然而,在天軌和地軌的安裝公差符合《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、天軌側導輪的裝配質量和磨損限制符合堆垛機供應商的技術規(guī)范的情況下,可以假定貨架結構的阻尼性足以防止存儲單元在振動下發(fā)生移動。因此保證貨架的安裝精度與質量,是實現設計功能的基礎前提。
