Meaning
Specifications for steel static storage systems establish technical tolerances, deformations, and clearances for pallet racking in industrial environments. Compliance with en 15620 governs how vertical uprights deflect under maximum load and dictates the horizontal gaps required for automated handling equipment to function without collision. It defines the structural limits for installation geometry to maintain the safety of warehouse operations when automated cranes interact with high density racking.
Operational Tolerance
Manufacturers rely on these provisions to ensure that the vertical alignment of rack uprights remains within defined limits under loaded and unloaded conditions. Engineers utilize en 15620 to calculate the necessary clearances between the load unit and the storage structure to prevent mechanical interference during retrieval cycles. Precise adherence to these spatial constraints reduces the probability of crane strikes in aisles where high speed automated systems operate.
Structural performance depends upon the stiffness of the components and the accuracy of the final assembly.
Safety Verification
Regular audits of rack plumb and deflection verify that installations continue to meet the original design parameters over the service life of the facility. Personnel use calibrated measurement tools to check that floor levelness and upright verticality align with the prescriptive limits described in en 15620. Should measurements deviate from these thresholds, the operator must recalibrate the automated storage retrieval machine or reinforce the racking framework to avoid catastrophic failure.
Installation Compliance
Successful implementation of rack systems requires clear communication between the steel fabricator and the warehouse integrator regarding site ground conditions. If the slab deflection exceeds the levels permitted by en 15620, the racking structure loses its certification for automated use regardless of the precision of the individual rack components. Correct floor preparation is therefore the primary factor in determining whether a storage system achieves its theoretical throughput capacity.
A compliant installation minimizes the risk of structural damage while ensuring that material handling equipment maintains its travel velocity throughout the storage system.
