25、les for the construction and installation of lifts. See CEN/TR 81-10.

27、.1.1 The object of this European Standard is to give safety rules related to the construction and installation of accessible goods only lifts, with a view to safeguarding persons and objects against the risk of accidents associated with the use, maintenance and emergency operation of accessible good
28、s only lifts. This document is a type C standard as specified in EN ISO 12100-1. The accessible goods only lift installation concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are
29、 different to those, which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. 0.1.2 The following are to be safegua
30、rded: a) persons such as: 1) operators and users; 2) maintenance personnel; 3) persons in the near vicinity, outside the accessible goods only lift well, the machine room/spaces and pulley room/spaces (if any); b) objects such as components of the accessible goods only lift installation and load ins
31、ide the load carrying unit; c) building parts (see 0.2.5) such as those parts of the building which are directly associated with the accessible goods only lift. 0.2 Principles 0.2.1 In drawing up this European Standard the following have been used: 0.2.2 This European Standard does not repeat all th
32、e general technical rules applicable to every electrical, mechanical, or building construction including the protection of building elements against fire. 0.2.3 This European Standard addresses the essential safety requirements of the Machinery Directive including those related to the well and machi
33、nery spaces, excluding any other requirement for the building. There can be in some countries regulations for the construction of buildings, etc,. which cannot be ignored. Typical clauses affected by this are those defining minimum values for the height of the machine and pulley rooms and for their
34、access doors dimensions. 0.2.4 When the weight, size and/or shape of components of the machinery prevent them from being moved by hand, they are either: a) fitted with attachments for lifting gear; or b) designed so that they can be fitted with such attachments (e.g. by means of threaded holes); or
35、BS EN 81-31:2010EN 81-31:2010 (E) 6 c) shaped in such a way that standard lifting gear can easily be attached. 0.2.5 Negotiations have been made between the parties involved and decisions have been taken, particularly about: a) the intended use of the accessible goods only lift and its limits; b) en
36、vironmental conditions, including surrounding lighting; c) compliance of the civil engineering with the requirements of this European Standard for those parts of the installation, which belong to the building and are not provided by the manufacturer. 0.3 Assumptions 0.3.1 Risks have been considered
37、for each component that may be incorporated in a complete accessible goods only lift installation. Rules have been drawn up accordingly to mitigate such risks. 0.3.2 Components are: a) designed in accordance with usual engineering practice and calculation codes, taking into account all failure modes
38、; b) of sound mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality. Harmful materials, such as asbestos, are not used. 0.3.3 The machine is kept in good repair and working order, so that the initial safety level is maintained. 0.3.4 The IP code
39、of electrical components is selected in relation with the intended use where not specified in this European Standard in accordance with EN 60529. 0.3.5 By design of the load bearing elements, a safe operation of the accessible goods only lift is assured for loads ranging from 0 % to 100 % of the rat
40、ed load, including provisions for taking into account possible overloading. 0.3.6 The requirements of this European Standard regarding electric safety devices are such that the possibility of a failure of an electric safety device complying with all the requirements of the standard needs not to be t
41、aken into consideration. 0.3.7 A user may, in certain cases, make one imprudent act. The possibility of two simultaneous acts of imprudence and/or the abuse of instructions for use is not considered. 0.3.8 If in the course of maintenance work a safety device, normally not accessible to the user, is
42、deliberately neutralised, safe operation of the accessible goods only lift is no longer assured, but compensatory measures will be taken to ensure safety of all persons in conformity with maintenance instructions according to EN 13015. It is assumed that maintenance personnel are instructed and work
43、 according to the instructions. 0.3.9 For horizontal forces, the following have been used: a) static force: minimum 300 N; b) force resulting from impact: minimum 1 000 N, reflecting the values that one person can exert. BS EN 81-31:2010EN 81-31:2010 (E) 7 Higher values need to be taken into account
44、 where powered or hand powered means for loading and unloading are intended to be used (see 0.2.5). 0.3.10 With the exception of the items listed below, a mechanical device built according to good practice and the requirements of the standard will not deteriorate to a point of creating hazard withou
45、t the possibility of detection as long as regular and periodical examinations, tests and maintenance are carried out according to the instruction manual delivered with the installation. The following mechanical failures, where applicable, are considered in the requirements: a) breakage of the suspen
46、sion; b) uncontrolled slipping of the ropes on the traction sheave; c) breakage and slackening of all linkage by auxiliary ropes, chains and belts; d) failure of one of the mechanical components of the electromechanical brake which takes part in the application of the braking action on the drum or d
47、isk; e) failure of a component associated with the main drive elements and the traction sheave; f) rupture in the hydraulic system (jack excluded). 0.3.11 When the speed of the load carrying unit is linked to the electrical frequency of the mains up to the moment of application of the mechanical bra
48、ke, the speed is assumed not to exceed 115 % of the rated speed or a corresponding fractional speed. 0.3.12 When the device according to 5.2.14 is provided, the organisation within the building, where the accessible goods only lift is installed, is such that it can respond effectively to emergency calls without undue delay (see 0.2.5). 0.3.13 Means of access are provided for the hoisting of heavy equipment (see 0.2.5). 0.3.14 To ensure the correct functioning of the equipment in the machinery spaces, the ambient temperature in these spaces is assumed to be maintained between + 5 C and + 40 C
