Standards manual pallet racks
Today, almost every country has its own standards of operation of pallet racking and shelving equipment manufacturers association (for example, in the UK it is SEMA). More than 10 years ago, the Federation of European manufacturers (shelf equipment department) recommended the use of standards for the design and operation of the racks. Pallet racking FEM 10.2.02. – Standard design and FEM 10.3.01 – tolerance components.
In Russia, production and operation of pallet racks regulate the following standards:
– GOST 14757_81 Ctellazhi collapsible. Types, basic parameters and dimensions (with a change in N 1, 2) – Resolution of the State Standard of the USSR from 10.07.1981 N 3323
– Standard of 10.07.1981 N 14757-81;
– GOST 16140_77 Shelves collapsible. Specifications of the USSR State Standard Resolution dated 28.10.1977 N 2528 GOST from 28.10.1977 N 16140-77;
– GOST 28766_90 Racks. Bases of calculation – Resolution of the State Standard of the USSR from 03.12.1990 N 3007 GOST from 03.12.1990 N 28766-90.
However, the listed standards do not apply to special purpose racks. This means that the production and supply of pallet racks can be carried out on the basis of its own technical conditions, without complying with the requirements of the above regulations.
Here is the GOST 16140-77 for the production and operation of the collapsible shelves.
