ISO 21308-6:2018

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.
