Types of Pallet Racks
Diverse rack systems cater to varied needs. Common types include selective‚ drive-in‚ push-back‚ flow‚ and cantilever racks‚ each offering unique storage solutions.
Selective Pallet Racks
Selective pallet racks represent the most common storage solution in many warehouses. They offer direct access to every pallet on a first-in‚ first-out (FIFO) basis‚ making them incredibly versatile. Characterized by upright frames and horizontal beams‚ these racks allow for 100% accessibility of stored goods.
Identification is straightforward: look for uprights with step beams or box beams connecting them. The open rack structure facilitates easy loading and unloading using forklifts. While offering maximum accessibility‚ selective racks typically have lower storage density compared to other systems. They are ideal for a high volume of different SKUs and fast product turnover‚ making them a foundational element in numerous distribution centers and storage facilities.
Drive-In Pallet Racks
Drive-in pallet racks maximize storage density by allowing forklifts to drive directly into the rack structure. Pallets are loaded and unloaded from the same side‚ creating a last-in‚ first-out (LIFO) system. These racks utilize rails along which the forklift travels‚ supporting the pallet’s weight.
Identifying features include the lack of uprights between rows‚ replaced by a single continuous row of rails. This configuration significantly reduces aisle space‚ increasing storage capacity. However‚ access is limited as you must remove pallets in front to reach those further back. Drive-in racks are best suited for storing large quantities of a few SKUs‚ particularly those with slower turnover rates‚ optimizing space utilization.
Push Back Pallet Racks
Push back racking systems offer a high-density storage solution utilizing nested carts on inclined rails. Forklifts push pallets onto these carts‚ which then roll back along the rails when the next pallet is loaded‚ creating a LIFO (last-in‚ first-out) system. This design maximizes space while maintaining relatively good accessibility.
Key identifiers include the angled rails visible within each bay and the nested carts. Unlike drive-in racks‚ push back allows for multiple pallets deep within a bay without completely blocking access to others. They are ideal for storing multiple SKUs with moderate turnover‚ offering a balance between density and accessibility. Regular inspection of the cart wheels and rails is crucial for smooth operation.
Pallet Flow Racks
Pallet flow racks‚ also known as gravity flow racks‚ utilize a series of inclined rollers within a rack structure to move pallets forward as each one is removed. This creates a FIFO (first-in‚ first-out) inventory system‚ perfect for date-sensitive goods like food or pharmaceuticals. They significantly reduce labor costs associated with pallet movement.
Identifying features include the visible rollers or wheels within each bay‚ and a slight downward slope. Unlike push-back racks‚ pallets move automatically without forklift intervention. Flow racks are often used in distribution centers and warehouses needing efficient throughput. Regular maintenance of the rollers is vital to ensure smooth‚ uninterrupted pallet flow and prevent system jams.
Cantilever Racks
Cantilever racks are uniquely designed for storing long‚ bulky items that traditional pallet racking struggles with – think lumber‚ pipes‚ or furniture. They feature uprights with horizontal arms extending outward‚ lacking front columns to obstruct loading and unloading. This open-front design provides easy access to each stored item.
Identification is straightforward: look for the single‚ projecting arms without obstructing uprights. Capacity is determined by arm length‚ upright height‚ and baseplate stability. Cantilever racks are commonly found in lumberyards‚ metal warehouses‚ and building material suppliers; Proper baseplate anchoring is crucial for stability‚ especially with heavier loads‚ ensuring safe operation and preventing tip-overs.
