Crane Technical Performance & Acceptance Documentation Standard

GB/T 17908-1999, which is equivalent to ISO 9374-1:1989, provides a general framework for compiling crane technical and acceptance documentation. It applies to all documentation that manufacturers must supply with the equipment, including general arrangement drawings, technical specifications, installation and foundation drawings, electrical schematics, certificates of conformity, and operation and maintenance manuals. A standardized documentation structure streamlines the manufacturer's internal processes and ensures information symmetry for the user throughout acceptance, installation, and maintenance.

Technical Performance Document Content Requirements

The standard specifies that the technical performance document must include the crane's basic technical parameters, main structural parameters, and performance parameters for each mechanism. Basic technical parameters include: Rated Lifting Capacity (listed separately for main hook / auxiliary hook), Span (Track Gauge / Rail Gauge), Lifting Height (main hook / auxiliary hook), Work Duty / Classification (for the entire crane and each mechanism individually), Operating ambient temperature range, and Power Supply parameters (voltage, frequency, number of phases, capacity). Main structural parameters include: Main Girder section type, Total machine weight (including trolley and electrical equipment), Wheel load (Maximum Wheel Load and minimum wheel load), Rail type, and foundation load requirements.

Performance parameters for each mechanism must be listed separately: Hoisting mechanism – Lifting Speed (Full load / No-load), motor power and Rotational speed, Reducer / Gearbox Speed Ratio, Wire Rope diameter and length, Drum diameter and rope capacity; Long Travel / Bridge Travel mechanism – Travel Speed, motor power and quantity, Reducer / Gearbox Speed Ratio, Wheel Diameter and quantity; Cross Travel / Trolley Travel mechanism – Travel Speed, motor power and quantity, Reducer / Gearbox Speed Ratio, Wheel Diameter and quantity. Parameters for any Slewing or Luffing mechanism should also be listed. All parameters must be identified as either design values or measured values; for measured values, the measurement conditions and the accuracy class of the measuring instrument must be stated.

The standard also requires the technical performance document to include a dimensional outline drawing (General Arrangement Drawing). This drawing must show the overall dimensions (length × width × height), the distance between crane rails, the extreme hook positions (distance from the upper and lower limits to the rail surface), the Cabin / Operator Cab position, and the electrical control cabinet location. This drawing serves as the primary basis for the user's factory building design and equipment installation layout. The drawing scale must not be less than 1:50, all dimensions must be clear and complete, and critical dimensions must include Tolerance ranges. Kelude provides a complete set of general arrangement and detailed drawings with all technical parameters upon equipment delivery, compiled in accordance with GB/T 17908.

Acceptance Document Content Requirements

Acceptance documents are crucial for the user to confirm that the equipment meets the contract requirements and standard specifications. The standard specifies that these documents must include: the Product Certificate (with manufacturer's name, equipment name, Model and Specification, Serial Number, manufacturing date, applicable standard, inspection conclusion, and inspector's signature), the factory Inspection and Test records (including data and results from the No-Load Test, Rated Load Test (100% SWL), Dynamic Load Test, and Static load test), certificates of conformity for major purchased components (Motors, Reducers / Gearboxes, Brakes, Wire Rope, Bearings, etc.), and certificates of quality for main materials (mill certificates and chemical composition analysis reports for Steel Plate and structural sections).

Installation Acceptance documents must be completed by the user or the installation contractor after the equipment is installed and filed together with the factory documents. The Installation Acceptance documentation includes: foundation acceptance records (concrete strength, Embedded Part positions, Track Gauge / Rail Gauge, and Elevation), installation process records (assembly clearance for each mechanism, Coupling shaft alignment data, Bolt Tightening Torque, etc.), No-Load Test Run records (direction and speed of each mechanism, Limit switch activation points, and functional check of the Electrical Control System), and Load test records (progressive loading procedure, operational status of each mechanism, Brake slip / load drop, structural Deflection, etc.). The Installation Acceptance documents must be signed by both the installation supervisor and the user's representative.

Operation and Maintenance Manual Requirements

The standard specifies detailed requirements for the operation and maintenance manual, which must include the following sections: safety precautions (first-use safety warnings, operating prohibitions, and emergency handling procedures), installation and commissioning instructions (foundation and crane rail requirements, complete hoisting plan, installation steps for each mechanism, and electrical system wiring and commissioning methods), operating instructions (operation panel functions and operating procedures, operating methods for each mechanism, and standard startup and shutdown sequences), maintenance (daily inspection items and intervals, regular lubrication chart with recommended lubricating oil grades, and adjustment methods and parameters for each mechanism), troubleshooting (a comparison table covering common faults, possible causes, and troubleshooting methods), and the wear parts list (wear parts name, specification/model, and replacement interval).

The manual must be written in Chinese with clear, concise language and avoid ambiguous wording. Safety-related content must be highlighted in bold or marked with warning symbols. The lubrication chart must indicate the location of each lubrication point, the lubricant grade, and the relubrication interval. The electrical schematic must identify the model, specification, and terminal numbers of each component, while the wiring diagram must show wire numbers, gauges, and colors. Hydraulic and pneumatic system schematics must specify the function and adjustment parameters of each component. The manual must be securely bound for ease of reference, with drawings and tables neatly folded and attached at the back. Every page must be numbered with the total page count shown for completeness verification.

Delivery Document Checklist Comparison Table

The comparison table below lists the complete set of technical files and acceptance documents required by the standard. The manufacturer must provide every item on this checklist at the time of equipment delivery, and the user must verify and sign off on each item upon acceptance.

Document Management Requirements

The standard specifies that manufacturers must establish a management system for the preparation and control of technical and acceptance documents. All documents must be uniformly numbered and filed by category. The General Arrangement Drawing and Technical Specifications must be updated in synchronization with any equipment modifications, while superseded versions must be retained for future reference. Any document change requires a formal change notice detailing the reason for the change, the nature of the modification, and the affected document numbers, and the change may only be implemented after approval by the technical manager. Revised documents must bear a new revision number and the date of change, and obsolete versions must be stamped "VOID" and stored in a separate cabinet from current documents. Upon receipt of documentation, the user unit should verify that the latest revision has been supplied.

The standard also defines document retention periods. Factory documents and Installation Acceptance documents must be kept in the equipment technical documentation until the equipment is scrapped. The Operation and Maintenance Manual must remain with the equipment at all times during its service life for easy reference by operation and maintenance personnel. Waterproof, laminated copies of the Electrical Schematic and wiring diagram must be permanently fixed to the inside of the electrical control cabinet for use by electrical maintenance staff during on-site troubleshooting. In line with Digitalization efforts, manufacturers are encouraged to supply technical files in electronic form (on CD or USB drive) using universally compatible formats such as PDF or DWG. The Technical Specifications should also be provided as a spreadsheet file to facilitate import into the user's equipment management system. The user unit should back up all electronic files to prevent data loss.
