Introduction
This standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this standard.
For machines designed and built according to the specifications of this Type C Standard the following applies:
"When provisions of this type C standard are different from those which are stated in type A or B standards,
the provisions of this type C standard take precedence over the provisions of the other standards for
machines that have been designed and built according to the provisions of this type C standard."
When this standard was prepared it was assumed that:
 only trained staff would operate, repair or maintain the machine;
 components without special requirements are
1) sized in accordance with good engineering practice and methods of calculation including all types of
failure;
2) correctly constructed mechanically and electrically;
3) made of materials of adequate loading capacity and of suitable quality;
4) made of materials that are fit for that purpose.
 components are kept in a good repair and operating condition so that the required characteristics can be
maintained in spite of wear and tear;
 sizing of load bearing parts ensures safe operation of the machine in a loading range from 0 % to 100 %
of the nominal capacity and during testing conditions if applicable;
 details of particular conditions of use and the installation site are agreed between user and manufacturer;
 working area is adequately illuminated;
 installation site permits safe operation of the machine.
1 Scope
1.1 This European Standard deals with the safety requirements for the following types of power-operated
storage equipment:
 storage carousels;
 storage lifts;
 mobile shelving, pallet racking and cantilever racking
with the objective of eliminating or minimising the hazards described in Clause 4. These hazards can arise
during installation, starting up, operation, maintenance, testing and dismantling of the equipment.
1.2 It is essential that the safety requirements and/or measures taken in this standard be applied to storage
equipment which operates indoors. Under difficult conditions, it is essential that additional hazard analysis and
safety measures be taken into account, e. g. outdoor conditions, freezer applications, high temperatures,
corrosive environment, strong magnetic fields, risk of explosive atmosphere, radioactive conditions, storage
goods which due to their nature could generate hazardous situations (e. g. molten metal, acids/alkalis, fragile
goods or explosives), effects of earthquakes and also contact with food.
1.3 Examples of power-operated storage equipment to which this standard applies are shown in Annex A.
1.4 With regard to buildings and parts of buildings, this standard applies only insofar that an assessment
regarding hazards and risks in connection with interfaces to the storage equipment is carried out.
1.5 Storage equipment whose only power source is directly used human labour or gravity are excluded
from the scope of application of this standard.
1.6 Power-operated storage equipment or parts of them do not fall under the regulations for passenger lifts.
They are intended to handle and store goods. They are not intended to transport passengers under normal
use (except for maintenance) and therefore not considered to be lifts (elevators).
1.7 This standard does not take hazards into account, which arise from noisy environments or
environments subject to electromagnetic interference outside the range quoted in EN 61000-6-2.

5 Safety requirements and protective measures
5.1 General requirements
Storage equipment shall conform to the safety requirements and/or protective measures of this section and
also to the requirements of EN ISO 12100-1 and EN ISO 12100-2 concerning relevant but not significant
hazards, which are not dealt with in this standard.
Storage equipment and their accessories shall be suitable for operation in the intended condition of use in the
working environment for which they have been designed.
Care shall be taken to review the safety aspects of the interfaces with other storage products such as mobile
and static racking or pedestrian access areas.
5.2 Mechanical hazards
5.2.1 Design and Installation
5.2.1.1 General
Storage equipment shall be designed and installed in such a way that it is able to support the load of the
storage goods safely when used in a correct manner.
The stability and load carrying capacity shall be sufficient for the operating loads and be established through
calculations of the carrying capacity of the load bearing elements or via static load tests.
The intersection between single components shall be co-ordinated (e. g.: connecting forces, -moments and -
stiffness's, as well as electrical, pneumatic and hydraulic connections).
5.2.1.2 Installation
Storage equipment and their accessories shall be constructed so that they can be safely installed. If
necessary anchorage points for safety harnesses shall be provided.
Storage equipment shall be aligned vertically to the tolerances specified by the designer and as laid down in
the installation instructions.
The maximum deviation from the vertical shall not exceed 1/350 of the height.
5.2.1.3 Stability
The stability factor in the serviceability state (normal operation) with regard to tipping due to inertia forces or
due to horizontal placement loads considered separately shall be at least 2.0:
Static moment
Stability factor = ≥ 2,0
Tippingmoment
To cater for an accidental stop in mobile storage equipment the designer shall base his calculation on an
assumed stopping distance of 15 mm. For this situation the stability factor is allowed to be ≥ 1,1.
Established proof of stability shall also be provided for the partially loaded condition.
Pattern loading to check the tipping stability in case of mobile storage equipment:
 only top most storage level is loaded, single sided;
 all storage levels are loaded, single sided, with the exception of the level directly supported by the base of
the mobile equipment.
Pattern loading to check the tipping stability in case of vertical carousels:
 only top most storage level is loaded.
