Push-Back Racking

Detail

Pushback racking revolutionizes storage by enabling the placement of pallets from 2 to 6 deep on each side of an aisle, surpassing the storage density of conventional racks. This innovative system combines the density of drive-in racks with the added benefit of single-lane selectivity.

Wheeled carts or rollers are strategically positioned in each lane, with a pallet initially placed on the top cart. Subsequent pallets are loaded by pushing the existing ones backward, revealing a new cart or roller beneath. As pallets are retrieved, the rear ones effortlessly move forward, ensuring a streamlined and efficient process.


Types of Push-Back Racking:

There are two primary types of push-back racking: push-back with shuttles and push-back with rollers. The shuttle system involves depositing each pallet onto a movable shuttle on rails, while the roller system employs beds fixed to the structure at a slight incline. Both types provide an efficient solution for warehouse or distribution center inventory management.


How Push-Back Rack Works:

The pushback rack system consists of carts or rollers on inclined rails. Forklifts load pallets onto the top cart, pushing the previously loaded pallets backward as new ones are added. Unloading is a reversal of this process, bringing the pallets to the front for easy retrieval. This system is particularly advantageous for companies with high-volume inventory turnover.


Advantages of Push-Back Racking:

  • Offers both selective and high-density storage.

  • Provides 2x to 3x more storage space compared to standard selective racks.

  • Requires minimal maintenance and reduces potential damage to uprights as forklifts don't enter the system.

  • Incorporates safety mechanisms for controlled braking in both shuttle and roller systems.

  • Compatible with other adjustable pallet rack systems, making it suitable for cold storage or freezing.

  • Excellent space optimization leading to cost savings.

Disadvantages of Push-Back Racking:

  • Only front-row pallets are readily accessible.

  • Slight slope may result in a loss of vertical height storage.

  • FILO rotation method may not be suitable for items requiring precise date rotations.

  • Limited to 4-5 pallets deep.

  • Load integrity is crucial for effective push-back, and some loads may not be robust enough.

PushBack Racking System Structure:

The system comprises a base metal structure with frames, beams, crossbeams, and dynamic profiles. Shutters or rollers generate movement within the structure, accompanied by safety accessories for load control. Each component plays a crucial role in ensuring the efficiency and safety of the push-back racking system.

Dimensions of Push-Back Racking System:System dimensions vary based on pallet depth, with typical systems accommodating conventional GMA pallet sizes ranging from 8′ to 28′ deep. Heights are limited by facility constraints, upright strength, and forklift reach, typically reaching 16′ or 20′ tall.


Choosing Push-Back Racking:Consider a push-back rack system if:

  • Your application involves minimal order picking.

  • Multiple-product storage solutions are required, combined with static, drive-in, or pallet flow racks.

  • Items are non-perishable with a long shelf life.

  • The number of pallets per SKU falls within the range of 6 to 30.
