ISO 21308-5:2014

Overview

ISO 21308-5:2014 - Road vehicles - Product data exchange between chassis and body work manufacturers (BEP) - Part 5: Coding of loader crane bodywork is an ISO standard that defines how dimensional, mass, force and interface data for loader cranes and auxiliary stabilizers are coded for exchange between truck chassis and bodywork stakeholders. It is part of the ISO 21308 series and applies to commercial vehicles (ISO 3833) with a maximum gross vehicle mass above 3 500 kg. The standard covers loader cranes as specified in ISO 15442 and excludes other lifting systems (e.g., tail lifts, hook loaders). XML encoding for BEP data is provided in Annex A.

Key topics and technical requirements

• BEP coding framework: Uses the BEP code format (prefix “BEP”) to uniquely identify each crane-related characteristic (example format: BEP-ppMccc.n.p.q.s.t). This prevents ambiguity when exchanging product data between suppliers.
• Measure types and code semantics: Standardized measure-type letters (H, L, W, C, M, F, T, R, V, G, A) represent directions, coordinates, masses, forces, moments, radii, angles and administrative data to ensure consistent interpretation.
• Geometrical and space requirements: Definitions and coding for mounting positions, crane base dimensions, boom system geometry, slewing space, stabilizer positions and required clearances for installation.
• Masses, forces and moments: Coding of mass points in transport and working positions, masses with distances for stability calculations, and forces/moments necessary for structural and vehicle interface design.
• Interfaces and equipment data: Codes for mechanical interfaces, hydraulics, electrical/electronic interfaces, control stations and load lifting attachments to support integration with vehicle chassis systems.
• Units and data formats: Preferred units specified (mm for dimensions, kg for mass, N/kN for forces, N·m for moments, degrees for angles) and XML mapping for electronic exchange.

Applications and who uses it

ISO 21308-5:2014 is designed for practical use in:

• Loader crane manufacturers - to publish installation dimensions, masses and interface specifications.
• Truck chassis manufacturers and importers - to assess vehicle compatibility and plan anchoring/subframe interfaces.
• Bodywork manufacturers and installers - to design mounts, sub-frames and spatial layouts that accommodate cranes and stabilizers.
• Dealers and component suppliers - to support ordering, configuration and verification during upfit and delivery. Benefits include efficient, unambiguous communication, reduced installation errors, improved interoperability and streamlined digital data exchange.
