Racking and Storage/Retrieval
FEM 9.832 - Basis of calculations for S/R machines, tolerances, deformations and clearances in automatic small parts warehouses (not silo design)
FEM 9.832-EN
Language version
This document applies to automatic small parts warehouses (not silo design) with S/R machines which travel on a floor mounted rail and are stabilized by an upper guide rail. The storage locations in the rack must be filled as evenly as possible (random storage).
The aim of this document is to show the relation of the individual system components in respect of tolerances and deformations. Permissible practical tolerances and deformations shall be listed for typical system solutions. The aim is that the values for individual system components will result in clearly defined levels of responsibility in the event of interface problems.
Due to the tolerances and deformations quantified in this document as well as the additional data for tolerances, wear and deformation of the S/R machine and the load make-up accessories, calculations for clearances and entry clearances must be made. The method used is described in section 7.
The aim of this document is to determine the admissible deformations and tolerances in order to optimise the factors relating to the economical dimensioning, manufacturing and assembly required for the safe functioning of the overall system.
Please note: this document applies to small parts / mini-load applications. For unit-load / pallet applications please refer to FEM 9.831-1
