Introduction
The population of Europe is ageing and the prevalence of disability, including disability associated with the
ageing process, is increasing. Older people and people with disabilities at present are estimated to number
some 80 million people – a large and growing proportion of the European Union population. The changing
demography presents both opportunities and challenges for the Union. The economic, social and cultural
potential of older people and people with disabilities is underexploited at present. However there is a growing
recognition that society needs to exploit this potential for the economic and social benefit of society generally.
This is one of the reasons that led to this standard on vertical lifting platforms for people with impaired mobility
being one means to provide accessibility to buildings.
This standard is a type C standard as stated in EN ISO 12100 (all parts).
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
When provisions of this type C standard are different from those which are stated in type A and type 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.
The lifting platforms defined in this standard are suitable for type A and type B wheelchairs as defined
in EN 12183 and/or EN 12184.
Those items relevant to lifting platforms referenced within EN 81-70 have been included within this standard.
This standard does not only address the essential health and safety requirements of the Machinery Directive,
but additionally states minimum rules for the installation of lifting platforms into buildings/constructions. There
may be in some countries regulations for the construction of building etc. which cannot be ignored.
It is essential that minimum passageways conform to national building regulations and are not obstructed by
any open door or trap and/or any protection means provided for working areas outside of the enclosed liftway
where fitted according to the maintenance instructions.
Assumptions
With the aim of clarifying the intentions of the standard and avoiding doubts when applying it, the following
assumptions were made when producing it:
 Vertical lifting platforms are installed in both new and existing buildings;
 For existing buildings where space is not available, other dimensions may be considered. Local
building regulations should be observed;
 components without specific requirements are:
a) designed in accordance with the usual engineering practice and calculation codes, including all failure
modes;
b) of sound mechanical and electrical construction;
c) general hazards due to hydraulic, pneumatic, etc. equipment are dealt with according to relevant B level
standards for common use.
d) Materials known to be harmful materials, such as asbestos are not to be used as part of the machine;
 components are kept in good repair and working order, in accordance with the maintenance manual, so
that the required characteristics remain despite wear;
 by design of the load bearing elements, a safe operation of the machine is assured for loading ranging
from zero to, the dynamic operation maximum working load and static loading, to the maximum static
load;
 to ensure the safe functioning, the operating temperature range of the equipment has to take into account
the conditions of the place of use of the machinery, inside the maximum range of ambient temperature
between + 5 °C and + 40 °C. For very hot or cold environments extra requirements may be necessary.
 negotiations have been made between the customer and the manufacturer about:
 environmental conditions;
 civil engineering problems;
 other aspects related to the place of installation;
 the use and places of use of the machinery;
 the place of installation allows a safe use for the machine;
 any additional fire protection requirements;
 suitability for the user (see Annex B).
1 Scope
1.1 This European Standard deals with safety requirements for construction, manufacturing, installation,
maintenance and dismantling of electrically powered vertical lifting platforms affixed to a building structure
intended for use by persons with impaired mobility:
 travelling vertically between predefined levels along a guided path whose inclination to the vertical does
not exceed 15°;
 intended for use by persons with or without a wheelchair;
 supported or sustained by rack and pinion, wire ropes, chains, screw and nut, friction/traction between
wheels and the rail, guided chain, scissors mechanism or hydraulic jack (direct or indirect);
 with enclosed liftways;
 with a speed not greater than 0,15 m/s;
 with platforms where the carrier is not completely enclosed.
1.2 This standard deals with all significant hazards relevant to lifting platforms, when they are used as
intended and under the conditions foreseen by the manufacturer (see Clause 4).
1.3 This European Standard does not specify the additional requirements for:
 operation in severe conditions (e.g. extreme climates, strong magnetic fields);
 lightning protection;
 operation subject to special rules (e.g. potentially explosive atmospheres);
 handling of materials, the nature of which could lead to dangerous situations;
 vertical lifting platforms whose primary function is the transportation of goods;
 vertical lifting platforms whose carriers are completely enclosed;
 vertical lifting platforms prone to vandalism;
 hazards occurring during manufacture;
 earthquakes, flooding;
 fire fighting, evacuation and behaviour during a fire;
 noise and vibrations;
 the design of concrete, hardcore, timber or other foundation or building arrangement;
 the design of anchorage bolts to the supporting structure;
 type C wheelchairs as defined in EN 12183 and/or EN 12184.
 NOTE For the actual type of machinery, noise is not considered a significant nor relevant hazard.
1.4 This standard is not applicable to Vertical Lifting Platforms intended for use by persons with impaired
mobility which are manufactured before the date of its publication as an EN.

5 Safety requirements and/or protective measures
5.1 General requirements for lifting platforms
5.1.1 General
Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition,
the machine shall be designed according to the principles of EN ISO 12100 (all parts) for hazards relevant but
not significant, which are not dealt with in this document (e.g. sharp edges).
