1 Scope
1.1 This European Standard deals with safety requirements for construction, manufacturing, installation, maintenance and dismanting 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); 一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;
3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following apply. 3.1 balancing weight mass which saves energy by balancing all/or part of the mass of the unloaded lifting platform 3.2 competent person person, suitably trained and qualified by knowledge and practical experience, and provided with the necessary instructions to enable the required work to be carried out safely 3.3 down direction valve electrically controlled valve in a hydraulic circuit for controlling the descent of the lifting platform 3.4 drive system system that causes the lifting platform to move under power input 3.5 drive unit unit, including the motor, that drives and stops the lifting platform 3.6 electric safety chain total of the electric safety devices, which can either be switches or safety circuits, connected in series with each other 3.7 electrical safety circuit electrical or electronic circuit with an equivalent degree of safety to a switch containing electrical safety contacts 3.8 electrical safety contact contact in which the separation of the circuit breaking elements is made by positive means 3.9 electrical safety device either an electrical switch incorporating one or more electrical safety contacts, or a safety circuit 3.10 enclosed liftway space that is fully bounded by the bottom of the pit and a solid enclosure (but not necessarily a ceiling) and landing doors 3.11 existing building building which has been previously occupied and constructed prior to the requirement for a lifting platform 3.12 final limit device electrical safety device operated by the lifting platform in the event of over-travel of the normal operation stop 3.13 full load pressure static pressure exerted on the piping directly connected to the jack, the platform with the rated load being at rest at the highest landing level 3.14 guide rail rigid components that provide guiding for the platform 3.15 guided chain chain, which can be either fixed or moving, and which is completely guided over its entire length such that it can transmit a load either in thrust or tension 3.16 guided chain system platform supported, raised and lowered by means of one or more chain transmission units 3.17 impaired mobility difficulty in using stairs because of impairment NOTE Examples of persons with impaired mobility include, but are not restricted to: wheelchair users, persons with pushchair, persons with walking difficulties, persons using walking aids, carers for persons with impaired mobility and/or children with impaired mobility, and elderly persons.
