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 subject 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 (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 committees 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 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.
This second edition cancels and replaces the first edition (ISO 15442:2005), which has been
technically revised.

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.
When requirements of this type-C standard are different from those which are stated in type-A or B standards,
the requirements of this type-C standard take precedence over the requirements of the other standards for
machines that have been designed and built according 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.
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 existing
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 well 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.
INTERNATIONAL STANDARD ISO 15442:2012(E)
Cranes — Safety requirements 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 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 special 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 manufacturer. 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.
