ASME A17.6-2010 pdf free.Standard for Elevator Suspension,Compensation, and Governor Systems. Rope Cores. Central elements, usually of fiber or steel around which the strands are helically laid. Rope cores shall have a rope manufacturer-specific identification marker incorporated during core manufacture or during closing of finished rope. The marker shall be of filament, fiber, or ribbon material. See Fig. Fiber Core (FC). An element made from either natural or synthetic fibers.
1, Independent Wire Rope Core (IWRC). A core constructed as a round stranded steel wire rope. The core and/or its outer strands may also be covered or filled with either fiber or solid polymer. Solid Polymer Core. A single element ol solid polymer material that is either cylindrical or shaped (grooved). It may also include an element or elements of wire or fiber. LubricatIon Rope Lubricant. A material applied during the manufacture of a strand, core, or rope in elevator systems, reducing internal friction and/or providing protection against corrosion. Impregnating Compound. A material used in the manufacture of natural fiber cores for the purpose of preserving fiber integrity in service and pro. viding protection against rotting and decay of the Fiber material.
1.3.2 Descriptions of Elements Specific to Rope Assemblies Rope Types Stranded Rope. An assembly of several strands layed helically around a core.
(a) Single Layer. Rope consisting of one layer of strands laid helically around a core.
(b) Corn pactrd Strand. Rope in which the strands, prior to closing of the rope, are subjected to a compacting process such as drawing, rolling, or swaging.
(c) Mullilaen’d. Ropes consisting of multiple layers of strands laid helically around a core. Rope Classification and Construction Rope Classification. A grouping of ropes of similar characteristics on the basis of, for stranded ropes, the number of strands and their shape, the nominal number of wires in one strand, the actual number of outer wires in one strand, and the actual number of wire layers in one strand. For classification details refer to Tables 1-1.1-1, 1-1.1-2, 1-1.1-3, and 1-1.14. Rope Construction. The detail and arrangement of the various elements of the rope, taking into account the number of strands and the number of wires in the strand. For designation details refer to Tables 1—1.1-1, 1—1.1—2, 1—1.1.3. and 1-1.1-4.
NOTE: Rope construciion is designated by listing the number of outer strands followed by the number of wires in each strand and the designation for the type of construction, e.g.. 6 x 25F. The “x” symbol is read as by7 Rope Grade. A level of requirement of breaking force that is designated either by a number (e.g., 1570, 1770) or historical grade designations (e.g., Traction, Extra High Strength). See 1.6.3.
NOTE: Rope grade does. not imply that the actual tensile strength of the wires in the rope are necessarily of this grade as multiple wire grades can be used in the s.me rope.ASME A17.6 pdf free download.
