11、S 6037:1990 ii BSI 12-1998 Foreword This British Standard has been prepared under the direction of the Civil Engineering and Building Structures Standards Policy Committee. This edition introduces technical changes but it does not reflect a full review or revision of the standard which will be under
12、taken in due course. It replaces BS 6037:1981 together with its amendments No. 1 and No. 2 which are withdrawn. The principal changes from the previous edition are as follows. a) The testing procedure has been modified considerably. b) Details are given of a commissionary certificate, test and exami
13、nation certificates and a rejection note. c) Further instructions are given on exchange of information before contract. d) The permissible degree of inclination on the platform has been relaxed. As a code of practice this document is not a specification of the components of a permanent installation.
14、 It is a statement of the more important rules that should be followed in the design, construction and use of the components. It is also intended to establish the safe conditions for those persons having access to and from or using the equipment, or otherwise engaged nearby. For recommendations rela
15、ting to temporarily installed suspended scaffolds and access equipment, reference should be made to BS 5974. Some buildings may have permanently installed roof trolleys or other suspension systems for which a temporary cradle, platform or chair, is brought to site and fitted, as necessary, to facili
16、tate window cleaning or facade maintenance operations. All such equipment should comply with the certification requirements of clause 19.3 of this code. It should, in addition, comply with clause 22 of BS 5974:1990 which recommends that a valid certificate in respect of the temporary components be i
17、ssued on each occasion the installation is brought into use. It should be recognized that the requirement for safe and efficient window cleaning and facade maintenance procedures can, in general, only be satisfied by the installation of a permanent system with dedicated cradle. A British Standard do
18、es not purport to include all the necessary provisions 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 ins

20、d Dec 06 12:36:54 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 6037:1990 BSI 12-19981 0 Introduction A permanent installation is designed and erected to provide a working platform to give access to parts of a permanent structure and to serve only that structure, although parts of the installation m
21、ay be demountable for storage purposes. A permanent suspended access system comprises a working platform suspended on ropes from a securely mounted overhead structure. It may be capable of being raised and lowered, and of being moved laterally across the face of the building. Such installations are
22、customarily used for maintenance and window cleaning. The roof trolley may be mounted on rails or tracks on top of the roof or may be suspended from the underside of a cantilevered portion of the building. The installation may be power or manually operated or a combination of both. The winches or cl
23、imbing devices may be mounted either on the overhead structure or on the platform. It is essential that care is taken to ensure compliance with the manufacturers design data as recommended in appendix B. 1 Scope This code of practice sets out the basic recommendations for the construction, installat
24、ion and use of permanently installed suspended access equipment. When considering a design for a new installation, suspended access equipment, used on a completed building to provide for its continuing routine maintenance, should be classed as permanent and then comes within the scope of this code.

42、983 3.31 sacrificial overspeed device a safety device which acts as a fail-safe final stop should the primary and secondary brakes fail to sustain the cradle or platform from dropping 4 Access It is important that adequate and safe means of access to all parts of the installation be provided, and us
43、ed. This is necessary not only to provide access for the use of the equipment but also to allow for the routine examination and maintenance of the equipment to be carried out easily and in safety. In the case of an underslung installation, a safe place should be provided from which the recommended i
44、nspections can be carried out in safety, being a point independent of the equipment being tested. When access is from the roof of the building a safe route should be provided between the roof and the inside of the building. All users should be made aware of the approved means of access and egress. T
45、he provisions that should be incorporated in the design to allow for safe escape in the case of a malfunction of the equipment are described in 17.4. 5 Preliminary planning and exchange of information The provision of safe and easy access for activities such as inspection, cleaning and building main
46、tenance is an important factor in the design of a building. A permanent installation can affect the structure and fenestration of a building and therefore the requirements should be considered at the preliminary design stage of the building. Significant savings and design advantages can result from
47、an early consideration of access requirements. The preliminary design should be based on reliable advice and guidance concerning the various types of system available, and the general planning details should be settled at the earliest possible stage by detailed investigation with the purchasers repr
48、esentative, reaching agreement with the equipment maker where necessary, before an order is finally placed. This will enable a check to be made, and information to be exchanged, on such vital matters as: a) the number, type, capacity and operating speed of the suspended access equipment required; b)
49、 the provision of safe access to the roof and equipment; c) the wind loading for which the building has been designed; d) the loads which the equipment will impose on the building structure; e) the dimensions and clearances required for the operation of, and access to, the equipment; f) the special requirements of local authorities and other requirements set out in the “planning permit”; g) the requirements for providing and fixing suitable mullion guides or other fixtures to the building face where necessary; h) the need for the builder to maintain accuracy of building as t
