Whisper-Flex cable provides smooth operation at temperatures of –15° C to +60° C and, in the US, can be used for elevators with rated speeds of no greater than 700 ft/min ·3.56 m/sec (per ASME A17.1-2010, Rule 2.21.4.2 Compensating Rope Tie-Down).
Support brackets, U-bolts, S-hooks, and heavy duty stain-less steel grips specifically designed for Whisper-Flex cable must be used to ensure safe installations.
Damping devices are recommended to minimize cable sway for car speeds above 350 ft/min · 1.8 m/sec.
This diagram shows the approximate placement of components for a Whisper-Flex cable installation. Refer to the Compensation Cable Installation Guide for exact instructions on installation procedures.
