MarsMetal
Damper Weights Mars Metal damper weights work to counteract the effects of vibration. Vibration, as perceptible mechanical vibrations can be generated by many sources: Transportation sources such as subways. Heavy truck traffic or streetcars. Machinery in buildings such as HVAC units. People in buildings such as dancing, aerobics, chanting or cheering. Even the wind can cause buildings to sway. These vibrations can generate unwanted structure-borne sound, and in severe cases can cause damage to the structure... (read more)Browse Counterweights Datasheets for MarsMetal -
Enidine Inc.
Viscous Dampers & Seismic Dampers Viscous dampers (also known as seismic dampers) are hydraulic devices that dissipate the kinetic energy of seismic events and cushion the impact between structures. They are versatile devices that can be designed to allow free movement as well as controlled damping of structures to protect them from wind load, thermal motion, or seismic events. Our seismic dampers are well-suited for large displacement and/or large load applications such a bridges, buildings, and other large structures...
