GB/T 17909.1-1999 Crane Operating Manual Requirements
ISO 9928-1:1990 (GB/T 17909.1-1999) — Crane Operating Manuals — Part 1: General Principles is the governing standard for preparing crane operating manuals. The standard specifies the content, format, and preparation requirements for operating manuals, serving as the common basis for manufacturers writing operating instructions and for users following standardized operating procedures.
GB/T 17909.1-1999 is the Chinese national standard equivalent to ISO 9928-1:1990, dedicated to the preparation of crane operating manuals. The operating manual is one of the most critical pieces of Accompanying Documentation delivered with a crane at handover. It serves as the operator's primary guide for correct equipment operation, preventing misuse, and responding to emergency situations. The standard is applicable to operating manuals for overhead type, gantry type, tower type, mobile type, and other crane configurations. It defines the content framework and writing specifications that the manual must follow.
Core Content of the Operating Manual
The standard specifies that the operating manual must include the following core sections. The overview section covers the crane Model, Specification, manufacturer name and address, Serial Number, date of manufacture, applicable Standard numbers, and a Technical Parameters summary table (Rated Lifting Capacity, Span, Lifting Height, Work Duty / Classification, Power Supply parameters, etc.). The safety section covers safety precautions and safety sign explanations, including operating prohibitions (no overload, no angled lifting, no lifting of unidentified loads, etc.), descriptions and setpoints of safety devices (Overload Limiter trip values, Limit Switch positions, wind speed alarm thresholds, etc.), personal protective equipment requirements (hard hats, anti-slip shoes, protective gloves, etc.), and emergency operation procedures for emergency situations (power loss, Manual Brake Release, emergency Lowering, etc.). The safety section must be placed at the very front of the manual, highlighted with bold text and safety warning symbols.
The operating section provides detailed operating procedures for each mechanism, including the layout and function of the Controller or Control Grip, step-by-step operating procedures for each mechanism (complete startup, running, and stopping sequences), restrictions on simultaneous operation of two mechanisms (Hoisting / Lifting and travel must not be operated at the same time), and proper use of Speed control devices along with Micro-motion operating skills. Operating procedures must be presented in numbered steps, with each step beginning with an action verb for clarity and conciseness. The maintenance section covers Daily Inspection items and inspection intervals, a Lubrication Chart (identifying each lubrication point, lubricant grade, and Lubrication Interval), adjustment methods and parameters for each mechanism (Brake clearance, Coupling shaft alignment, Wire Rope deflection angle, etc.), and a Wear parts list with Replacement Intervals. The appendix includes the Electrical Schematic and wiring diagram, hydraulic system and pneumatic system schematics, a common faults troubleshooting comparison table, and after-sales contact information.
Format and Language Requirements
The standard sets normative requirements for the format and language of the operating manual. The manual must be printed on A4 paper (210mm × 297mm), and the binding method should prioritize ease of use (spiral or loose-leaf binding is recommended for flat opening and partial page replacement). Page numbers must be consecutive and the total page count must be indicated. The cover must include the equipment Name and Model, manufacturer name, and document number. The manual must be written in Chinese (export equipment may include additional language versions, but the Chinese version retains equal legal effect). Content must be accurate and concise, avoiding dialects, slang, or ambiguous wording. Safety warnings must use standardized safety warning symbols: Danger (red background with white symbol) — indicates a hazard that will result in death or serious injury if not avoided; Warning (orange background) — indicates a hazard that could result in death or serious injury if not avoided; Caution (yellow background) — indicates a hazard that could result in minor injury or equipment damage if not avoided.
Illustrations and tables are essential components of the operating manual. The standard requires that all illustrations and tables be numbered with corresponding captions. Illustration numbers follow chapter order (e.g., "Figure 3-1 Controller Layout"), and table numbers follow chapter order (e.g., "Table 5-1 Lubrication Schedule"). Illustrations for operating procedures should use three-dimensional diagrams or photographs, with key operating components labeled by position and number. Electrical Schematic diagrams must use national standard graphical symbols (GB/T 4728 series), with component numbers and wire numbers marked on the diagram. The Lubrication Chart should mark each lubrication point number, lubricant grade, and lubrication interval on an overall machine outline diagram. All illustrations must be clearly legible, with photo Resolution of no less than 300dpi. Drawings and tables should be neatly folded and attached at the back of the manual for easy removal and enlarged reference.
