This British Standard, prepared under the author
21、ity of the Mechanical Engineering Industry Standards Committee, revises, and supersedes, the I958 edition, which was entitled BS 2655, Electric lifts . 2. The new title reflects the extension of the scope of this British Standard. Amendments to Parts 1, 2 and 3 of this standard have been published,
22、and im- plement the change in title, The revised Part 1 and additional new parts will be published separately and, together with Parts 2 and 3, are as follows. Part 1. General requirements for electric, hydraulic and handyowered lifts. This part is basically a revision of the 1958 edition of BS 2655
23、 Part 1, without the building requirements and list of definitions, and extended to cover the engineering and safety requirements for new hydraulic and hand-powered lifts as well as for new electric lifts. Part 2. Single-speed polyphase induction motors for driving lifts. This part covers the type o
24、f electric motor specially designed for driving Iifts. It should be used in conjunction with BS 261 3T and gives additional requirements including the class of lift rating and special limits of temperature rise. AS amended Part 3. Arrangements of standard electric lifts. This part gives standard dim
25、en- sions for lift wells and machine rooms in relation to lift capacity and platform Oc., 1974 sizes, for seven classes of lifts. Part 4. General requirements jor escalators and passenger conveyors. This part specifies engineering and safety requirements for escalators and passenger con- veyors. The
26、 latter may be described as machines in which the passenger carrying surfaces remain parallel to the direction of motion and are uninterrupted. Part 5. General requirements for paternosters. This part specifies engineering and safety requirements for paternosters which may be described as machines t
27、BS 261 3, The electrical performance of rotating electrical machinery. 6 t .- where series of cars are continuously running in closed loops, and are charac- terized by the car floors remaining substantially horizontal when the direction of motion is reversed at the extremities of car travel. Part 6.
28、 Building construction requirements. This part specifies structural and fre resistance requirements for the equipment covered by Parts 1,4 and 5. Part 7. Testing and inspection. This part specifies tests, examination and certification of new and modified equipment covered by Parts 1,4 and 5. Part 8.
29、 Modernization or reconstruction of lift. This part specifies engineering and safety requirements. Part 9. Definitions. This part gives definitions of terms used in the remainder of the standard. Part 10. General reqfciuements for guarding. This part specifies requirements for the guarding of moving
30、 parts and protection against hazards from electrical equipment. It relates to equipment covered in Parts 1, 4 and 5. CP 407 : 1972. British Standard Code of Practice for electric, hydraulic and hand-powered rifts. This code gives general information and guidance for planning, purchasing, installati
31、on and maintenance of passenger, goods and service lifts. 3. In case of difficulty in classifying any equipment in accordance with the headings of Parts 1,4 and 5, reference should be made to the relevant definitions in Part 9. , AS Oct., added 1974 4. Part 4 of this standard applies to the engineer
32、ing and safetyrequirements for escalators and passenger conveyors. 5, In covering the requirements for escalators it has been borne in mind that, apart from their use by public transport undertakings, they are finding increasing application in shops and department stores. In the latter case they are
33、 frequently supplied by the manufacturers as complete units, with such items as machinery and control compartments forming an integral part of the escalator. This contrasts with the former case in which a machine room is usually provided. 6. The passenger conveyor was introduced only a few years ago
34、 as a method of transportation for moving persons over a horizontal distance with or without a change in level, and therefore as yet only limited experience is available on this form of transport. No doubt types other than those given in this part of the standard will be developed, and it is not the
35、 purpose of this part to preclude other types from being incorporated, providing they satisfy the safety standards required, giving particular attention to the movement of very young children and infirm or elderly persons who may use the facilities in shopping centres, airports, railway terminals, e
36、tc. 7. Throughout this standard *he metric and imperial systems of units are used side by side, but it is important that each contract shall either use the imperial - 7 ? BSI BS*2655 PART89 69 Lb24669 0005LOb T W BS 2655 : Part 4 : 1969 system throughout or the metric system throughout. A mixture of
37、 the two may lead to complications. It should be noted that in general, units have been con- verted from imperial to the metric system and then rounded off by increasing or reducing after taking into account the practical problems involved, and current Continent al practice. A 8. This Part of this s
38、tandard is rendered obsolescent concurrently with the publication of BS 5656 : 1983 Safety rules for the construction and installation of escalators and passenger conveyors under the conditions stated below. (1) This standard is no longer applicable to all new escalators and passenger conveyors inst
39、alled in such new buildings as are designed after the date of publiction of BS 5656 (3 1 October 1983). (2) All new escalators and passenger conveyors ordered after 3 1 October 1983, for installation in such buildings as have not yet been commenced but for which final plans existed before 3 1 Octobe
40、r 1983 should be constructed preferably in accordance with BS 5656 or in accordance with this standard. If, however, such installations are scheduled for commissioning after 3 1 : ! October 1987., the requirements of BS 5656 only are applicable, 1983, for installation in.such new buildings as were u
41、nder construction or coiiipleted before that date, are permitted to be constructed in accordance with either this standard or BS 5656, If, however, such installations are scheduled for commissioning after 3 1 October 1987, the requirements of BS 5656 only are applicable unless it can be shown that c
42、ompliance is not reasonably practicable. . (4) Siici iiew replacement escaatcirs and Passenier conveyors and major modifications to existing escalators and passenger conveyors as are commissioned before 3 1 October 1987, for use in existing buildings that were built before 31 October 1983, are permi
43、tted to be in accordance with either this standard or BS 5656. After 31 October 1987, the requirements of HS 5656 only are applicable unless it can be shown that compliance is not reasonably practicable. Special provisions are permissible to meet certain site conditions often present in buildings th
44、at have been in use for many years. It is intended that the use of new equipment should not automatically be restricted because certain site conditions are now more rigorous than formerly . The relevant requirements of this British Standard remain current only for the future maintenance and inspecti
45、ng of existing installations constructed in accordance with this British Standard. 9. In addition to the requirements specified in this standard and in BS 5656 readers should note that the Health and Safety Executive have published Guidance Note PM 34* Safety in the use of escalators which describes
46、 some of the inherent hazards and areas of risk experienced in the use of escalators and recommends certain precautions that should be taken to alleviate those hazards on both existing and new machines.

47、AL 1.1 SCOPE L; This parr o the stanbud applies to the engineering and Safe-/ requirements for escalators and passenger conveyors. The requirements for escalators are based on the steps being connected and driven by means of chains. Other types of construction may be adopted provided that the same s
48、tandard of safety is achieved throughout. The requirements for passenger conveyors are based on the use of two distinct types of treadway: I. Platforms interconnected by chains or other suitable means, and provided with grooks on the tread surface in the direction of travel (these conforming to the
49、specified.requirements for escalators). 2. Continuous endless belts with longitudinal grooves formed on the tread surface. Such aspects as limits of speed, width and angle of inclination are covered, together with methods of assessing contract loading. Also specified are require- ments for guarding, handrails, steps or belts, driving machinery and safety devices. Diagrams of a typical cross section and details of comb teeth and tread grooves are shown, containing limiting dimensions where applicable. The subject of potential hazards to users is discusse
