28 OCTOBER 2014 • FOOD LOGISTICS be stored and retrieved. A fundamental benefit of the flow-rail system is that there are no angles required as there are with a pushback or flow-through racks. "You get much better use of the clear stacking height of your building and that can translate into higher storage capacity in some buildings," Wulfraat says of the flow- rail system. Earth2O, a bottled water manufacturer based in Culver, Ore., recently installed a flow-rail system at its warehouse, notes Mike Peterson, vice president of operations. The company had been stacking cases of 6-, 12- and 24-unit shrink-wrapped packs of 12-oz., 16.9-oz., 20-oz. and 1-liter bottles on the floor. The Exglobe flow-rail system installed within the last few months has improved stor- age density, Peterson says. Peterson says he investigated other racking options and determined the flow-rail system is the most cost efficient. He says there is no need for a forklift to enter an aisle to retrieve cases. This cuts down on labor, travel time and forklift-caused damage. It doesn't take any longer for the forklifts to stack the pallets than it did before, he adds. The pallets are stacked two and three levels high in the flow- rail system. The Earth20 warehouse now stores 1,500 pallets compared to the previous 450 pallets, Peterson says; seven to 10 days' worth of inventory versus two or three days. Seismic challenges for rack strength This year's earthquake on the West Coast generated interest in rack strength. Hannibal Industries developed a rack that is designed to absorb a lot of force, such as that which can be caused by a seismic event. Hannibal Industries tested the Tube- Rack against a standard structural rack using a wrecking ball simulating a forklift traveling two miles per hour. The forklift hit the racks direct, angled and head on. Steve Rogers, vice president at Hannibal Industries, says the standard structural rack was not able to withstand the force of the forklift while the TubeRack was able to bounce back and yield minimal damage. The TubeRack is designed to respond to a seismic event in a way that allows the rack to move with the motion rather than resisting it, Rogers says. The TubeRack can also feature a double- wide design provided by Twinlode, another manufacturer, that allows loading or unload- ing two pallets at a time while reducing han- dling costs, Rogers says. The tubular design also makes it possible to ship more product within trucks and containers and ultimately reduces freight costs. Some building codes on the West Coast are requiring larger foot plates due to seismic events, notes Kevin Rowles, president of Storage Solutions, a storage solution distrib- utor and installer. Some building codes have increased pallet rack foot plate requirements from eight square inches to 12 square inches. "Every time the earth shakes, the plates get bigger," he says.

Orbis Corp. recently enhanced its 40- by 48-inch RackoCell, a pallet engineered specifically to meet the needs of the food manufacturing industries where hygiene, durability and ease of washing are required. The RackoCell is molded in one piece from polypropylene copolymer to offer enhanced stiffness and edge- racking performance up to 2,200 pounds, and features a flow-through design that washes and drains quickly for high sanitation. ◆
