It was prepared by Technical Committee MHE/4, Lifts, hoists andescalators. A list of organizations represented on this committee can beobtained on request to
20、 its secretary.SupersessionThis British Standard supersedes BS 6440:1999, which is withdrawn.Relationship with other publicationsRelated standards for similar devices for use by persons with impaired mobilityare BS EN 81-40, BS EN 81-41 and BS 5900 (the latter relates to private dwellingsonly).Those
21、 items relevant to lifting platforms referenced within BS EN 81-70 havebeen included within this edition of BS 6440.Information about this documentThis is a full revision of the standard, and introduces the following principalchanges: change from a code of practice to a specification; changes to mee
22、t the essential health and safety requirements of MachineryDirective 2006/42/EC 1 as enacted as the Supply of Machinery (Safety)Regulations 2008 2.BS 6440:1999 applied to lifting platforms with fully and partially enclosedliftways travelling over stated distances. A new standard, BS EN 81-41, applie
23、s tolifting platforms with enclosed liftways. However, BS EN 81-41 does not specifyrequirements for lifting platforms with a non-enclosed liftway, which arecommon on the UK market. The revised BS 6440 specifies requirements forlifting platforms with non-enclosed and partially enclosed liftways.Use o

Itsrequirements are expressed in sentences in which the principal auxil
26、iary verb is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of acontract. Users are responsib

28、ditionallyspecifies minimum requirements for the provision of lifting platforms inbuildings/constructions.It is assumed that the lifting platform operates in an ambient temperature inthe range 5 C to 40 C. For temperatures outside this range, additionalmeasures might be necessary.This British Standa
29、rd does not specify requirements for: severe conditions (e.g. extreme climates, strong magnetic fields); lightning protection; potentially explosive atmospheres; the handling of materials, the nature of which could lead to dangeroussituations; lifting platforms of which the primary function is the t
30、ransportation ofgoods; lifting platforms prone to vandalism; earthquakes or flooding; fire-fighting, evacuation and behaviour during a fire; vibrations; the design of concrete, hardcore, timber or other foundation or buildingarrangement; the design of anchorage bolts to the supporting structure; typ
31、e C wheelchairs as defined in BS EN 12183 and/or BS EN 12184; balancing weights or counterweights.This revision of BS 6440 deals with all significant hazards relevant to liftingplatforms, when they are used as intended and under the conditions foreseenby the manufacturer. A list of significant hazar
32、ds is given in Annex A.In order to determine the specific characteristics of the lifting platform, at leastthe following issues need to be discussed between the supplier and the specifier: environmental conditions; civil engineering considerations; other aspects related to the place of installation,
33、 including safe use of thelifting platform; the use and places of use of the machinery; fire protection requirements; suitability for the user.Annex B gives information on issues which specifiers are expected to discusswith the supplier in order to select and specify a suitable powered liftingplatfo
34、rm.BRITISH STANDARD BS 6440:2011 BSI 2011 1It is assumed that a powered lifting platform conforming to this standard is forthe use of persons either: capable of using the lifting platform safely and unaided, either after havingbeen fully instructed in its use, or having observed clear and simpleinst
35、ructions permanently displayed on the equipment; or if not capable of safe unaided use of the lifting platform, transported underthe care of a fully instructed able-bodied accompanying person for whomadditional control facilities can be provided if required. Recommendationsfor specially adapted cont
36、rol devices are given in Annex C.1 ScopeThis British Standard specifies requirements for the design, manufacture,installation, commissioning, testing, maintenance and dismantling of newpermanently installed electrically powered vertical lifting platforms with thefollowing characteristics: travelling
37、 vertically between predefined levels along a guided path wherethe inclination to the vertical does not exceed 15; supported or sustained by wire ropes, chains, rack and pinion, hydrauliccylinder (direct or indirect), screw and nut or scissors mechanisms; having non-enclosed or partially enclosed li
38、ftways; having non-enclosed or partially enclosed carriers; having a rated speed that is not greater than 0.15 m/s; having a travel distance that is not greater than 3.0 m; sized for use with type A or type B wheelchairs conforming to BS EN 12183and/or BS EN 12184.It is applicable to lifting platfor
39、ms that are intended primarily for the transportof persons with impaired mobility, with or without a wheelchair.NOTE 1 The lifting platforms specified in this standard can be used in domestic ornon-domestic premises, and can be installed indoors or outdoors. Their installation insome premises might
40、not be practicable.NOTE 2 Although this British Standard is applicable to new lifting platforms, it canalso be used as guidance for the refurbishment and re-installation of existing liftingplatforms.2 Normative referencesThe following referenced documents may be used in the application of thisBritis
