10、16ISO 10571:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub
11、ject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (I
12、EC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be
13、noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifyi
14、ng any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience
15、of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Suppl

17、10571:2016INTERNATIONAL STANDARD ISO 10571:2016(E)Tyres for mobile cranes and similar specialized machines1 ScopeThis International Standard specifies the designation, dimensions, load ratings and reference speed for tyres and rims fitted to vehicles, such as all-terrain equipment, mobile cranes, cr
18、ash tenders, etc., likely to operate on highway over long distances at reference speed and under constant load.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edi
19、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 42091:2001, Truck and bus tyres and rims (metric series) Part 1: TyresISO 42231, Definitions of some terms used in the tyre industry Part 1: Pneumatic tyresISO 42503, Eart
20、h-mover tyres and rims Part 3: Rims3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 4223-1 apply.NOTE Equivalent terms are given in ISO 3877-1.4 Tyre designation and markingThe designation of the tyre shall be shown on its sidewall and shall include th
21、e details in 4.1. Additional markings as shown in 4.2, 4.3 and 4.4 may also be included as required by regional regulations or practices.4.1 Tyre size designation and service descriptionTyres for mobile cranes in accordance with this International Standard shall be indicated as follows:Nominal secti
22、on widthNominal aspect ratioTyre construction codeNominal rim diameter codeService description4.1.1 Nominal section widthThe nominal section width shall be expressed in millimetres, ending in “5”. See Annex A for nominal section width steps.4.1.2 Nominal aspect ratioThe nominal aspect ratio shall be
23、 expressed as a percentage and shall be a multiple of five. ISO 2016 All rights reserved 1BS ISO 10571:2016ISO 10571:2016(E)4.1.3 Tyre construction codeThe tyre construction code shall be as follows: (dash) for diagonal/bias construction“R” for radial ply construction.In addition, the word “RADIAL”
24、may also appear on the tyre.4.1.4 Nominal rim diameter codeThe nominal rim diameter shall be expressed by a code, in accordance with ISO 4250-3.4.1.5 Service descriptionThe service description may be indicated as follows:Load index Speed symbol4.1.5.1 Load indexThe load index is a numerical code ass
25、ociated with the maximum load a tyre can carry at the speed indicated by its speed symbol.The correlation between load indices and tyre load-carrying capacity (TLCC) is as given in Table 1.4.1.5.2 Speed symbolThe speed symbol indicates the speed category at which the tyre can carry the load correspo
26、nding to its load index.Tyres for mobile cranes in accordance with this International Standard have speed symbol “E” or “F”, which correspond to 70 km/h and 80 km/h, respectively.4.2 Service identification (Regional option)The word “ROAD” may be used to identify these tyres that can be used on roads
27、 over long distances at reference speed and under constant load.4.3 Load range (Regional option)Where required by regional regulations, the tyre load range shall be as shown in Table 2.4.4 Other service characteristics4.4.1 In the case of tubeless tyres, the marking “TUBELESS” shall be shown on the
28、tyre.4.4.2 In the case of a preferred direction of rotation of the tyre, an arrow shall be used to indicate that direction.4.5 ExampleA mobile crane tyre having the following characteristics shall be marked as “605/80R25 188E ROAD Load Range L”:a) a size and construction of nominal section width 605

31、n width and overall diameter;d) maximum tyre dimensions in-service.6 Tyre load capacities6.1 Basic tyre loadsBasic tyre load ratings at 70 km/h (speed symbol E) reference speed are given in Table 5 and Table 6 for 95 series and 80 series tyres, respectively, and at 80 km/h (speed symbol F) reference
32、 speed, in Table 7 and Table 8, for the 95 series and 80 series tyres, respectively.6.2 LimitationsIn some countries, there can be load/speed/inflation pressure limitations because of national requirements.6.3 Tyre loads at speeds other than reference speedWhen a tyre is fitted on a vehicle with a m
33、aximum speed capability different from the tyre reference speed, load capacities shall be modified as shown in Table 9 and Table 10.6.4 Tyre selectionSpeed symbol E tyres are used primarily for cranes with low speed capability (rough terrain applications). Cranes with higher speed capability (all-te
34、rrain applications) can require a speed symbol F tyre. Speed symbol E and speed symbol F tyres are not interchangeable on a given application because of the difference in their load carrying capability at the same speed (refer to Table 5, Table 6, Table 7 and Table 8).
