REQUESTS FOR INTERPRETATION The B30 Standards Committee will render an interpre- tation of the provisions of the B30 Standard. An Interpretation Submittal Form is available on ASME’s website at http://cstools.asme.org/Interpretation/ InterpretationForm.cfm. Phrase the question as a request for an interpretation of a specific provision suitable for general understanding and use, not as a request for approval of a proprietary design or situation. Plans or drawings that explain the question may be submitted to clarify the question. However, they should not contain any proprietary names or information. Read carefully the note addressing the types of requests that the B30 Standards Committee can and cannot consider. Upon submittal, the request will be forwarded to the relevant B30 Subcommittee for a draft response, which will then be subject to approval by the B30 Standards Committee prior to its formal issuance. The B30 Standards Committee may rewrite the question for the sake of clarity. Interpretations to the B30 Standard will be available online at https://cstools.asme.org/Interpretation/ SearchInterpretation.cfm. SECTION X: ADDITIONAL GUIDANCE The equipment covered by the B30 Standard is subject to hazards that cannot be abated by mechanical means, but only by the exercise of intelligence, care, and common sense. It is therefore essential to have personnel involved in the use and operation of equipment who are competent, careful, physically and mentally qualified, and trained in the proper operation of the equipment and the handling of loads. Serious hazards include, but are not limited to, improper or inadequate maintenance, overloading, drop- ping or slipping of the load, obstructing the free passage of the load, and using equipment for a purpose for which it was not intended or designed.
dogleg, severe: a permanent, localized, irreparable bend or deformation in a wire rope that restricts the natural adjustment of the rope’s components during operation due to strand distortion. It is caused by improper use or handling and results in an indeterminate loss of strength in the rope (see Figure 30-0.2-4). fiber core: a wire rope center component consisting of man-made or natural (vegetable) materials whose purpose is to support the outer strands of the wire rope and is not included as one of the load-bearing compo- nents of the wire rope when calculating the minimum breaking force. fleet angle: the angle between the rope’s position on a drum or sheave and the line drawn perpendicular to the axis of the drum or sheave through the center of the nearest fixed sheave (see Figure 30-0.2-5). groove corrugation: a repetitive pattern in the groove of a sheave or drum caused by wear at the contact point with each rope strand that may cause rope wear and distortion. guy: a fixed length of strand or rope for stabilizing or main- taining a structure in a fixed position or a constant distance between the two components connected by the rope. heavy rope service: service that involves operating at 85% to 100% of rope rated load or in excess of ten lift cycles per hour as a regular specified procedure. high modulus polyethylene (HMPE): a polyolefin fiber produced by gel spinning or solid-state extrusion of an ultra-high-molecular-weight polyethylene (UHMWPE) feedstock to produce extremely high tenacity [also known as extended-chain polyethylene (ECPE) or high- performance polyethylene (HPPE)]. hours of rope operation: the actual or estimated operating time of the rope. hybrid rope: a wire rope consisting of both synthetic and steel components. The synthetic components are included as load-bearing components of the rope when calculating its minimum breaking force.splice: the joining of two ends of yarn, strand, or cordage by intertwining or inserting these ends into the body of the product. An eye splice may be formed by using a similar process to join one end into the body of the product. standard wire rope: stranded wire rope, the design of which is not intended to reduce load-induced torque (also known as non-rotation-resistant wire rope). standing rope: see guy. stay rope: see guy.