For other products stability shall be checked in the worst possible loading condition.
5.2.1.4 Safeguarding against failure of racking
The basis of design for steel bases and rack structures will be in accordance with EN 1993-1-1 and EN 1993-
1-3 as far as it applies to these structures.
Inertia forces due to accidental stop (stopping distance max. 15 mm) have to be considered with a load
factor: 1,1.
5.2.1.5 Safeguarding against failure of suspension and drive elements of carousels and storage lifts
The storage equipment manufacturer shall have a certificate on chains/ropes/belts (or other) showing the
minimum design breaking load of chains/ropes/belts (or other) and refer to that certificate for each purchase.
To minimise calculation and validation effort (e. g. wear, and tear, contamination, shock loading during the
lifetime of the equipment) it is permitted to use the following simplified methods:
a) Vertical carousels
The suspension chains shall be designed in accordance with ISO 10823 to withstand, without breaking,
7 times the maximum static force or 5 times the maximum dynamic force occurring during fully loaded
operation. For the calculation of the maximum break load is the sum of the load fixed on maximum length of
vertical chain segments located over each other mandatory (see Annex E).
b) Horizontal carousels
No specific condition is required if failure of the drive elements results in a fail-safe condition, otherwise a)
applies.
c) Storage lifts
The suspension chains, ropes, belts and other suspension elements shall be designed to withstand, without
breaking, 7 times the maximum static force or 5 times the maximum dynamic load force occurring during fully
loaded operation. The requirements for rack and pinion systems are given in Annex D. If personnel are being
transported see also 5.2.3.5.
Storage lifts with a working load limit of 1 000 kg or more shall be provided with an overload protection.
5.2.1.6 Actions (Loads and forces)
When verifying the level of safety with regard to stability and failure, the following possible combination of
actions shall be considered:
 sum of self-weights;
 sum of specified imposed loads (e. g. design values for shelf loads and weight of load units);
 placement loads, as a consequence of the method of manual or mechanical operating the storage
equipment;
 inertia forces due to normal stop and emergency stop.
The initial non-verticality imperfection may not be regarded as a loading, but shall be treated as an initial
property of the structure. Nevertheless it is allowed to take the non-verticality into account as an equivalent
horizontal load at each storage level.
This imperfection shall be taken into account in the longitudinal as well as in the transversal direction, but not
simultaneously.
5.2.1.7 Locks against falling out and/or down
Components of storage equipment shall be designed or secured in such a way that they cannot fall out or
down (e. g. clipped or hooked-in components, drawers).
5.2.1.8 Deflection
The following deflection limits shall be considered for the maximum permissible imposed load, if no specific
requirements have to be fulfilled:
 steel: span/200;
 timber or wood-based: span/150.
but taking into account the influence of the load duration according to EN 12369-1.
Finaldeflection= (shorttermdeflection)× (1+k )
def
where
k = load duration factor depending on material type and load duration classification
def
5.2.1.9 Safeguarding hazardous locations
Dangerous locations (e. g. crushing, drawing-in, shearing locations) on storage equipment shall be guarded,
where safety distances according to EN 294 and EN 811 respectively the minimum distances to avoid
crushing according to EN 349 are not maintained.
If guards are used, they shall be fixed in a reliable manner and of adequate mechanical strength. It shall only
be possible to remove them with a tool or they shall be interlocked with the drive.
As far as contactless safety equipment is used, it shall conform to safety category 2 (testing) in accordance
with EN ISO 13849-1 respectively Type 2 according to EN 61496-1.
In order to prevent unintended dangerous movements during maintenance there shall be available fixing
devices designed to suit the machine which can be securely attached. The required parts shall be delivered
with the machinery.
5.2.1.10 Manually operated drive
Storage equipment which is designed for optional hand operation shall be so designed that the power
operated drive is not able to activate the manually operated drive. This applies also to emergency operation.
5.2.1.11 Main switch
Storage equipment shall be equipped with a main switch.
It shall be possible to secure main switches in the "Off" position against unintentional and unauthorised
operation.
Instead of a main switch, a plug-in connection is permissible up to a nominal current of 16 A and total motor
output up to 3 kW.
5.2.1.12 Tripbars
Tripbars shall work over the full length. Limit switches which are operated by the tripbars shall be of a positive
operated type and interlocked with the drive so that when they are operated the dangerous movement is
safely stopped. Automatic re-starting shall be prevented.
NOTE See EN 1760-2 and EN 50047 for design shapes of position switches.
5.2.2 Carousels
5.2.2.1 Openings
5.2.2.1.1 General
To safeguard the operating personnel against dangerous movement of load bearing devices of carousels the
following protective measures are necessary.
