The machinery concerned and the extent to which hazards are covered are indicated in the Scope of this standard. I
23、t is assumed that: negotiations shall take place between manufacturer and user about specific local installation conditions; risk analysis of each component that may be incorporated in a complete SAE installation has been made. Rules have been drawn up on the basis of this assumption; the safety req
24、uirements of this standard have been drawn up on the basis that the components are: a) designed in accordance with the usual engineering practice and calculation codes, including all failure modes; b) of sound mechanical and electrical construction; c) made of materials with adequate strength and of
25、 suitable quality; and d) free of defects; harmful materials, such as asbestos are not used; the equipment is kept in good working order; any mechanical device manufactured according to good practice and the requirements of this standard shall not deteriorate to the point of creating a hazard withou
26、t being detected; the ambient temperature range is between 210 8C and +55 8C. Additional requirements for equipment intended for use outside the ambient temperature range are set out in annex D; the parapets and roofs are of adequate strength for the SAE equipment to be installed. 1 Scope 1.1 Applic
27、ation This standard specifies the safety requirements for suspended access equipment (SAE). It is applicable to both permanent and temporary equipment which may be powered or hand operated and which are defined in clause 3. 1.2 Hazards This European Standard deals with significant hazards pertinent
28、to SAE, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This European Standard specifies appropriate technical measures to eliminate or reduce risks arising from the significant hazards. 1.3 Exclusions The following are not covered: a) operation i
29、n severe conditions (e.g. extreme environmental conditions, corrosive environment, strong magnetic fields, etc.); b) operation subject to special rules (e.g. potentially explosive atmospheres, work on live lines); c) transportation of passengers from one level to another; d) handling of loads, the n
30、ature of which could lead to dangerous situations (e.g. molten metal, acids/bases, radioactive materials, brittle loads); e) hazards occurring when handling suspended loads in conjunction with the suspended platform; f) hazards occurring when used on public roads, over water, or wherever it is not p
31、ossible to lower the platform to a safe position; g) hazards arising from wind pressure acting on loads having a surface area in excess of 2 m2; h) SAE using cableless control systems. The following applications for SAE are excluded from this standard: access to working areas with an incline in exce
32、ss of 458 compared to the vertical; working platforms suspended by cranes; silo access equipment; access equipment using fibre ropes or chains for the suspension of the platform; SAE intended to be used underground; SAE powered by combustion engines; SAE intended to be used in shafts. 2 Normative re

38、 EN 1050:1996, Safety of machinery Risk assessment. 3 Definitions For the purpose of this standard, the following definitions apply. They are classified in terms of key words. 3.1 building maintenance unit (BMU) BMUs are SAE intended to be permanently installed and dedicated to a specific building o
39、r structure. BMUs consist of a platform, suspended from a suspension rig which is generally a trolley unit with hoist, operating either on rails or on a suitable surface, e.g. concrete track. Monorails with traversing trolleys or other suspension rigs, e.g. davits, fixed to the building, from which
40、a platform may be suspended, shall be considered as parts of a BMU NOTEBMU are intended to be used by operators for inspection, cleaning and maintenance of a building where the general public may have access below the suspended platform. 3.2 temporary suspended platforms (TSP) TSPs are SAE which are
41、 temporarily installed on a building or structure for specific tasks. TSPs consist of a platform and suspension rig which are assembled prior to use on a work site. They are dismantled and removed from site on completion of the work for which they were installed NOTETSPs are intended to be used by o
42、perators for, e.g. construction, cladding, painting, maintenance and refurbishment of buildings, bridges, chimneys and other structures. 3.3 Personnel 3.3.1 competent person designated person, suitably trained, qualified by knowledge and practical experience and provided with the necessary instructi
43、ons to enable the required task to be carried out safely 3.3.2 operator designated person, suitably trained for working at height, qualified by knowledge and practical experience and provided with the necessary instructions to enable operations to be carried out on SAE 3.4 Hoist 3.4.1 drum hoist hoi

45、lowers the suspension rope by passing the rope around two gear driven grooved multiwrap capstan drums, and transferred to a wire rope winder designed to apply a tail load to the capstan drum system 3.4.4 jaw operated traction hoist hoist where the traction assembly consists of two pairs of jaws 3.4.
