然而，在天轨和地轨的安装公差符合《Basis of calculations for storage and retrieval machines - Tolerances, deformations and clearances in the storage systems Part 1: General, Single deep and Double deep Beam Pallet racking》FEM 9.831-1或《Basis of calculations for S/R machines, tolerances, deformations and clearances in automatic small parts warehouses(not silo design)》FEM 9.832、天轨侧导轮的装配质量和磨损限制符合堆垛机供应商的技术规范的情况下，可以假定货架结构的阻尼性足以防止存储单元在振动下发生移动。因此保证货架的安装精度与质量，是实现设计功能的基础前提。
