  • Patent number: 7743596
    Abstract: A fire resistant rope and method of making the same. The fire resistant rope comprises a core, a jacket, and a fire retardant coating. The core comprises a plurality of strands. Each core strand comprises a plurality of core yarns, and each core yarn comprises a plurality of high tensile strength fibers. The jacket comprises a plurality of jacket strands. Each jacket strand comprises a plurality of jacket yarns and each jacket yarn comprises a plurality of high temperature resistant fibers. The fire retardant coating formed on at least one of the core and the jacket. The fire retardant coating expands when subjected to temperatures above a state-change level. At least a portion of the expanded coating inhibits transfer of heat to the core. The state-change level is below a failure temperature defined by the materials from which at least some of the fibers forming the core are formed.

  • Patent number: 7437869
    Abstract: A fire resistant rope and method of making the same. The fire resistant rope comprises high tensile strength fibers, high temperature resistant fibers, and a fire retardant coating. The fire retardant coating is applied to at least one of the high tensile strength fibers and the high temperature resistant fibers. The high tensile strength fibers are combined to form a core. The high temperature resistant fibers are combined to form a jacket that at least partly covers the core. The jacket is configured to inhibit movement of air to the core. The coating is configured to inhibit movement of air to the core.
