Road vehicles - Product data exchange between chassis and body work manufacturers (BEP) - Part 7: Coding of skip 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 skip loaders, to ensure an efficient and unambiguous communication of installation data between the parties involved.

Overview

ISO 21308-7:2018 - "Road vehicles - Product data exchange between chassis and body work manufacturers (BEP) - Part 7: Coding of skip loader bodywork" defines a standardized coding system for the exchange of installation and dimensional data for skip loaders. Part of the ISO 21308 BEP (Bodywork Exchange Parameters) series, this standard targets commercial vehicles (per ISO 3833) with a maximum gross vehicle mass over 3 500 kg and enables unambiguous product data exchange between truck chassis manufacturers, bodywork makers, importers, dealers and component suppliers.

Key topics and technical requirements

• BEP coding principles: Uses structured BEP codes (example format: BEP-ppMccc.n.p.q.s.t) to identify each characteristic of the skip loader and its interfaces to the vehicle.
• Units and data types: Preferred units are specified (millimetres for dimensions, kilograms for mass, Newtons for force, degrees for angles) to ensure consistent data reporting.
• Coordinate systems: Defines both the global vehicle coordinate system (ISO 4130) and a local skip loader coordinate origin (x,y,z) tied to main arm pivot and mounting plane for precise positioning.
• Geometrical data & space requirements: Codes for installation points, distances from axles, transport/tipping/loading positions and container handling clearances.
• Container and mass coding: Parameters for container dimensions, masses and mass points in transport and working positions.
• Interfaces: Coding for mechanical, hydraulic, electrical and electronic interfaces between skip loader, chassis and container.
• XML implementation guidance: Annex A gives instructions for mapping BEP codes to XML for electronic interchange in compliance with ISO 21308-1.

Practical applications and typical users

• Skip loader manufacturers use ISO 21308-7 to encode product dimensions and interface points for accurate vehicle mounting.
• Truck chassis manufacturers, importers and dealers rely on the standard to verify fitment and to supply consistent interface specifications.
• Bodywork integrators and upfitters use BEP-coded data for CAD/CAM modeling, installation planning and to avoid fitment errors.
• Component suppliers (cranes, loading equipment, demountables) use the coding to ensure compatibility.
• Fleet engineers and systems integrators benefit from improved interoperability, reduced engineering change orders, and streamlined data exchange via BEP XML.

Related standards

• ISO 21308-1 - General principles for product data exchange (BEP)
• ISO 21308-2 - Dimensional bodywork exchange parameters
• ISO 21308-3 - General, mass and administrative exchange parameters
• ISO 4130 - Vehicle coordinate system references
• ISO 3833 - Definition of commercial vehicles

Using ISO 21308-7:2018 improves clarity and reduces installation risk by standardizing skip loader dimension and interface data for digital exchange between chassis 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);
4 © ISO 2018 – All rights reserved

— 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 Skip loader coordinate system
For a default mounting position, the principle should be that the skip 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 skip loader
The origin of the coordinate system for a skip loader (referred to as zero reference point in this
document) is defined by:
— Local x = 0 for the plane through the centre of the main arm pivot point;
— Local y = 0 for the longitudinal plane through the centreline of the skip loader;
6 © ISO 2018 – All rights reserved

— Local z = 0 at the lower mounting plane of the skip loader subframe.
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.
