8、i BSI 1 November 2004 Foreword This part of BS 5656 has been prepared by Subcommittee MHE/4/3/2. This part of BS 5656 paraphrases many of the requirements specified in all other relevant standards (listed in the bibliography). It indicates the information that should be exchanged between the interes

9、ted parties and the sequence of events from the preliminary planning stage to the putting into service. The most important issue to take into account during the selection and installation of escalators and moving walks is their safe use by all persons. General guidance is given in Clause 4 on the pr

10、ocedure to be adopted in obtaining an installation that is satisfactory from the aspects of operation, safety and maintenance. This clause also provides guidance on the exchange of information between the escalator and moving walk contractor and other trades in providing various service facilities,

11、and gives the overall chronological sequence. The building recommendations for the equipment have been brought together in Clause 5 because of their interest to the architect or other persons responsible for specifying the details of the building construction, which is not a prime responsibility of

12、the escalator and moving walk contractor. Clause 6 deals with sizing the installation to meet the traffic demands. Clause 7 gives guidance to architects and designers on the options permitted in BS EN 115 with regard to the dimensions for boarding and alighting areas. This clause also offers guidanc

13、e on equipment location and measures to reduce the risk to users. Clause 8 deals with electrical installation. Escalator and moving walk technology, duty categories and operating control systems are discussed in Clause 9. Although the main provision for vertical access for disabled people is a lift,

14、 it is recognized that many people with disabilities use escalators and moving walks. Therefore this part of BS 5656 takes their needs into account as far as possible and recommendations are given in Clause 10. Guidance on lift provision for disabled people is given in BS 5655-6. Attention is drawn

15、to the Supply of Machinery (Safety) Regulations 1992 1 in respect of procedures for contracting parties and in respect of CE marking. Attention is also drawn to the list of relevant statutory regulations given in Annex A. This part of BS 5656 should be read in conjunction with BS 7801, which gives r

16、ecommendations for safe working that are additional to the features recommended in this part of BS 5656 and are applicable when installing, examining, inspecting, testing, servicing, repairing, dismantling and demolishing permanent installations. As a code of practice, this part of BS 5656 takes the

17、 form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for

18、its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

It is applicable at the early stages of a pr

20、oject for architects, developers, building owners, building managers, building contractors, general and specialized engineering consultants and other interested parties. This part of BS 5656 does not give recommendations for existing installations. NOTE Although this part of BS 5656 does not give re

21、commendations for existing installations, it may be used as guidance when making alterations to such installations. 2 Normative references The following referenced documents are indispensable for the application of this document.

46、ification of escalator and moving walk equipment The classification of escalator or moving walk equipment is given in BS EN 115 as summarized below. The most commonly available nominal widths for escalators are 600 mm, 800 mm and 1 000 mm. The most commonly available rated speed is 0.50 m/s; other s

47、peeds available are 0.65 m/s and 0.75 m/s. The most commonly recommended angle of inclination is 30 , which is permitted for any rise. An angle of inclination of 35 is permitted for rises not exceeding 6 m and rated speeds not exceeding 0.5 m/s. The most commonly available nominal widths for moving

48、walks are 800 mm, 1 000 mm and 1 400 mm, but this is dependant on the inclination. These nominal widths are permitted up to an angle of inclination of 6 . Above 6 to the maximum permissible angle of inclination of 12 , the nominal width should not exceed 1 100 mm. 4.2 Enquiry or invitation to tender
