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.
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 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 identifying 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 of users and does not

Introduction
Based on the ISO BEP system for coding of bodywork exchange parameters, this part of ISO 21308
specifically deals with the coding of dimensions and other characteristics of loader cranes. The aim is
to ensure an efficient and unambiguous communication of dimensional installation data between the
parties involved. The BEP coding covers also main characteristics of hydraulic, electrical, and electronic
interfaces to the vehicle. XML coding for communication of the related BEP data is included as well.
This part of ISO 21308 is useful for all parties involved in the installation of cranes to vehicles, e.g. loader
crane manufacturers, truck chassis manufacturers, and bodywork manufacturers.
INTERNATIONAL STANDARD ISO 21308-5:2014(E)
Road vehicles — Product data exchange between chassis
and body work manufacturers (BEP) —
Part 5:
Coding of loader crane bodywork
1 Scope
The ISO 21308 series describes a generic system for the exchange of data between truck chassis
manufacturers and bodywork manufacturers. It applies to commercial vehicles as defined in ISO 3833,
having a maximum gross vehicle mass above 3 500 kg.
The process of exchanging the above information can involve
— chassis manufacturers,
— chassis importers,
— chassis dealers,
— one or more bodywork manufacturers, and
— bodywork component suppliers, e.g. manufacturers of demountable bodies, cranes and loading
equipment, and tipping equipment.
This part of ISO 21308 specifically describes the coding dimensions and other characteristics of loader
cranes and auxiliary stabilizers, to ensure an efficient and unambiguous communication of installation
data between the parties involved.
This part of ISO 21308 covers loader cranes as specified in ISO 15442, designed to be fitted on commercial
vehicles (including trailers).
This part of ISO 21308 is not applicable to other load-lifting systems (e.g. tail lifts, hook loader systems).
