Pallet Storage Block stacking: Stored on the floor Pallets are stacked on top of each other Stack ability and stack height are dependent on the following factors: Weight General stability SOPs/Safety/OSHA acceptable safety limits Floor lead restrictions Physical height availability Crush limits
Pallet Storage Block stacking: Use when retrieving product based on LIFO (Last In First Out) Not optimal for FIFO (First In First Out) Best for large number of pallets for same SKU, low cost, no racking
Pallet Storage Stacking Frames: Portable and collapsible frames Build as needed Steel uprights with steel decking Easy to collapse and storage is compact Use for loads/pallets that are unsafe to stack on top of each other
Pallet Storage Single-Deep Pallet Rack Permanent racking only one pallet deep Can store multiple SKUs in same column and row Best to be used with loads that are not stackable and SKUs with only a few pallets of product
Pallet Storage Double-deep pallet rack Permanent racking two pallets deep Use with SKUs with five pallets or more of product AND retrievals that are in multiple of two pallets Use with high volume SKUs Can save significant space over single-deep pallet racks
Pallet Storage Drive-In Rack: Able to drive into the rack Racks are up to ten pallets deep Pallets are stored on rails instead of decking Use with SKU quantities of five pallets or greater Best when have SKU totaling 20 pallets or more Downside, much slower production due to confined space
Pallet Storage Pallet Flow Rack Similar to Drive-In Rack but has rollers on the rails Pallets are removed FIFO from the side opposite from which it was loaded As pallets are removed the remaining pallets roll forward Use with SKUs totaling ten pallets or more
Pallet Storage Push Back Rack Similar to pallet flow rack Pallets are removed LIFO from the same side they are loaded Load new pallet by pushing existing pallets back Remove a pallet and the remaining pallets flow forward
Pallet Storage Mobile Pallet Rack Series of single deep racks abutted next to each other with no aisle in between Aisles are creating by pushing or cranking rows apart Upside: considerable space savings Downside: very slow production
Material Handling Equipment Walk Behind Pallet Jack May be manually operated or motorized Operate from a walking position Motorized versions may be capable of reaching low heights Best for short distance move
Material Handling Equipment Counterbalanced Lift Truck Lift truck with the weight on the back end to counter the weight of the load on the forks on the front end
Material Handling Equipment Straddle Truck: Instead of using counterbalance to provide stability, this truck uses outriggers to straddle the pallet.
Material Handling Equipment Side Loader: Loads from the side. Forks are located on the side not the front. Allows the operator to travel down the aisle without having to turn the truck to retrieve a pallet Downside: Can only reach one side of the aisle from a given direction of travel.