It shall be ensured that the dimensions specified in this standard are maintained, despite wear. Consideration
shall also be given to the need for protection against the effects of corrosion. The transmission of noise and
vibration to any surrounding walls and other supporting structures shall be minimised.
All materials shall be asbestos free.
5.1.2 Pattern of use
The mechanical design of the lifting platform shall take account of the frequency of usage to which it will be
subjected.
NOTE See Assumptions - negotiations.
5.1.3 Guarding
Components (for example gearing of the drive unit) shall be guarded to prevent the risk of personal injury.
Access panels shall be secured by means requiring the use of a tool or key for their release. Their fixing
systems shall remain attached to the guards or to the machinery when the guards are removed.
Guarding shall be designed and constructed in accordance with EN 953, EN ISO 13857 and EN 349.
5.1.4 Access for maintenance, repair and inspection
5.1.4.1 Working areas on the platform
5.1.4.1.1 General
Where machinery is to be maintained or inspected from the platform and if this work requires movement of the
platform or is likely to result in uncontrolled and unexpected platform movement, the following applies.
5.1.4.1.2 Any kind of uncontrolled and unexpected movement of the platform resulting from
maintenance/inspection that can be dangerous to persons carrying out maintenance/inspection work shall be
prevented by a mechanical device. Such device shall ensure a minimum 300 mm clear space between the
parts of the platform and rigid parts of the liftway where there is a risk of crushing. Monitoring of this device to
ensure that the device is in the passive position before normal operation, shall be by means of an electrical
safety device in accordance with 5.5.11.
5.1.4.1.3 Any necessary devices for emergency operation and for dynamic tests (such as brake tests,
traction tests, safety gear tests) shall be arranged so that they can be operated from outside of the enclosed
liftway.
5.1.4.2 Working areas under the platform
5.1.4.2.1 Where the lifting platform is to be maintained or inspected from underneath the platform the
following applies:
a) If a clear space of 500 mm minimum is not available under the platform when at its lowest position, a
manually positioned mechanical blocking device shall be provided to enable the platform to be held in a
raised position and to create a free distance of at least 500 mm between the floor of the working area and
the lowest parts of the platform. The device shall be able to stop the platform travelling downwards at
rated speed with maximum working load.
b) The blocking device shall be in position before entering the pit and shall be provided with an electric
safety device that detects the correct positioning of the mechanical blocking device and which will disable
the car and landing controls and enable any inspection control station. The function shall be clearly
marked with its intended purpose and position.
c) The opening of any door providing access to the pit shall be by use of a key, see 5.8.6, and prevent
normal operation of the lifting platform; visible information shall be available if the blocking device is not in
its active position. The return of the platform to normal service shall only be made by operation of a reset
device placed outside of the liftway and accessible to authorised persons only.
d) Where it is necessary to move the platform from the pit, an inspection control station according to 5.5.18
shall be available for use.
e) The floor of the pit shall be able to support the loads and forces (N) imposed to it and to support at any
position the mass of 2 persons, each counting for 1 000 N without permanent deformation.
5.1.4.2.2 When the platform is in the position according to 5.1.4.2.1 a), it shall be possible to leave the
working area easily and safely.
5.1.4.2.3 Any necessary devices for emergency operation and for dynamic tests, such as brake tests,
traction tests, safety gear tests, shall be arranged so that they can be operated from outside of the enclosed
liftway.
5.1.4.3 Working areas outside of the enclosed liftway
When the machinery is in the enclosed liftway and is intended to be maintained/inspected from outside of the
enclosed liftway, access to this equipment shall only be possible by a door/trap in conformity with 5.6.6.
5.1.4.4 Machinery outside of the enclosed liftway
5.1.4.4.1 If any part of machinery is located outside of the liftway e.g. control panel, drive machine, it
shall be located inside a cabinet.
5.1.4.4.2 The machinery cabinet shall consist of imperforate walls, floor, roof and door(s).
The door(s) shall:
a) not open towards the inside of the cabinet;
b) be provided with a key-operated lock;
c) be capable of being re-closed and re-locked without a key.
The only permissible openings are:
i) necessary openings for the functioning of the lift between the liftway and the machinery cabinet;
ii) vent openings for escape of gases and smoke in the event of fire. These openings when
accessible to non-authorised persons shall comply with the following requirements:
 protection according to EN ISO 13857:2008, Table 5, against contact with danger zones;
 IP2XD according to EN 60529.
5.1.5 Rated speed
The rated speed of the lifting platform shall not be greater than 0,15 m/s.
5.1.6 Rated load
The rated load shall be calculated at not less than 250 kg/m of the clear loading area, excluding handrails.
