Road vehicles - Product data exchange between chassis and bodywork manufacturers (BEP) - Part 6: Coding of hook loader bodywork

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 hook loaders, to ensure an efficient and unambiguous communication of installation data between the parties involved.

Overview

ISO 21308-6:2018 - "Road vehicles - Product data exchange between chassis and bodywork manufacturers (BEP) - Part 6: Coding of hook loader bodywork" defines a standardized coding system for exchanging dimensional and interface data for hook loader (hook lift) bodywork. It is part of the ISO BEP (Bodywork Exchange Parameters) series and applies to commercial vehicles (per ISO 3833) with a maximum gross vehicle mass over 3 500 kg. The standard ensures efficient, unambiguous communication of installation data between chassis manufacturers, importers, dealers, bodywork manufacturers and component suppliers.

Key topics and technical requirements

• BEP coding principles and format: Uses BEP-prefixed codes (e.g., BEP-02L001) with a structured syntax (BEP-ppMccc.n.p.q.s.t) to identify bodywork characteristics unambiguously.
• Units and data types: Preferred units specified - dimensions and coordinates in millimetres (mm), masses in kilograms (kg), forces in N/kN, moments in Nm/kNm, angles in degrees (°).
• Coordinate systems and reference points:
  • Global vehicle coordinate system (X, Y, Z) per ISO 4130.
  • Local hook loader coordinates (x, y, z) with a defined zero reference point (tipping shaft centre plane, longitudinal pickup plane, lower mounting plane).
• Geometrical data and space requirements: Codes for installation distances, mounting hole locations, transport/tipping/loading positions, required clearances and maximum/minimum distances between reference points and interfaces.
• Container and handling dimensions: Coding of container frame dimensions and load/locking interfaces to ensure container compatibility with hook loaders.
• Mass and mass point coding: Mass points in transport and working positions and container mass definitions.
• Mechanical, hydraulic and electrical interfaces: Codes for mechanical mounting interfaces, hydraulic connections and electrical/electronic interfaces required for installation and operation.
• XML mapping: Annex A describes how BEP codes map to XML for electronic data exchange, following ISO 21308-1 XML requirements.

Practical applications and users

• Primary users: Hook loader manufacturers, truck chassis manufacturers, bodywork suppliers, component makers (demountable bodies, cranes, tipping equipment), chassis dealers and importers.
• Practical benefits:
  • Reduces installation errors by standardizing dimensional and interface data.
  • Simplifies vehicle configuration, procurement and manufacturing workflows.
  • Enables reliable electronic data exchange (XML/EDI) between OEMs and suppliers.
  • Supports CAD/CAM integration and faster aftermarket/upfitting processes.

Introduction
Based on the ISO BEP (bodywork exchange parameters) system, this document specifically deals with
the coding of dimensions and other characteristics of hook 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 hook loaders to vehicles, e.g. hook
loader manufacturers, truck chassis manufacturers, and bodywork manufacturers.

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 .n is used to designate object number n
.p Entity number .p is used to designate a certain set of object characteristics or entities (e.g.
dimensions, coordinates, address information)
Where both .n and .p are specified, they are given in the .n .p order.
.q Corner number .q is used to designate contour corner index number
.s Side designator L or R
.t Type designator .t is used to designate a certain type (e.g. “Rigid” or “Flexible”)
NOTE Dimensions, except for radius, can be positive or negative.
4.2 Units of BEP code values
The following units are preferred when reporting values related to BEP codes (see also ISO 21308-1):
— dimensions (L, W, H, R) and coordinates (x, y, z) in millimetres (mm);
— masses in kilograms (kg);
— forces in Newtons (N), or kN;
— moments in Newtonmetres (Nm), or kNm; and
— angles in degrees (°).
NOTE Guidance on units is shown in the unit column for each BEP code.
4.3 References for measurements
4.3.1 Global coordinate system (X, Y, Z)
A vehicle coordinate system according to ISO 4130 is applied, see Figure 2. Global coordinates for the
vehicle are denominated X, Y and Z (uppercase letters).
Figure 2 — Vehicle coordinate system according to ISO 4130
4.3.2 Hook loader coordinate system
For a default mounting position, the principle should be that the hook loader coordinate directions
should coincide with those of the vehicle. Local bodywork coordinates are denominated x, y and z
(lowercase letters), see Figure 3.

Figure 3 — Local coordinate system for hook loader
The origin of the coordinate system for a hook loader (referred to as zero reference point in this
document) is defined by:
— Local x = 0 for the plane through the centre of the tipping shaft;
— Local y = 0 for the longitudinal plane through the single pickup point of the hook loader; and
— Local z = 0 at the lower mounting plane of the hook loader subframe.
NOTE For installation of a hook loader on a truck chassis, an additional frame could be required between the
chassis top mounting plane and hook loader lower mounting plane.
4.4 Related XML coding
Any XML implementation for the communication of BEP codes shall follow the requirements given in
ISO 21308-1. The XML coding related to this document shall be written according to the indications
in Annex A
