BS EN 14502-1:2010EN 14502-1:2010 (E) 4 Introduction This European Standard deals with suspended basket for use in lifting operation of persons with machinery which is not designated for lifting of persons.

18、The use of such suspended basket is not covered by Machinery Directive 2006/42/EC but by the regulations which apply to the user. Care is necessary as the regulations which apply to the user are not the same in the various countries of the European Union. The national regulations are based on Direct

19、ive 2009/104/EC, which gives minimum requirements. The lifting of persons with machines not designed for that purpose is dealt with in annex II, article 3.1.2 of that directive, which prescribes: “Persons may be lifted only by means of work equipment and accessories provided for this purpose. Withou

20、t prejudice to Article 5 of Directive 89/391/EEC, exceptionally, work equipment which is not specifically designed for the purpose of lifting persons may be used to this effect, provided appropriate action has been taken to ensure safety in accordance with national legislation and/or practice laying

21、 down appropriate supervision. While workers are on work equipment designed for lifting loads the control position must be manned at all times. Persons being lifted must have reliable means of communication. In the event of danger, there must be reliable means of evacuating them.“ The national legis

22、lation and/or practice, referred to in the second paragraph of section 3.1.2, may set out the conditions under which such exceptional use is permitted, the measures that must be taken to ensure the safety of the operation and technical requirements for the equipment used. Such obligations apply to t

23、he users, but they also have implications for persons placing the equipment used for this purpose on the market in the country concerned since they must take account of the relevant legislation. This standard is a technical document to help the designer of suspended baskets used with machines not de

24、signed for lifting of persons. This standard was not prepared under a mandate given to CEN by the European Commission and cannot be considered as a means of conforming the Essential Requirements of the New Approach Machinery Directive 2006/42/EC.BS EN 14502-1:2010EN 14502-1:2010 (E) 5 1 Scope This E

25、uropean Standard applies to baskets suspended on cranes. This European Standard does not cover the controls for the movement of the basket. This European Standard is not applicable to: lifts for crane drivers; moveable cabins. This European Standard deals with all significant hazards, hazardous situ

26、ations and events relevant to suspended baskets, when used as intended and under conditions foreseen by the manufacturer (see Clause 4). The significant hazards covered by this document are identified in Clause 4. This European Standard is not applicable to suspended baskets which are manufactured b
