“How high can we stack?” This is the most central question in vertical storage. The answer is not a fixed number but a scientific measure determined by multiple factors.
1. Key Limiting Factors:
Warehouse Clear Height: The total stacking height must be at least 0.5 meters below the warehouse clear height to ensure a safe distance from fire safety systems, lighting, and roof structures.
Turf Grass Lawn Strength: The density, diameter, and weight of the roll determine its compressive resistance. Rolls with low density and large diameter have poorer resistance and require fewer stacking layers.
Pallet and Floor Load Capacity: The maximum load capacity of the warehouse floor and the pallets used must be known and never exceeded.
Forklift Operating Height: Stacking height must not exceed the safe operating range of your forklifts.
2. General Safe Stacking Layer Recommendations:
Standard Rolls: For most conventional turf grass lawn, when stacking directly on the floor or standard pallets, it is strongly recommended not to exceed 3 layers. This is an empirical value balancing safety, efficiency, and product protection.
Heavy/Large-Diameter Rolls: For exceptionally heavy or large-diameter products, stack only 1-2 layers.
Using Racking: Follow the racking manufacturer’s specified load limits per level. Often, more layers can be stored safely as the weight is borne by the racking structure.
3. Implementing Height Limit Management:
Install clear “Height Limit” lines and signs on warehouse columns or walls to provide a clear visual reminder for forklift operators.
