lity assurance program equivalent to the applicant’s or licensee’s quality assurance program should be applied to the design, fabrication, installation, and initial testing of the crane. The scope of the quality assurance program should encompass those components defined in Section 2000, “Quality Assurance,” of ASME Std. NOG-1 for a Type I crane. b. The crane runway is outside the scope of ASME NOG-1, and therefore, the adequacy of the runway structure to support the transmitted load for the load combinations included in the crane design should be confirmed, consistent with the facility design basis for structures important to safety. Regulatory Position C.3 3. This RG endorses the guidelines of Chapters 1 through 3 of ASME Std. BTH-1-2017 for design and fabrication of special lifting devices and load attachment points that form a mechanical load path from the load to the crane hook (or other designed attachment point) and are used as part of an enhanced reliability handling system. The specific design criteria are subject to the following clarifications: a. Design Category B applies to lifting devices configured to provide two independent load paths between the load and the crane attachment points in a manner such that each load path can independently hold the load in a stable configuration. b. Design Category C applies to lifting devices configured to provide a single load path between the load and the crane attachment point. c. Load attachment points for both standard lifting devices and special lifting devices should be designed to Design Category B criteria for two independent load paths and Design Category C criteria for single load path configurations.
