy load, up to 4,000 lbs., in as little as two minutes saving valuable time. A single operator can control exactly where items fit best with dynamic adjustable pallets eliminating wasted storage space. STAK is also available as a HazMat system designed for 55-gallon hazardous material drums.
