GB/T 17908 Crane Acceptance Standard Explained
GB/T 17908 "Crane Technical Performance Acceptance" is a key technical specification in the crane industry. Developed by the National Standardization Committee, it defines the acceptance criteria for crane technical performance.
The standard provides a unified technical basis for design engineers, inspection bodies, and end users. Kelude strictly adheres to its technical requirements throughout product development and manufacturing.
Scope and Application of the Standard
GB/T 17908 "Crane Technical Performance Acceptance" specifies the technical requirements for crane performance and applies to all types of lifting appliances with a Rated Lifting Capacity of 0.5 t and above. The standard covers not only the design and manufacturing of new equipment but also provides clear technical guidance for the inspection, maintenance, and modification of cranes already in service. It aligns with the EN 13001 Crane Safety Standard series and ISO 4309 Wire Rope Inspection Standard, forming a comprehensive technical specification framework. The clearly defined Technical Parameters and Safety factor requirements give design engineers a solid design basis, while also providing quantifiable acceptance criteria for third-party inspection bodies conducting Type Tests and Factory Acceptance Tests. As a critical component of the crane standard system, this standard works in coordination with the EN 13001 series and ISO 4309 to establish a complete technical specification framework.
Core Technical Parameters Framework
Under GB/T 17908, the design and manufacturing of cranes must meet a stringent set of Technical Parameters. These parameters are established based on extensive test data and safety engineering principles, covering everything from material selection to structural design.

| Report Sign-off | Inspection Personnel+Dual Sign-off by Customer Representative | Effective Report Legal Validity |
Inspection Requirements and Intervals
Factory Acceptance Tests are performed on each unit at the manufacturer's facility by the quality inspection department. Equipment that passes inspection is accompanied by a detailed inspection report and a Certificate of Conformity. For equipment in service, the periodic inspection interval generally does not exceed 12 months.

Safe Operation and Management Requirements
The standard places strong emphasis on operator qualification and training, requiring that all operators complete specialized training and obtain the necessary certifications before being allowed to operate the crane.
FAQ
Q: What types of acceptance are specified in the GB/T 17908 crane technical performance acceptance standard?
A: Factory Acceptance Test, Installation Acceptance, annual inspection, and acceptance after major repairs.
Q: What requirements does the GB/T 17908 standard set for static and dynamic load test methods on cranes?
A: Static load test at 1.25× rated capacity for 10 minutes; dynamic load test at 1.1× rated capacity for 3 cycles. Deflection and braking performance are measured during testing.
Q: What are the record-keeping requirements for crane inspection reports under the GB/T 17908 standard?
A: Inspection reports must be retained until the crane is decommissioned. Reports must include deflection data and the inspector's signature.
Q: What conditions must be met for a crane acceptance report to take effect under the GB/T 17908 standard?
A: The report becomes effective only after dual signatures from both the inspector and the customer representative. Once signed, the report carries legal weight.
