See pages 79 and 80 for details on this hardware. Draka EP dampening devices are recommended to minimize cable sway for car speeds above 350 ft/min (1.8 m/sec). See pages 81-83 for information on these devices. This diagram shows the approximate placement of components for a Whisper-Flex cable installation. Refer to the Compensating Cable Installation Guide for exact instructions on installation procedures. Draka EP can help you determine which size of Whisper-Flex cable to use. Call 1-877-372-5237 or +1-252-984-5100 and have the following information ready: 1) number of hoist ropes per car 2) outer diameter of the hoist ropes 3) stranding of the hoist ropes (i.e. 8 x19, 8x25...) 4) car roping (i.e. 1:1, 2:1, other...) 5) number of Whisper-Flex cables per car 6) length of Whisper-Flex cable needed *based on the most current code at the time of printing: ASME A17.1 2004, Rule 2.21.4.2 Compensating Rope Tie-Down Component Specifications Chain Low carbon, electrically welded proof coil chain. Each link is proof tested at two times the working load limit. Filler Metallic bead/polyvinyl chloride mixture adds mass and forms a round cross-section.
