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;

---------------------- Page: 7 ----------------------
SIST EN 81-41:2011
EN 81-41:2010 (E)

 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).

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.
