15、try Standards Committee, is a revision of and supersedes the1958 edition of BS2655, which was entitled “Electric lifts”. The new title reflects the extension of the scope of this British Standard. Amendments to Parts2 and3 have been published, and implement the change in title. The revised Part1 and
16、 additional new parts are being published separately and, together with Parts2 and3, are as follows: Part 1: General requirements for electric, hydraulic and hand-powered lifts. This part is basically a revision of the1958 edition of BS2655-1 1) , without the building requirements and list of defini
17、tions, 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 of electric motor specially designed for driving lifts. It sho
18、uld be used in conjunction with BS2613 2)and gives additional requirements, including the class of lift rating and special limits of temperature rise. Part 3: Arrangements of standard electric lifts. This part gives standard dimensions for lift wells and machine rooms in relation to lift capacity an
19、d platform sizes, for seven classes of lifts. Part 4: General requirements for escalators and passenger conveyors. This part specifies engineering and safety requirements for escalators and passenger conveyors. The latter may be described as machines in which the passenger carrying surface remains p
20、arallel to the direction of motion and is uninterrupted. Part 5: General requirements for paternosters. This part specifies engineering and safety requirements for paternosters, which may be described as machines where series of cars are continuously running in closed loops and are characterized by
21、the car floors remaining substantially horizontal when the direction of motion is reversed at the extremities of car travel. Part 6: Building construction requirements. This part specifies structural and fire resistance requirements for the equipment covered by Parts1,4 and5. Part 7: Testing and ins
22、pection. This part specifies tests, examination and certification of new and modified equipment covered by Parts1,4 and5. Part 8: Modernization or reconstruction of lifts, escalators and paternosters. This part specifies engineering and safety requirements. Part 9: Definitions. This part gives defin
23、itions of terms used in the remainder of the standard. Part 10: General requirements for guarding. This part specifies requirements for the guarding of moving parts and protection against hazards from electrical equipment. It relates to equipment covered in Parts1,4 and5. CP407:1972. British Standar
24、d Code of Practice for electric, hydraulic and hand-powered lifts. The code gives general information and guidance for planning, purchasing, installation and maintenance of passenger, goods and service lifts. In case of difficulty in classifying any equipment in accordance with the headings of Parts
25、1,4 and5, reference should be made to the relevant definitions in Part9. This Part6 of the standard applies to the building construction requirements for the equipment covered by Parts1,4 and5. Those clauses of the text which relate to powered lifts are based on Appendix B of the1958 edition of BS26
26、55-1, with the following broad change. The requirements for top clearances and bottom overtravel, formerly part of Appendix B, are now transferred to the main body of Part1 of the standard. 1) BS2655, “Electric lifts” Part1: “General Requirements”. 2) BS2613, “The electrical performance of rotating
27、electrical machinery”.BS2655-6:1970 BSI 07-1999 iii The building requirements for the equipment covered by the standard have been brought together under one cover because of their interest to the architect or other person responsible for specifying the details of building construction. This last men
28、tioned function is not, of course, the prime responsibility of the equipment manufacturer. In covering the building construction 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 dep
29、artment stores. In the latter case they are 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 provided. Throughout this standard t
30、he metric and imperial systems are used side by side, but it is important that each contract shall use either the metric system throughout or the imperial system throughout. A mixture of the two may lead to complications, particularly in relation to ratings of lifts and lift speeds. Section2 of this
31、 Part of this standard is rendered obsolescent concurrently with the publication of BS5655 “Lifts and service lifts” Part1:1979 “Safety rules for the construction and installation of electric lifts” and Part2:1983 “Specification for hydraulic lifts”, under the implementation conditions stated in tho
32、se standards. The relevant requirements of section2 of BS2655-6:1970 remain current only 1) when applied to service lifts, hand-powered lifts, paternosters, escalators and passenger conveyors as specified in sections3,4,5 and6 and when specific clauses in section2 are invoked in those sections; 2) w
