UNITED STEEL PRODUCTS COMPANYUSP PUSH-BACK RACK:Using your warehousing space to the maximum!INCREASED DENSITY.Today‘s challenge in warehousing is to store an ever increasingnumber of pallets with an ever increasing number of productsin a fixed storage space. These two factors work against eachother, unless you utilize USP Push-Back. Push-Back storageincreases the pallet count, while offering many more pick facesthan traditional high density storage systems.How does USP Pushback stack up?Typical occupancyHandling costsNumber of pick faces per towerRandom storage all levelsStock rotationRack/Product damageNumber of products applicableEfficient bottom level case pickFloor Storageor Drive-inUSPPush-Back50-60%HighOneNoRotate towersHighFewNo85-95%Low# LevelsYesRotate lanesLowManyYes

Thesemultiple lanes allow rotation to achieve first-in/first-out. USP Push-Back systems can be configuredto attain up to 100% more pallets stored than standard pallet rack and equal or greater increases overpoorly occupied drive-in or floor storage configurations.SYSTEMFLEXIBILITYUSP Push-Back is available in2, 3, 4, 5 and 6 deep stylesand can be arranged as backto back islands or standalone bays. Number of levelshigh is restricted only byyour lift truck’s reach.No special fork trucks arerequired.

USP PUSH-BACKFeatures & BenefitsUSP push-back is loaded with safety features andsmart innovations. Its unique design providestrouble-free operation, and structural steelpush-back components ensure long life in tough warehouse environments.Low Profile: USP push-back has alower profile than other cart typesystems. This allows for extra liftclearance, and possibly anadditional storage level.Linked Carts: Carts are linked whenextended, elimination thepossibility of single pallethang-ups, which can lead touncontrolled pallet load movement.No push-back system is completewithout this importantsafety feature.Lift-Out Protectors: Each push-backcart is equipped with lift-outprotectors, which prevent accidentaldislodgement of carts byforklift operators.Gauge Bars: Maintain the properdistance between cart rails. Thisassures precise alignment and smoothoperation of the cart nesting system.Flanged Steel Wheels: Our wheelsare manufactured from solid steeland equipped with heavy dutybearings. Sturdy 5/8” shafts arewelded to the carts and are oversizedto withstand shock loading,capacities of up to 1,400 lbs.per wheel.Multi PurposePlate: Acts as–Height gauge: Ifthe load is highenough to clearthe safety stop,then the palletwill notprematurely move the awaiting cart. Strip-offstop: If an operator has his forks in an impropertilt position, the safety stop will catch thebottom of the pallet and “strip” it off his forks. End stop: The end stop,situated on the lowest cart, prevents pallets from shifting beyond the frontload beam. Push plate: Pushing on the plate with the last pallet beinginserted into the lane ensures proper placement on the rails as well asguaranteeing safe clearance of the cart. Full lane indicator: The operatorcan tell if a lane is full by the absence of the plate. If it is not showing,the last cart has been pushed back by the last load and the lane is full.THE STORAGE RACK COMPANYPHONE: 570-476-1010 FAX: 570-476-4358e-mail: usp@usprack.comwww.usprack.com

THREE PRINCIPLES OF SUCCESSFUL PUSH-BACK APPLICATIONS1. First-In/First-Out Stock Rotation2. High Occupancy3. Random StorageRule #1: Select products to be stored thathave at least 3 times the lane depth in averagepallets in inventory.Most storage facilities have products that range fromone pallet per item up to many pallets per item. Theaverage amount of storage per item should be usedto select optimum lane length.The table shown will yield occupancy rates of80% – 90%. The higher the number of lanes perproduct the higher the occupancy rate.PALLETS PER PRODUCTLANE DEPTH1 – 4 . . . . . . . . . . . . . . . .

This will result inno more than one part lane, per lot code.This procedure will ensure FIFO Stock Rotation(First in – First Out).Rule #4: Use random storage to minimizehoneycombing. This will enable you to maximizeyour storage facility.Random storage in any of the lanes that becomeavailable will allow the storage requirement for anyitem to grow and shrink as necessary. Fixed locationswould require storage to be preset for every item atits peak. Exceptions could be made for bottom levelcase picking with fixed locations.THE STORAGE RACK COMPANYPHONE: 570-476-1010 FAX: 570-476-4358e-mail: usp@usprack.comwww.usprack.com
