Overview
ISO 6405-2:2017/Amd 1:2022 is an important amendment to the international standard for earth-moving machinery symbols. Developed by the International Organization for Standardization (ISO), this amendment adds new graphical symbols for operator controls and display indicators used in various types of earth-moving equipment, accessories, and related machinery. By implementing these updated and additional symbols, manufacturers, operators, and maintenance personnel worldwide can benefit from clearer, more consistent communication across equipment types and brands, supporting safety and efficiency on job sites.
This document is part of the ISO 6405 series, which standardizes operator control symbols to facilitate recognition, reduce training time, and lower risks associated with machine operation.
Key Topics
- Updated Symbol Set: The amendment introduces new symbols, specifically for track-type machines, graders, excavators (including cable and hydraulic types), loaders, and drills.
- Enhanced Operator Interface: New graphical symbols enable easier identification of controls and operational statuses, benefiting training, safety, and maintenance.
- International Consistency: The additional symbols are referenced within the ISO/IEC 7000 database, ensuring harmonized understanding and use globally.
- Symbol Categories:
- Track-type machinery and directional track controls
- Grader blade operations, including float positions for left, right, and overall blades
- Excavator controls for swing (left/right) and upper structure identification
- Cable excavator dipper operations (raise, lower, extend, retract)
- Loader bucket identification and operational controls
- Drill system operations, including drill bit controls, oil, mode indicators, and automation features
Applications
The symbols established in ISO 6405-2:2017/Amd 1:2022 are intended for practical use in the earth-moving machinery sector, including but not limited to:
- Operator Controls: Enhancing clarity on control panels of excavators, graders, loaders, and drills by using intuitive, standardized visual symbols.
- Visual Displays and Indicators: Providing clear operator feedback on machine status, such as blade position, track movement, or drill automation mode, through graphical indicators.
- Training and Documentation: Facilitating training and onboarding of operators by using universally recognized symbols, reducing language barriers and misunderstanding.
- Manufacturing and Maintenance: Assisting manufacturers and service professionals in creating consistent operator manuals and equipment labels that comply with international standards.
- Health and Safety: Minimizing the risk of operator errors that could cause accidents or equipment damage, through improved symbol recognition and reduced ambiguity.
Related Standards
ISO 6405-2:2017/Amd 1:2022 connects to several other important standards in the field, including:
- ISO 6405-2:2017: The main document for earth-moving machinery symbols, covering specific machines, equipment, and accessories.
- ISO 7000: Graphical symbols for use on equipment (the database where symbol registration numbers referenced in this amendment are maintained).
- ISO/IEC 80416 series: Standards covering basic principles for graphical symbols for equipment.
- IEC/ISO 60417: Symbol standardization for electrical equipment, relevant for machinery with electrical interface elements.
These related standards provide a comprehensive framework for graphical symbols, supporting consistent equipment operation, safety, and maintenance across the global earth-moving and construction industries.
