13、 This British Standard has been prepared under the direction of the Mechanical Engineering Standards Committee. This Part is identical with ISO1819 “Continuous mechanical handling equipment Safety code General notes”, developed by Technical Committee ISO/TC 101, Continuous mechanical handling equipm

14、ent, and lays down rules for the safety of personnel in the use of continuous mechanical handling equipment under normal working conditions when carrying loose bulk materials on unit loads. It is important that both manufacturers and users of such equipment are aware of the latest safety regulations

15、. Attention is therefore drawn toAppendix Z of this standard. This standard forms part of a series concerned with continuous mechanical handling. The other Parts which also implement ISO publications relate to special safety rules. This standard is complementary to the other British Standards dealin

16、g with conveyors, i.e. BS2567, BS2890, BS4409 and BS4531. It does not in anyway supersede them. Terminology and conventions. The text of the international standard has been approved as suitable for publication, without deviation, as a BritishStandard. Some terminology and certain conventions are not

17、 identical with those used in British Standards; attention is especially drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard”

18、appear, referring to this standard, they should be interpreted as “British Standard”. Cross-references. The references to ISO/TR5045, ISO/TR5046 and ISO/TR5047 constitute informative matter only. ISO/TR5046 has been implemented as Part18 in this series. Technically equivalent British Standards will

19、also be produced for ISO/TR5045 and ISO/TR5047. Since no mandatory requirements are involved, the validity of this British Standard is not affected. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct

20、 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 and ii, pages1 to 10, an inside back cover and a back cover. This standard has been updated (see copyrigh

21、t date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS5667-1:1979 BSI 03-1999 1 0 Introduction It must be understood that the present International Standard applies only to conveying devices that have been correctly designed, and c

22、onstructed and erected with care. It must also be understood that the conveying device has been selected according to the characteristics of the product or the objects being conveyed, and is suitable for the working conditions. When the equipment conveys dangerous, noxious, toxic or harmful products

23、, the user shall inform the manufacturer and if necessary the erectors, and specify the special safety conditions to be complied with. 1 General 1.1 Scope This International Standard sets out safety rules relating to continuous mechanical handling equipment, including its construction, installation,

24、 utilization and maintenance, to ensure that it is used to the best advantage, and to prevent, as far as possible, any accidents or mishaps that could arise from misuse. To this end, these rules provide precise directives necessary to comply with legal texts (seeAppendix Z) and requirements decreed

25、by governing bodies in certain countries. 1.2 Field of application The safety rules laid down in this InternationalStandard apply in the normal working conditions defined in1.3.1, regardless of the use for which the equipment is intended. These safety rules limit the suppliers responsibility to cont

26、inuous mechanical handling equipment proper, excluding the structures (building frameworks, planks, etc.) to which such equipment is affixed or on which it is placed and for which the user is responsible, except when such structures have been designed, supplied and erected by the conveying device ma

27、nufacturer. The sole object of these rules is the safety of the personnel defined in1.3.2. Skilled personnel fitters, maintenance and repair personnel, who only work from time to time at the request of the person responsible for the plant shall observe special rules, particularly those set out in2.3

28、.17 to2.3.21. Persons whose duties do not demand their presence on the plant or in the vicinity of the equipment under consideration shall observe orders forbidding access to certain areas. 1.3 Definitions 1.3.1 normal working conditions specified conditions as agreed by the interested parties for t

29、he use of continuous mechanical handling equipment these normal working conditions will either be defined by the user and agreed with the manufacturer at the time of passing the order, or defined for standard equipment in the manufacturers catalogue when it is issued 1.3.2 personnel persons essentia

30、l to the use (the operation) of the continuous mechanical handling equipment itself and persons legitimately in the vicinity 1.4 General plan The safety code is divided into two parts: a) General rules relating to all continuous mechanical handling equipment for loose bulk materials or unit loads (c

31、overed by this International Standard). b) Special rules for continuous mechanical handling equipment for loose bulk materials or unit loads. These rules, written for individual appliances or groups of appliances, are covered by separate International Standards. Each part of the safety code is divid

