Rail dependent storage and retrieval equipment - Safety requirements for S/R machines

This document applies to all types of Storage and Retrieval (S/R) machines, restricted to the rails on which they travel within and outside the aisles for the storage and retrieval of unit loads and/or long goods such as bar materials and/or for order picking or similar duties. These machines shall embody lifting means along a mast and may include lateral handling facilities. Also included is the transfer equipment used to change between aisles. Control of machines may range from manual to fully automatic.
S/R-machine-related satellite vehicles according to definition 3.20 are included as a load-handling-device (LHD).
References in this standard to racking, buildings and systems only apply where it is necessary to assess the hazards and risks at their interfaces with S/R machines.
This document deals with all significant hazards relevant to rail dependent storage and retrieval equipment, when they are used under the conditions intended by the manufacturer including reasonably foreseeable misuse (see Annex F "List of significant hazards")).
This document applies to machines and equipment that are manufactured after the date of issue of this document.
Illustrations of examples of machines and transfer equipment to which this standard applies are shown in Annex A.
Safety requirements and/or measures in this standard apply to equipment used under indoor conditions. However, additional risk assessments and safety measures need to be considered for uses in severe conditions, e.g. extremely high temperatures, loads, the nature of which could lead to a dangerous situation (e.g. especially brittle loads, explosives), earthquake effects and also contact with foodstuff.
This document also deals with the technical requirements for electromagnetic compatibility (EMC).

European foreword

This document (prEN 528:2019) has been prepared by Technical Committee CEN/TC 149 “Power-

operated warehouse equipment”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.
This document supersedes EN 528:2008.
The main changes compared to the previous edition EN 528:2008 are as follows:

— clearer / more understandable Annex C dealing with preventing access to dangerous movements

across the load entry/exit points;

— Annex ZA has been updated by introducing the generic template for Annex ZA amended in

accordance with decision of EU commission;

— revision and adaption of Annex B Performance level according to EN ISO 13849-1:2015;

— the scope has been stated more precisely;

— more readable and clearer text in standard due to avoidness of separate chapters for automatic and

manual machine;
— amendment or rather change of the following definitions (3):

— on-board control position (3.4), permanent on-board control position (3.5), powered access

cabin (3.6), climb assistance system (3.7), rated speed (3.13), normal operation (3.19), satellite

vehicle (3.20), load entry / exit points (3.21), working place (3.22), pick and deposit (P&D)

station (3.24), restricted area (3.25), danger area (3.27);
— speed limitation (4.9.4) has been updated and been stated more precisely;

— an additional braking system is required if the end stops (e.g. buffers) are designed for a speed less

than 70 % of the rated speed (4.5.1.3);

— where a powered access cabin is provided, it shall comply with the requirements for control positions

(4.9.7.1);

— for detachable ladders on the lift mast a fall arrest system is required from a height of 3m onwards

(4.9.7);

— safety gear required for lifting carriages, that are designed to carry person(s) (4.4.4.1);

— the ratio of the minimum breaking force to the maximum static force for all types of suspension

elements to the lifting of persons has been reduced from 10 to 8 (4.4.5);

— requirements for additional person(s) on the lifting carriage has been stated more precisely (4.9.2.1);
