Pallet Rack Buying Guide

Pallet Rack Buying Guide

Introduction

Pallet racks are essential for efficient warehouse storage, maximizing space, and ensuring easy access to inventory. This guide will help you understand the primary types of pallet racks and determine which type best suits your specific requirements.

 

Primary Types of Pallet Racks

  1. Selective Pallet Racks

    • Description: The most common type of pallet racking system, selective pallet racks provide direct access to each pallet. They are highly versatile and can be adjusted to fit different pallet sizes.
    • Best For: Warehouses with a wide variety of products and where accessibility is crucial.
    • Advantages: Easy to install, cost-effective, and allows for high selectivity.
    • Disadvantages: Lower storage density compared to other systems.
  2. Drive-In/Drive-Through Racks

    • Description: These racks allow forklifts to drive directly into the rack structure to pick up or drop off pallets. Drive-in racks have a single entry and exit point, while drive-through racks have entry points on both sides.
    • Best For: High-density storage of homogeneous products with low turnover.
    • Advantages: Maximizes storage space by reducing aisles.
    • Disadvantages: Limited access to individual pallets, suitable for last-in, first-out (LIFO) inventory systems.
  3. Push-Back Racks

    • Description: Push-back racks use a system of nested carts that move along inclined rails. When a new pallet is loaded, it pushes the previous pallet back.
    • Best For: Medium to high-density storage with multiple product types.
    • Advantages: Higher storage density than selective racks, allows for first-in, first-out (FIFO) inventory management.
    • Disadvantages: More expensive than selective racks, limited to a certain number of pallets deep.
  4. Pallet Flow Racks

    • Description: Also known as gravity flow racks, these systems use a sloped design with rollers or wheels that allow pallets to move forward under the force of gravity.
    • Best For: High-density storage with high turnover rates.
    • Advantages: Excellent for FIFO inventory management, maximizes storage space.
    • Disadvantages: Higher initial cost, requires precise installation and maintenance.
  5. Cantilever Racks

    • Description: Cantilever racks are designed for storing long, bulky items such as lumber, pipes, or furniture. They consist of a series of arms extending from a central column.
    • Best For: Storage of long, oversized items.
    • Advantages: Easy access to items, customizable arm lengths.
    • Disadvantages: Not suitable for standard pallet storage, lower storage density.

Choosing the Right Pallet Rack

When selecting a pallet rack system, consider the following factors:

  1. Inventory Type and Turnover

    • Determine whether you need FIFO or LIFO inventory management.
    • Assess the variety and size of the products you store.
  2. Storage Density

    • Evaluate how much storage space you need and how densely you can store your products.
  3. Accessibility

    • Consider how often you need to access each pallet and how quickly you need to retrieve items.
  4. Warehouse Layout

    • Analyze your warehouse’s layout, including ceiling height, floor space, and any obstructions.
  5. Budget

    • Balance the initial cost of the racking system with long-term benefits such as increased efficiency and storage capacity.

Conclusion

Choosing the right pallet rack system is crucial for optimizing your warehouse operations. By understanding the different types of pallet racks and considering your specific needs, you can make an informed decision that enhances your storage efficiency and productivity.

Key Components of Each Primary Type of Pallet Rack

1. Selective Pallet Racks

Components:

  • Upright Frames: Vertical columns connected by horizontal and diagonal braces. They come in various heights and depths to accommodate different pallet sizes.
  • Beams: Horizontal bars that connect to the upright frames, forming the shelves. They are typically available in step or box beam styles.
  • Wire Decking: Mesh panels placed on the beams to support the pallets and prevent items from falling through.
  • Base Plates: Plates at the bottom of the upright frames to anchor the rack to the floor for stability.
  • Row Spacers: Used to maintain consistent spacing between back-to-back rows of racks.
  • Protection Accessories: Enhance the protection of your pallet rack with items like pallet support safety bars, column protectors, end of aisle protectors, Safety netting or decking, back stop beams, etc.

Factors to Consider:

  • Load Capacity: Ensure the beams and frames can support the weight of your pallets.
  • Accessibility: Ideal for warehouses needing direct access to each pallet.
  • Versatility: Suitable for a wide range of products and pallet sizes.

2. Drive-In/Drive-Through Racks

Components:

  • Upright Frames: Similar to selective racks but designed to allow forklifts to drive into the structure.
  • Rails: Horizontal rails that guide the pallets and support their weight.
  • Entry Guides: Help align the forklift and pallets when entering the rack.
  • Bracing: Additional bracing to support the structure due to the lack of horizontal beams.

Factors to Consider:

  • Storage Density: Maximizes space by reducing aisles, ideal for high-density storage.
  • Inventory Turnover: Best for LIFO systems (Drive-In) or FIFO systems (Drive-Through).
  • Product Homogeneity: Suitable for storing large quantities of similar products.

3. Push-Back Racks

Components:

  • Upright Frames: Support the entire structure and are designed to handle the dynamic loads of moving pallets.
  • Nested Carts: Carts that move along inclined rails, allowing pallets to be pushed back.
  • Rails: Inclined rails that guide the nested carts and pallets.
  • Stop Plates: Prevent the carts from moving too far forward.

Factors to Consider:

  • Storage Density: Higher density than selective racks, suitable for medium to high-density storage.
  • Inventory Management: Supports FIFO inventory management.
  • Cost: More expensive than selective racks but offers better space utilization.

4. Pallet Flow Racks

Components:

  • Upright Frames: Provide the vertical support for the system.
  • Rollers/Wheels: Allow pallets to move forward under gravity.
  • Brakes: Control the speed of the pallets as they move along the rollers.
  • Entry and Exit Guides: Help align the pallets as they enter and exit the system.

Factors to Consider:

  • Turnover Rate: Ideal for high turnover rates and FIFO inventory systems.
  • Space Utilization: Maximizes storage space by using gravity to move pallets.
  • Maintenance: Requires precise installation and regular maintenance to ensure smooth operation.

5. Cantilever Racks

Components:

  • Upright Columns: Vertical supports that hold the arms.
  • Arms: Horizontal supports that extend from the columns to hold long items.
  • Base: Provides stability to the entire structure.
  • Bracing: Connects the columns for additional stability.

Factors to Consider:

  • Item Size: Best for storing long, bulky items like lumber or pipes.
  • Accessibility: Provides easy access to stored items.
  • Customization: Arms can be adjusted to accommodate different item lengths.

Conclusion

Selecting the right pallet rack system involves understanding the key components and how they fit your specific needs. Consider factors such as load capacity, storage density, inventory turnover, and the types of products you store to make an informed decision.
