Overview
ISO 7131:2009 - Earth-moving machinery - Loaders - Terminology and commercial specifications defines standardized terminology and the content of commercial literature for self‑propelled crawler and wheeled loaders (as defined in ISO 6165). The third edition (2009) covers base‑machine classification, equipment and attachments, dimensional definitions, and performance terminology to ensure consistent specifications in technical documentation, sales literature and procurement.
Key topics
- Terminology and definitions: standardized terms for loader types (crawler, wheeled, compact, skid‑steer), components, masses (operating mass, shipping mass) and attachments.
- Base machine classification: undercarriage, engine location, steering systems (front, rear, all‑wheel, articulated, skid) and drive systems.
- Equipment & attachments: nomenclature and dimensional definitions for buckets, multi‑purpose and side‑dump buckets, scarifiers, forks, log grapples, winches and other common attachments (see Annex A for dimensions).
- Performance terminology: net engine power, tipping load, rated operating capacity, breakout force, raising/lowering/dump times, maximum travel speeds, braking and turning performance.
- Commercial literature requirements: prescribed information to be included in sales and technical literature (SI units), including which characteristics can be affected by bucket, tyre or ballast selection (e.g., bucket capacity, operating height, tipping load).
- Normative references: cross‑references to related ISO test and measurement standards (for example, ISO 6165, ISO 6746, ISO 9249, ISO 14397‑1/2, ISO 3450, ISO 10265, ISO 7457, ISO 6014).
Applications
- Ensures consistent, comparable machine data in manufacturer brochures, technical specifications and datasheets.
- Supports accurate procurement decisions by contractors, rental companies and fleet managers who compare loader capabilities (tipping load, operating mass, breakout force).
- Aids technical writers, documentation teams, and marketing departments in preparing compliant commercial literature.
- Assists test laboratories and regulatory reviewers by clarifying performance terminology and reference methods.
- Useful for OEMs integrating attachments and for engineers specifying compatibility and dimensional clearances.
Who should use it
- Loader manufacturers and OEMs
- Technical authors and product marketing teams
- Equipment rental companies and fleet purchasers
- Test houses, compliance assessors and standards committees
- Engineers specifying earth‑moving equipment
