1. A device for isolating an object from external motions, the device comprising:
two wire rope isolators,
the two wire rope isolators being arranged such that, if one of the two wire rope isolators is loaded in compression, then the other wire rope isolator is loaded in tension,each of the two wire rope isolators comprising two retainer bars flexibly connected one to the other by at least one cable, linear guiding means allowing only for a relative displacement of some of the retainer bars with respect to the other retainer bars in a single direction, the direction being a common tension-compression direction of the two wire rope isolators, wherein at least one of the two wire rope isolators is at least one of a polycal wire rope isolator, a helical wire rope isolator or a a ring-type wire rope isolator. |
