ISO 9928-1:2015 Crane Operation Manual Guidelines Explained

Manual Content Framework

ISO 9928-1:2015 sets out a systematic content framework for operation manuals. The manual must include the following sections: Foreword and Scope (purpose, applicable crane models, manual version number, and date of issue); Safety Instructions (general safety rules, specific hazard warnings, and operating restrictions); Technical Specifications (key technical parameters table, structural diagrams, and working range diagrams); Transport and Installation (transport requirements, lifting plan, and installation & commissioning steps); Operating Instructions (control device descriptions, operating procedures, lifting operations, and special working conditions); Maintenance (daily inspection items, periodic maintenance intervals, lubrication chart, and wear parts list); Fault Elimination (common fault symptoms, probable causes, and remedies); and Disposal (end-of-life conditions and environmental requirements).

The standard requires that manual sections follow a logical sequence from general to specific. Each section must have a clear title and a numbered system using Arabic numeral grading, with continuous page numbering and the total page count indicated at the bottom of each page. Warnings, cautions, and notices must be formatted consistently—warnings on red backgrounds, cautions on yellow, and notices on blue—so they are immediately recognizable and uniform throughout. The standard also specifies a numbering convention for figures and tables, with sequential numbering applied separately to each.

Format Requirements for Manual Preparation

The standard specifies the physical format of the manual. The recommended page size is A4 (210×297 mm) or A5 (148×210 mm); for thicker manuals, a master table of contents and section-level tables of contents should be provided. The text must be prepared in bilingual Chinese-English (for export equipment, an official-language version for the target market should be added). Chinese text should use SimSun or SimHei, and English text Arial or Times New Roman. Body text height must be ≥3 mm (no smaller than 9 pt). Technical terminology must conform to the definitions in the ISO 4306 series, and the first occurrence of each term should include both the Chinese and English equivalents along with a brief explanation.

Quality requirements for graphics and tables—technical drawings must clearly indicate dimensions and parameters, and photographs must accurately reflect the actual equipment. Wiring and piping diagrams should use different colors or line types to distinguish between systems. The operating direction symbols for control devices must follow the directional indicators specified in ISO 21455:2018. All figures and tables must be numbered, indexed, and referenced in the body text. The standard also requires an equipment identification block on the front cover and inside front cover, listing the manufacturer's name, equipment model, serial number, manual version number, and date of issue. The manual version number must be kept in sync with the equipment's technical change version.

Language and Readability Requirements

The standard emphasizes readability and ease of use for operation manuals—language should be concise and precise, avoiding ambiguity, and technical terms should be defined at first mention. Operating procedures should use imperative sentences and numbered sequences (e.g., ① Turn on the power supply ② Check the Emergency Stop Button ③ Preheating run for 3 min), with each step containing a single independent action. Warnings and safety notices should use prominent symbols and formatted text boxes—the warning symbol indicates risk of personal injury, the caution symbol indicates risk of equipment damage, and the notice symbol ℹ indicates important operating tips.

The standard also requires a quick-reference index in the manual—the inside cover should feature an emergency operation quick reference table (key actions for emergency stop, manual release, and fault handling), and the appendix should include a keyword index (sorted alphabetically, with page numbers for each term). The manual should provide a QR code linking to the electronic version (PDF format, viewable and downloadable online), which must match the printed version and be updated in synchronization. Kelude Heavy Industry's product manuals are compiled in strict accordance with ISO 9928-1:2015, bilingual Chinese-English, and include a QR code for the electronic version.

Update Management and Version Control

The standard sets requirements for manual updates and management—the manual version number should be linked to the equipment's technical change version. The manual must be updated whenever the equipment undergoes any of the following changes: structural or functional modifications, safety device updates, maintenance requirements adjustments, or standard/regulation revisions. Each update should be recorded in the version history table on the cover page, including the update date, summary of changes, and version number. After a manual is updated, obsolete copies should be collected and destroyed or marked as void.

Manufacturers must provide users with a manual update notification service—publishing update announcements on the official website or service platform and notifying registered users via email or SMS. Users should obtain the new version of the manual within 30 days of receiving the update notice. Kelude Heavy Industry offers a lifetime manual update service for users, delivering one printed copy and one electronic version of the manual with each equipment shipment.
