10、6 ISO 15442:2012(E) Foreword ISO (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 s
11、ubject 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
12、(IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical comm
13、ittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not
14、be held responsible for identifying any or all such patent rights. ISO 15442 was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 6, Mobile cranes. T h i s s e c o n d e d i t i o n c a n c e l s a n d r e p l a c e s t h e f i r s t e d i t i o n ( ISO 15442:2005), which has been
15、technically revised.iv ISO 2012 All rights reserved ISO 15442:2012(E) Introduction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. W h
16、en r equ i r ement s of t h i s t y pe - C s t a nda r d a r e d i f fer ent f r om t hose wh ich a r e s t at ed i n t y pe -A or B s t a nda r d s, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built a
17、ccording to the requirements of this type-C standard. Even though a loader crane mounted on a chassis may be considered as a particular type of mobile crane, with very few exceptions International Standards developed for mobile cranes do not currently include specific requirements for loader cranes.
18、 This International Standard identifies specific safety requirements for loader cranes, when applicable, refers to existing International Standards which contain provisions that can be applied to loader cranes, promotes loader crane safety by both identifying specific requirements and referring to e
19、xisting applicable standards, so that incorporating all such provisions into the design and use of loader cranes will guard against and minimize injury to workers and damage to equipment, facilitates the work of everyone in the field of loader cranes (designers, supervisors and other personnel, as w
20、ell as people directly or indirectly responsible for their safe use and maintenance) who needs to consult currently available International Standard for loader cranes, and contributes to the further international harmonization of loader crane standards.

21、equirements for loader cranes 1 Scope This International Standard specifies the minimum requirements for the design, calculation, examination and testing of hydraulic powered loader cranes and their mountings onto chassis or static foundations. It is applicable to all new loader cranes manufactured
22、one year after its publication. It is not the intent of this International Standard to require the retrofitting of existing loader cranes. It is not applicable to loader cranes used on board ships or floating structures or to articulated boom system cranes designed as a total integral part of specia
23、l equipment such as forwarders. It deals with all significant hazards, hazardous situations or hazardous events relevant to loader cranes, with the exception of hazards related to the lifting of persons, when used as intended and under conditions of misuse which are reasonably foreseeable by the man
24、ufacturer. See Annex A for a list of the significant hazards. NOTE The use of cranes for the lifting of persons may be subject to specific national regulations. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for

35、NOTE 1 ISO 3833:1977 defines commercial vehicle as a motor vehicle which, on account of its design and appointments, is used mainly for conveying goods, and which may also tow a trailer. An example of one type of commercial vehicle equipped with a loader crane is shown in ISO 4306-2:2012, Figure 9.
36、NOTE 2 A loader crane installed on another type of vehicle or on a static base is still considered a loader crane.
