We offer a high-energy rope mount isolator that incorporates the use of a traditional helical wire rope isolator encased in a proprietary elastomeric compound. The stainless steel cable of the mount provides for rugged construction, while the elastomer provides additional damping and stiffness. This unique design results in a fail-safe mount with a higher stiffness and energy absorption capacity. The mount is readily scalable and performance easily tuned by varying the wire diameter, loop size, number of loops, and elastomeric properties. The HERM isolator has proven particularly strong in low natural frequency “soft deck” applications of 12-16 Hz, reducing output G’s to below 15G’s. Its sealed nature of construction also provides for easy NBC washdown.
