ISO 6747:2013

Overview

ISO 6747:2013 - Earth‑moving machinery - Dozers - Terminology and commercial specifications defines standardized terminology and the content of commercial literature for self‑propelled crawler and wheeled dozers and their equipment. Published as the fourth edition in 2013 by ISO/TC 127 (Earth‑moving machinery, SC 4), the standard ensures consistent definitions and specification content used in technical documentation, brochures, product data sheets and procurement documents.

Key topics and technical requirements

ISO 6747:2013 organizes dozer information into clear, reusable elements. Key topics include:

• Terminology - precise definitions for terms such as dozer, base machine, equipment, attachment, component, dozing equipment and specific items (e.g., ripper types, winch types, swinging drawbar, ground reference plane).
• Masses - standardized mass definitions: operating mass (OM), shipping mass (SM), axle load and maximum axle load for wheeled machines.
• Performance metrics - definitions and testing references for net power, maximum travel speed, drawbar pull, static slope capacity (longitudinal/lateral), and winch performance (line pull/line speed).
• Base machine classification - classification by undercarriage (crawler vs wheel), steering system (articulated, pivot, skid/independent), and engine location (front/rear).
• Dimensions and nomenclature - standardized dimension definitions for base machines and attachments; Annex A contains dozer‑specific dimensions.
• Commercial literature content - required specification items for data sheets and brochures, covering engine, transmission, hydraulic system, fluid capacities, blade specification, masses, overall dimensions, and separate considerations for crawler and wheeled machines.

The standard references relevant test and definition standards (see Related Standards) to ensure measurement consistency.

Practical applications

ISO 6747:2013 is practical for:

• Manufacturers preparing product literature, spec sheets and marketing materials that must be internationally consistent.
• Procurement teams and fleet managers writing technical specifications or comparing dozer models.
• Engineers and designers ensuring component/attachment compatibility and correct dimensioning.
• Test laboratories and certification bodies using uniform terminology for reporting.
• Technical writers, translators and standards committees producing interoperable documentation for international trade.

Using ISO 6747 helps reduce ambiguity in commercial specifications, streamlines model comparison, and supports compliance with other equipment and safety standards.