32、ed into three clauses dealing with the safety rules applying to the following stages: construction (design and manufacture); installation (layout, erection and entry into service); utilization (operation and maintenance). 2 General rules The construction and operation of all continuous mechanical ha

33、ndling equipment for loose bulk materials and unit loads shall meet the legal and local requirements relating to safety in general 1) ; the principles laid down in clause1 of this International Standard; the following general rules. 1) SeeAppendix Z.BS5667-1:1979 2 BSI 03-1999 2.1 In the constructio

34、n stage (design and manufacture) 2.1.1 The stability and strength of the equipment (static or mobile) shall be ensured under all normal working conditions, including climatic conditions as agreed by the contracting parties. 2.1.2 The whole conveyor path and especially the loading, unloading and tran

35、sfer points, must be designed so as to avoid as much as possible all spillage of products or conveyed material. 2.1.3 The slopes and the characteristics of the conveying element must be designed so as to avoid slipping and/or unintentional dropping of the conveyed products under normal working condi

36、tions. The support element of the material or load (belt, buckets, swing trays, etc.) must have sufficient size to be suitable for the transport of the specified product or load. 2.1.4 To prevent over-running or running backwards of the conveying device, all inclined or vertical appliances shall inc

37、lude a safety device which operates whenever the motive power is cut off or fails and where the load conveyed possesses kinetic or potential energy. Nevertheless, a safety device for this purpose is not compulsory for those special cases which are specified in the special International Standards for

38、 each type of appliance. 2.1.5 Certain fixed or mobile appliances may include an articulated or mobile part in a vertical plane, actuated by motor or manually; in this case, there shall be a compulsory safety device for immobilizing such an articulated part in the event of voluntary or accidental st

39、oppage of the motive power even if the latter is manual. The lowering and raising system shall be fitted with a safety device to prevent accidental lowering or lifting of the boom, and to prevent kickback of any manually operated crank. The device for lowering and raising the movable part shall be s

40、o located that there is no necessity for the operator to be under the conveyor. The movement must be limited at the extreme positions, by stops capable of supporting the stress due to the load. The exceptions to this rule are mentioned in the special International Standards. 2.1.6 In cases of manual

41、 loading and/or unloading, the characteristics of the unit (height, width, speed, etc.) must be suitable for the working stations. The special International Standards give the necessary particulars. Mechanical devices must be installed: a) for the loading and unloading of unit loads exceeding55kg; b

42、) for the loading of unit loads when the vertical speed exceeds0,5m/s; c) for the unloading of unit loads when the vertical speed exceeds0,25m/s. 2.1.7 The in-running nips and pinch points of the conveying device (belts, chains, belt pulleys, etc.) and the movable parts (chain sprockets, spur gears,

43、 couplings, etc.) shall be protected if they are normally accessible to personnel 2) . 2.1.8 When shearing and squeezing points or zones exist on the path of the conveying element (for example at a change of direction, or the close approach to fixed parts, etc.), guards shall be provided 2) . 2.1.9

44、All movable parts giving access through mechanical handling equipment shall be designed so that they cannot be opened whilst the apparatus is working and so that the appliance cannot be used or started while they are “open”. 2.1.10 The loading and unloading openings of the enclosed units (in casing

45、or in housing) must be made in such a way that they prevent access to the moving components; otherwise suitable protection shall be provided. 2.1.11 Openings in enclosed appliances, which give access to moving parts, shall be guarded by covers which require a hand tool for removal or are locked or a

46、re interlocked with the drive to the equipment. Covers which it is necessary to open while the appliance is in operation shall expose a suitable fixed grating, which will prevent access. 2.1.12 Access to inspection holes shall be easy. 2.1.13 All the frequently used lubrication points shall be acces

47、sible without it being necessary to remove the guards. 2.1.14 It is recommended that equipment be so designed that cleaning is facilitated. 2) See the following technical reports: ISO/TR 5045, Continuous mechanical handling equipment Safety code for belt conveyors Examples for guarding of nip points

48、. ISO/TR 5046, Continuous mechanical handling equipment Safety code for conveyors and elevators with chain-elements Examples for guarding of nip points. ISO/TR5047, Continuous mechanical handling equipment Safety code for chain conveyors with bearing devices or load carriers Examples of protection.
