The device belongs to the class of tuned-mass dampers and consists of a mass connected to the structure by steel or super-elastic wire ropes. When the structure to be protected is excited, the kinetic energy is transferred to the mass of the device that oscillates with respect to the structure and applies on it a restoring force that works to reduce its motion.