33、hen required for the future maintenance and inspection of existing electric or hydraulic installations constructed in accordance with BS2655. Although BS2655-4:1969 “General requirements for escalators and passenger conveyors” has also been made obsolescent by the publication of BS5656 “Safety rules
34、 for the construction and installation of escalators and passenger conveyors” the building requirements specified in section6 are still relevant pending the transfer of those requirements to a specification related to BS5656. A British Standard does not purport to include all the necessary provision
35、s of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages1to 9 and a back
36、 cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.iv blankBS2655-6:1970 BSI 07-1999 1 1 General 1.1 Scope This Part of this British Standard applies to the building constructio
37、n requirements for escalators, lifts, passenger conveyors and paternosters. The requirements for lifts are subdivided into those for powered lifts and hand-powered lifts. Additional building work requirements (such as fixings, cutting away for switches and “making good”) are not covered by the stand
38、ard, and reference should be made to the drawings supplied by the manufacturer of the equipment. 1.2 Statutory regulations Where reference is made in this standard to the “Building Regulations”, this means compliance with: 1) the Building Regulations, 1965, applicable in England and Wales except inn
39、er London; 2) the London Building Acts, 1930:1939, and Construction byelaws in force thereunder, or 3) the Building Standards (Scotland) Regulations, 1963; 4) any revisions to the above currently in force. 2 Passenger and goods lifts (powered) 2.1 Lift well construction A lift well, in association w
40、ith its machine room, shall be arranged for the car and its counterweight to travel in the same lift well in juxtaposition to one another. The use of lift wells shall be restricted to the lift installation, and no other services shall be accommodated therein. The well, however, may contain certain h
41、eating equipment for the lift well, excluding hot water and steam heating; any control and adjustment devices shall be located outside the well. The lift well shall not form part of the ventilation system of the building. Where two or more lifts are fixed in a common lift well, a rigid partition hav
42、ing a minimum height of2.5m shall be fixed at the bottom between any two lifts. If the horizontal distance between the edge of a car roof and a moving part (car or counterweight) of an adjacent lift is less than300mm, this partition shall be extended for the full height of the well and over the widt
43、h to be guarded. This width shall be at least equal to that of the moving part (or part of this) which is to be guarded, plus0.1m on each side. 2.2 Lift well enclosure 2.2.1 Materials of construction. Lift well enclosures shall be provided and shall be continuous on all sides from the pit to the top
44、 of the lift well. Such enclosures shall be imperforate except for doors and necessary access panels. 2.2.2 Strength. Lift well enclosures shall be of sufficient strength to support the lift guides at appropriate intervals, and to support in true alignment the landing doors with operating mechanisms
45、 and locking devices. The structure of the well shall also be capable of supporting the loads that may be imposed by the machine, the guides during safety gear operation, the buffers, the tie down (anti-jump) device, etc. Non-structural parts of the enclosure shall be capable of withstanding a horiz
46、ontal force of440N(45kgf) or100lbf applied at any point without under-going elastic deformation of more than25mm or1in. 2.2.3 Fire resistance 2.2.3.1 The material of construction shall be non-combustible and shall not be such that it might give off harmful gas or fumes in case of fire. Where there i
47、s a statutory requirement for fire resistance of lift well enclosures and doors, the requirements of the current issue of the building regulations shall apply. 2.2.3.2 When the entrances having access to the lift well have doors which automatically close, the degree of fire resistance of the entranc
48、es shall be at least half that required for the enclosure. Thus for lift well enclosures, the fire resistance of which is required to be one hour or less, the required fire resistance of the entrance shall be half an hour. Where the required fire resistance of the lift well enclosure is greater than
49、 one hour but not more than two hours, the required fire resistance of the entrance shall be one hour. 2.2.3.3 When the entrances having access to the lift well have doors which are manually closed, the degree of fire resistance of the entrances shall not be less than that required for the enclosure. Thus for lift well enclosures, the fire resistance of which is required to be no greater than half an hour, the required fire resistance of the entrance shall be half an hour. When the required fire resistance of the lift well enclosure is greater than half an hour bu
