This European Standard deals with the technical requirements to minimize the specific railway hazards of self propelled road-rail machines-henceforward referred to as machines-and associated equipment, which can arise during the commissioning, the operation and the maintenance of machines when carried out in accordance with the specification given by the manufacturer or his authorised representative. Part 1 of EN 15746 defines requirements for approval of the machine by an authorised body; Part 2 defines requirements for the machine to be declared conformant by the manufacturer, except in the case of machines classified under Annex 4 of the Machinery Directive, which require a conformity check in conjunction with a notified body. Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilizing other than adhesion between the rail and rail wheels and underground infrastructures.This European Standard is also applicable for machines and associated equipment that in working configuration are partly supported on the ballast or the formation.This European Standard does not apply to the following: the requirements for quality of the work or performance of the machine; the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the infrastructure manager; running and working whilst not on rails; separate machines temporarily mounted on machines and associated equipment; demountable machines as defined in 3.2; trailers as defined in 3.3, including road-rail trailers.This European Standard does not establish the additional requirements for the following: operation subject to special rules, e. g. potentially explosive atmospheres; hazards due to natural causes, e. g. earthquake, lightning, flooding; working methods; operation in severe working conditions requiring special measures, e. g. work in tunnels or in cuttings, extreme environmental conditions such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields; hazards due to errors in software; hazards occurring when used to handle suspended loads which may swing freely. Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex G.This European Standard applies to all machines which are ordered one year after the publication date by CEN of this European Standard.
La présente norme s'applique aux coupeuses à cha?ne et à sangle, destinées à être utilisées dans des carrières à ciel ouvert ou souterraines. Les coupeuses à cha?ne et à sangle sont utilisées pour découper le marbre, le granite et d'autres pierres libres ou à la surface. Ces machines peuvent être fixes ou peuvent se déplacer sur des rails lors de l'exploitation.La présente norme traite des coupeuses avec moteur électrique principal et équipées d'une tête de sciage principale. La présente Norme européenne couvre seulement les machines pour la découpe à plat (sur un axe) et ne couvre pas les difficultés provenant de la géomorphologie de la pierre à découper.La présente norme ne couvre pas le phénomène dangereux significatif du bruit.La présente norme traite tous les phénomènes, situations et événements dangereux significatifs relatifs aux coupeuses à cha?ne et à sangle, lorsqu'elles sont utilisées dans des conditions normales et dans des conditions de mauvaise utilisation raisonnablement prévisibles par le constructeur (voir Article 4). La présente Norme européenne traite des phénomènes dangereux pendant le transport, la mise en service, l'utilisation et la maintenance.La présente Norme européenne ne traite pas : de l'exploitation dans des conditions ambiantes extrêmes (au-delà des limites définies dans l'EN 60204-1) ; de l'exploitation dans des atmosphères potentiellement explosibles.Le présent document n'est pas applicable aux machines fabriquées avant sa date de publication comme EN.
This Part 6 of EN 1993 provides design rules for the structural design of runway beams and other crane supporting structures.The provisions given in Part 6 supplement, modify or supersede the equivalent provisions given in EN 1993-1.
This standard applies to chain- or belt-slotting machines to be used in open or underground quarries. Chain-or belt-slotting machines are used for cutting marble, granite and other stones loose or at the face. They canbe stationary or can be moved on rails during work.This standard deals with slotting machines with electric main motor and equipped with one main sawing head.This European Standard covers only machines for plain cutting (with one axis) and does not cover the difficul-ties arising from the geomorphology of the stone to be cut.This standard does not deal with noise as a significant hazard.This standard deals with all significant hazards, hazardous situations and events relevant to chain- and belt-slotting machines, when they are used as intended and under conditions of misuse which are reasonablyforeseeable by the manufacturer (see Clause 4). This European Standard deals with the hazards duringtransport, commissioning, use and maintenance.This European Standard does not deal with:-- operation under extreme ambient conditions (outside the limits defined in EN 60204-1);-- operation in a potentially explosive atmosphere.This document is not applicable to machines which are manufactured before the date of its publication as EN.
This European Standard deals with the technical requirements to minimize the specific railway hazards of trailers and associated equipment, which can arise during the commissioning, the operation and the maintenance of trailers when carried out in accordance with the specification given by the manufacturer or his authorized representative. This European Standard applies to trailers that are not intended to interact with signalling and control systems.
This European guidance document provides guidance on the selection of existing building hardware for manually and power operated pedestrian doors and associated products whose integration into the design of buildings will make them more safe, secure and convenient for the occupants inclusive of children, elderly and disabled people to use (\"design for all\"). Although it is intended for people with reduced physical and sensorial capabilities, it may not cover all specific individual needs. For example, it may not cover all needs of blind people or those not able to move unassisted.
This European Standard applies to transportable masonry and stone cutting-off machines stationary during work, principally used on job site building construction for cutting-off stones, other mineral construction materials and composite materials having at least one supporting surface. The power for the tool rotation is supplied by electrical or internal combustion prime motor. This European Standard deals with all significant hazards pertinent to masonry and stone cutting-off machines for job site (see clause 4), when they are usedas intended and under the conditions foreseen by the manufacturer. This European Standard specifies theappropriate technical measures to eliminate or reduce risks arising from the significant hazards.These machines are designed for use with rotating diamond cutting-off wheels with a continuous rim and/or segmented rim.This European Standard does not apply to:-metal cutting-off machines;-wood and timber sawing machines;-machines with a feed or descent mechanism other than manual, or with a pedal;-mobile machines on a trolley travelling on the ground;-hand-held portable grinding and cutting-off machines;-hand-held portable grinding and cutting-off machines mounted on a support to be used in a fixed position.This European Standard does not cover the operation of transportable masonry and stone cutting-offmachines in potential explosive atmospheres.This European Standard covers electrical hazards making reference to relevant European Standards (see5.2).Those hazards that are relevant for all mechanical, electrical, hydraulic, pneumatic and other equipment of machinery and that are dealt with in standards for common use are not covered by this European Standard.Reference to pertinent standards of this kind is made where such standards are applicable and so farnecessary.In this standard, the masonry and stone cutting-off machines for job site construction are called: \"cutting-off machines\" or \"machines\", and cutting-off wheels are also called: \"tools“.This standard applies primarily to the machines which are manufactured after the date of approval of the standard by CEN.
