I. Core Positioning of ASME B30 Standards: The “Universal Language” for Global Crane Safety
ASME B30, officially titled “Safety Standards for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings”, is formulated and continuously revised by the ASME B30 Committee under the American Society of Mechanical Engineers (ASME), which was founded in 1880. As an authoritative standard recognized by the American National Standards Institute (ANSI), its core mission is to prevent personal injuries and property losses in crane operations by clarifying technical requirements and management processes, providing a unified implementation basis for manufacturers, employers, users, and regulatory authorities.
The core value of this standard is reflected in three dimensions: first, global universality, which has been adopted by projects in North America, the European Union, and more than 100 countries around the world, serving as a “pass” for the international market access of crane equipment; second, full-life-cycle coverage, realizing the whole-process safety control from equipment design, manufacturing, and installation to daily inspection, periodic inspection, maintenance, and even scrapping; third, wide industry adaptation, covering multiple fields such as construction, manufacturing, energy, ports, and mining, and adapting to various application scenarios of crane machinery and slings.
II. Composition of the ASME B30 System: Overview of Core Volumes (with Application Scenarios)
The ASME B30 Series includes more than 30 independent volumes, each focusing on a specific type of crane equipment or component with clear targeting. The following are the commonly used core volumes in the industry and the latest version information, facilitating practitioners to quickly match their own needs:
| Volume Number | Standard Title | Core Content | Application Scenarios |

| B30.9 | Wire Rope Slings | Selection, usage specifications, wear inspection standards, and scrapping criteria for wire rope slings | Daily use and inspection of wire rope slings in various lifting operations |
| B30.10 | Hooks | Hook material requirements, strength verification, flaw detection standards, and defect handling procedures | Production and operation & maintenance of crane hooks and sling connectors |
| B30.18 | Stacker Cranes | Structural design, operation mechanism, and safety protection requirements for overhead stacker cranes | Stacking operations in the warehousing and logistics industry |
| B30.20 | Below-the-Hook Lifting Devices | Marking, design, inspection, and maintenance requirements for below-the-hook lifting devices, including safety specifications for positioning fixtures | Adaptation and use of below-the-hook lifting devices for various hoisting equipment |
| B30.27 | Concrete Placement Systems | Concrete pump boom structure, outrigger devices, and safe operation procedures | Concrete pumping operations in construction |
Note: Each volume of ASME B30 is regularly revised in accordance with technological development and industry needs. It is recommended to prioritize the latest version to ensure compliance. For example, the 2025 Edition of B30.3 replaces the 2019 Edition, imposing stricter requirements on the foundation stability of tower cranes; the 2024 Edition of B30.10 refines the technical indicators for hook flaw detection.
III. Key Technical Points of ASME B30 Standards: Core Grasp for Safety Compliance
The core of the ASME B30 Standards lies in avoiding safety risks through quantitative technical requirements. The following five key technical points are the core of compliance that practitioners must master:
- Design and Load Control: Clarify the calculation methods for rated load, dynamic load factor, wind load, and seismic load. Require that equipment design must meet the structural strength requirements under extreme working conditions to eliminate the hidden danger of “overload design”.
- Compulsory Configuration of Safety Devices: All crane equipment must be equipped with core safety components such as limiters, anti-fall devices, overload protection devices, and anti-collision systems, and the verification cycle must be clarified (e.g., monthly verification of overload protection, annual verification of limit devices).
- Classified Inspection and Maintenance: Divide inspections into three levels: daily inspection, periodic inspection (monthly/quarterly), and comprehensive inspection (annual). Clarify the inspection items and qualification standards for each level. For example, wire rope slings need to be inspected for wear daily and undergo a breaking test annually.
- Personnel Qualifications and Operation Specifications: Require that crane operators must have corresponding qualifications, clarify the operation permit process, signal command standards, and prohibited behaviors (such as prohibiting oblique lifting and overloading of objects) to reduce the risk of human error.
- Quantitative Scrapping Criteria: Formulate clear scrapping indicators for structural cracks, fatigue damage, corrosion degree, and deformation. For example, hooks with an opening degree exceeding 10% of the original size must be scrapped, and steel wire ropes with the number of broken wires reaching the specified quantity must be replaced immediately.
IV. Core Application Scenarios of ASME B30 Standards
The ASME B30 Standards run through the entire industrial chain of crane equipment. The following four scenarios are the core areas of its application and the most concentrated demand scenarios for practitioners:
1. Equipment Manufacturing Link
Manufacturers need to conduct product design and process verification in accordance with the requirements of the corresponding volumes. For example, the production of mobile cranes must comply with the load and stability requirements of B30.5, and the production of wire rope slings must meet the material and structural standards of B30.9. Products must pass compliance inspection before leaving the factory to ensure they meet the ASME B30 Standards in order to obtain market access qualifications.
2. International Project Bidding
When participating in the bidding of international engineering projects in North America, the European Union, etc., the bidder is usually required to provide compliance certificates that meet the ASME B30 Standards. For example, in wind farm construction projects, lifting hooks must meet the requirements of the 2024 Edition of B30.10, and providing compliance test reports can improve the winning rate.
3. In-Service Equipment Operation & Maintenance
Enterprises need to carry out daily operation and maintenance work in accordance with the requirements of each volume of ASME B30: for example, tower cranes need to conduct foundation inspections and attachment device verification in accordance with the 2025 Edition of B30.3, and hooks need to undergo regular flaw detection in accordance with B30.10 to ensure that the equipment is safe and controllable during service.
4. Cross-Border Trade Compliance
When exporting crane equipment to regions such as North America and the European Union, it is necessary to pass the ASME B30 compliance audit and provide a statement of conformity. For example, exported hydraulic jacks must meet the design and inspection requirements of B30.1, otherwise they will be prohibited from entering the local market.
VI. Frequently Asked Questions (FAQ): Quick Answers to ASME B30 Usage Doubts
Q1: Are the ASME B30 Standards mandatory?
In North America, as American National Standards, the ASME B30 Standards are incorporated into local occupational safety regulations and are mandatory implementation standards; in other countries, although not mandatory, international projects and cross-border trade usually take them as core compliance requirements.
