The 2023 edition of ASME BTH-1 (Design of Below-the-Hook Lifting Devices) sets structural design requirements for lifting devices such as spreader bars, lifting beams, and frames. SDC Verifier provides a member check set based on selected provisions of ASME BTH-1:2023. The standard text is not included; engineers must use their own licensed copy for detailed requirements and interpretation.
The BTH-1:2023-based check set in SDC Verifier supports:
- Double-symmetric I-shapes
- Single-symmetric channels
- Circular and rectangular tubes
- Circular and rectangular bars
Member checks use geometric properties, bracing conditions, and design category assumptions as inputs.
ASME BTH-1:2023 continues the long-standing approach to safe design of lifting devices, with incremental refinements compared to the 2017 and 2020 editions. It is intended to be used alongside ASME B30.20, which addresses construction, marking, and operational practices. SDC Verifier implements the structural member checks; application of all relevant standards remains the responsibility of the engineering team.
Engineers can select the BTH-1 edition that best matches project specifications or compliance obligations. Final responsibility for meeting ASME requirements and any additional regulatory criteria lies with the engineer of record and the reviewing or certifying authority.
