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).

Introduction
Based on the ISO BEP (bodywork exchange parameters) system, this document specifically deals with
the coding of dimensions and other characteristics of skip loaders. The aim is to ensure an efficient and
unambiguous communication of dimensional installation data between the parties involved.
The document also covers coding of characteristics of hydraulic, electrical and electronic interfaces to
the vehicle.
The document is useful for all parties involved in the installation of skip loaders to vehicles, e.g. skip
loader manufacturers, truck chassis manufacturers, and bodywork manufacturers.

Road vehicles — Product data exchange between chassis
and body work manufacturers (BEP) —
Part 7:
Coding of skip loader bodywork
1 Scope
This document 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 manufacturer;
— chassis importer;
— chassis dealer;
— one or more bodywork manufacturers; and
— bodywork component suppliers, e.g. manufacturers of demountable bodies, cranes and loading
equipment, tipping equipment.
This document specifically deals with the coding of dimensions and other characteristics of skip
loaders, to ensure an efficient and unambiguous communication of installation data between the
parties involved.

skip loader
vehicle mounted powered equipment comprising of two arms moving around a pivoting axis, using
chains or similar for loading, unloading and tipping containers and other demountables
Note 1 to entry: Arms are usually moving in parallel. They may be fixed, extendable or articulated.
Note 2 to entry: Figure 1 shows the main parts of a skip loader referred to in this document.

4 Coding principles
4.1 BEP codes of bodywork for hook loaders
Each characteristic, related to the hook loader and its interfaces to truck chassis, is assigned a code
composed of the items given below. A prefix “BEP”, followed by a dash (-), shall be used to avoid
confusion with other coding systems.
BEP codes are formatted according to the principles in Table 1.
Table 1 — BEP coding principles
BEP-ppMccc.n.p.q.s.t
Item Assignment Description
pp Bodywork category pp = None or 00 for codes related to vehicle chassis (ISO 21308-2 and
ISO 21308-3)
pp = 01 for codes related to loader cranes (ISO 21308-5)
pp = 02 for codes related to hook loaders (ISO 21308-6)
pp = 03 for codes related to skip loaders (ISO 21308-7)
Future parts of the ISO 21308 series may introduce new pp numbers.
M Measure type A capital letter, which denotes the type of code:
H = Z direction, coordinate system in accordance with ISO 4130
L = X direction, coordinate system in accordance with ISO 4130
W = Y direction, coordinate system in accordance with ISO 4130
C = Coordinate (x,y) or (x,y,z) in the Cartesian coordinate system
R = Radius
V = Angle
M = Mass (m), or mass point (m,x,y,z)
F = Force (static or dynamic)
T = Moment (static or dynamic)
G = General
A = Administrative
ccc BEP code number Code number given by the standard
.n Index number