5.2.2.1.2 Opening for picking
Dangerous areas and shearing points shall be protected e. g. by trip bars, contactless safety devices.
5.2.2.1.3 Carousels with more than one access opening
Carousels with more than one access opening shall be fitted with electrically interlocked doors or monitoring
elements so that only one access opening can be used at a time. Monitoring elements can be motion sensors,
switching mats, light barriers or similar devices.
The monitoring and interlocking elements shall be in compliance with EN ISO 13849-1 as defined after the risk
analysis for the whole machine.
5.2.2.1.4 Cladding
Covers on Carousels which have to be opened by the operator when dealing with operating faults shall be
electrically interlocked with the drive.
5.2.2.2 Protection
5.2.2.2.1 Safe vertical and horizontal movements
If storage accessories (e. g. drawers, bins, trays) are not in driving position, the movement shall be impossible.
5.2.2.2.2 Protection against uncontrolled forward and backward motion through uneven loading
Generally vertical carousels shall be designed so that unintentional forward and backward movement is
prevented effectively, when the highest degree of uneven loading distribution occurs (load difference between
front and rear loading planes). For storage units of more than 3 tonnes load capacity devices are permitted
which indicate optically or acoustically when the uneven loading distribution has reached the permissible limit
and which prevent starting up or interrupt the moving operation in the critical direction when the limit has been
exceeded. The correct sequence of loading and unloading shall be described in the operating manual.
For carousels with storage goods of almost the same shape and a complete view into the unit (e. g. carpet
display units), it is sufficient to design the drive for the highest permitted degree of uneven loading distribution
and to provide definite instructions in the operating manual.
5.2.2.2.3 Protection against items falling off
Carousels shall be provided with safety measures against items falling off. Panelling, covering and protection
devices shall be adequately dimensioned and secured. Protective measures shall not generate new
dangerous locations.
5.2.3 Storage lifts
5.2.3.1 Openings
5.2.3.1.1 Openings for picking
Areas where there is a possibility of entanglement or shearing shall be protected either by interlocked doors or
light curtains at the outer rim of the picking opening or by means of light curtains at another position together
with mechanical design which prevents the occurrence.
EXAMPLE The danger of entanglement between a load bearing device and picking opening is avoided, if the picking
opening is designed smooth and when the distance between load bearing equipment and picking opening is either less
than 5 mm or more than 50 mm.
A warning label has to be mounted durable and easy visible at the opening with clear declarations of the risks.
It shall be ensured that a load carrier e. g. storage container which is being dealt with at an access opening
cannot be called up from a different access opening.
5.2.3.1.2 Opening for maintenance
Access openings for maintenance if provided shall be guarded in accordance with EN 953. They shall only be
opened with a special tool or shall be interlocked with the electrical drive.
5.2.3.2 Protection against items falling off
Storage lifts shall be provided with safety measures against falling items. Panelling, covering and protection
devices shall be adequately secured. Protective measures shall not generate new dangerous locations.
5.2.3.3 Cladding
Covers on storage lifts which have to be opened by the operator when dealing with operating faults shall be
interlocked with the drive.
5.2.3.4 Anti-drop system
An anti-drop device for the use of a fall arrester shall be fitted in the storage equipment and extending to the
full height of the equipment.
5.2.3.5 Transporting people during installation, maintenance and fault repair of storage lifts
If the machine is designed for service personnel to ride or stand on the lifting platform for installations,
maintenance and repair, the following design requirements shall be met:
 static load factor of 10 shall be applied for personnel, tools and self weight of platform;
 active overload protection system while transporting people shall be provided;
 independent working safety gear and overspeed governor in accordance with EN 81-1;
 "travelling-with" hold-to-run two hand controller is required which shall:
1) comply with category 2 of EN ISO 13849-1;
2) also be capable of providing an acoustic signal;
3) inactivate the main control function except the emergency stop;
4) prevent horizontal movements of load carriers towards the storage place.
 travel speed under maintenance conditions shall not exceed 0,05 m/s; if the platform is equipped with
guards (minimum height: 900 mm, minimum distance of the handrail to fixed points of the lift: 100 mm) a
maximum speed of 0,15 m/s is allowed;
 platform for transporting the person shall be of a non-slip design and be fitted with raised sides at least 50
mm high on all sides;
 survival space of 1,5 m height shall be provided;
 means shall be provided to anchor the person being transported against a fall. This shall be ensured by
anchoring points on the platform;
 control equipment on the platform shall have priority over all other control equipment.
5.2.4 Mobile shelving, pallet racking and cantilever racking
5.2.4.1 Floor clearances
In order to avoid injury to feet, the distance between the bottom edges of mobile storage equipment (also of
safety devices) and the floor shall not exceed 15 mm for:
 handloaded mobile shelvin
