Below-the-Hook Lifting Devices
Purpose of ASME B30.20-2025
The main purpose of ASME B30.20 is to establish essential safety criteria for devices that fall between the hoist hook and the load, ensuring the integrity of the connection and the safe handling of the material. This standard focuses on components that are engineered and fabricated for specific lifting tasks where traditional slings or hooks alone are inadequate or inefficient.
The standard covers the technical provisions for the:
The 2025 revision notably clarified and expanded requirements for Load Containing Lifting Devices (like crane skip pans or certain material bins), emphasizing that these containers must be properly rated and constructed to maintain the safety chain from hook to load.
What is it Used For?
ASME B30.20-2025 is essential for manufacturers, owners, operators, and maintenance personnel of these highly specialized lifting attachments. It is used in construction, manufacturing, and shipping industries where unique or large objects must be lifted. The standard covers six main types of devices:
Users must typically apply this standard in conjunction with ASME BTH-1 (Design of Below-the-Hook Lifting Devices), which provides the specific structural and mechanical design criteria that B30.20 enforces for manufacturing and safe operation.
