High density warehouse racking is a racking system designed to maximize warehouse space utilization. It achieves higher storage capacity per unit area by reducing the number of aisles and increasing the storage density of goods. This type of racking is suitable for scenarios with large storage capacity, fewer SKUs, or controllable frequency of entry and exit.
Common types of High Density Racking include:
1. Drive-In / Drive-Through Racking
Features: Forklifts can drive directly into the rack to access pallets.
Applicable: Large batches, few varieties, suitable for LIFO or FIFO.
Advantages: Save aisle space to the maximum extent.
2. Push Back Racking
Features: The pallet is placed on the slide rail, and the rear pallet pushes the front pallet to slide backwards.
Applicable: LIFO system, high access efficiency.
Advantages: Each cargo space can store 2-6 pallets, with high density and faster access speed than drive-in.
3. Pallet Flow Racking
Features: Pallets are automatically moved forward by roller slides.
Applicable to: FIFO system, high turnover rate.
Advantages: High density + automatic first-in, first-out, very suitable for food, beverage, and pharmaceutical industries.
4. Mobile Racking
Features: The shelves can be moved along the track, and only one channel needs to be opened.
Applicable to: Low frequency of warehousing and high space utilization requirements.
Advantages: Extremely high space utilization (up to 90%), but high initial investment.
5. Double Deep Racking
Features: Two layers of pallets are placed on each row of shelves, and a telescopic forklift is required.
Applicable to: Bulk storage of similar products.
Advantages: Increase density but sacrifice some storage and access flexibility.
Advantages and disadvantages of High Density Racking:
Advantages:
Significantly improve storage density (up to 2-3 times that of ordinary racks)
Reduce unit storage costs
More suitable for warehouse management of large quantities and few SKUs
Disadvantages:
Limited access order (some systems do not support random access)
High equipment requirements (such as special forklifts and guide rails)
High cost (especially mobile and gravity systems)
Summary:
High density warehouse racking is one of the key solutions to improve warehouse efficiency. It is suitable for industries with high inventory turnover and expensive or limited storage space. If you are operating cold storage, food, medicine, manufacturing, etc., this type of racking can bring significant space and operating cost advantages.