Operation Manual Management Requirements
The standard also specifies management requirements for the operation manual. Each crane shall be equipped with no fewer than two copies of the operation manual at the time of factory delivery—one set delivered with the equipment to the user unit, and one set retained by the manufacturer for archival purposes. The manual shall be kept in a dedicated document box located in the cabin or near the equipment, and must not be left loose or removed from the equipment site. A version management system shall be established for manual revisions and updates—each revision shall be documented in a modification record sheet noting the nature of the change, the reason for it, the person responsible, and the date. Revised versions shall carry a new version number and date. Superseded manuals shall be collected and destroyed or stamped as obsolete. After any retrofit or major maintenance work on the equipment, the user unit shall obtain an updated operation manual from the manufacturer.
The standard encourages manufacturers to also provide an electronic version of the operation manual, delivered on CD or USB drive alongside the printed copy. The electronic manual shall be in PDF format with full-text search and bookmark navigation. The Technical Specifications may also be provided as an Excel spreadsheet to facilitate import into the user's equipment management system. For exported equipment, the electronic manual shall include multilingual versions such as Chinese and English. The electronic manual shall be protected by password protection to prevent unauthorized modifications, with the modification password held by the manufacturer. Kelude delivers both printed and electronic versions of the operation manual at equipment handover, compiled according to the standard format.
Operation Manual Content Framework Comparison Table
The comparison table below summarizes the content framework and core requirements for each section of the operation manual as specified by the standard. Manufacturers can use this framework as a checklist when compiling the manual, and users can reference it during acceptance.
| Section | Main Content | Formatrequirements |
|---|---|---|
| Overview | Equipment Data/Technical Parameters/Implementation Standard | Tabulated Summary Parameter |
| Safety | Prohibited Operations/safety device/Emergency Procedures | Warning Symbols/Bold Type |

| maintenance | inspection/Lubrication/adjustment/Wear Parts | lubrication chart/adjustment Parameter Table |
| Appendix | Electrical Schematic/Troubleshooting Chart/Contact Information | Schematic Diagram/wiring diagram/Photograph |
Operation Manual Requirements for Specialized Crane Types
The standard imposes additional requirements on the operation manuals of specialized crane types. For tower cranes, the manual must include: procedures and safety precautions for tower mast jacking and lowering, installation and inspection requirements for each anchorage device, safe operating procedures for the tower mast in wind-power applications (operations must cease and the slewing brake must be released when wind speeds exceed Beaufort Force 6), and operating instructions and test methods for the load moment limiter (LML). For mobile cranes, the manual must cover: outrigger telescoping procedures and ground-bearing capacity requirements, rated load charts for various jib length combinations, and the transition procedures between traveling and lifting configurations. For overhead and gantry cranes, the manual must address: safety precautions for crane bridge and trolley travel, coordinated operating procedures for multiple cranes on the same runway, and the use of wind rail clamps and anchor devices.
FAQ: Common Questions About Crane Manuals
Q: What should I do if the operation manual is lost?
A: Contact the original manufacturer for a replacement. If the manufacturer is no longer in business, commission a qualified inspection agency to rewrite the manual based on the actual equipment condition, following the content framework and formatting requirements of ISO 4306.
Q: Does the operation manual need to be updated after a crane retrofit?
A: Yes. After a major retrofit or significant maintenance work, the relevant operating procedures, safety device parameters, and circuit diagrams may change. The operation manual must be revised accordingly to ensure operators always work to the latest version.
Q: Do operation manuals for imported cranes need to be translated?
A: Yes. Manuals kept at the crane site must be in the local language. For imported equipment, the manufacturer or importer must provide a translated version, which must be reviewed and approved by the technical manager before use.
Q: Are the operation manual and maintenance manual the same document?
A: No. The operation manual is intended for operators and focuses on daily operation and safety precautions. The maintenance manual is intended for service personnel and covers disassembly, reassembly, fault diagnosis, and parameter commissioning. The two may be combined into one document, but the applicable subjects and chapter divisions must be clearly identified.
