41 t Tuned Mass Damper
WORLD RECORD for a 41 t Tuned Mass Damper installed on top of a 180 m concrete chimney suffering heavy vibration due to nearby structure – 5 viscous damper below the moving mass
Detail of 41 t Moving Mass
WORLD RECORD – detail of 41 t moving mass suspended by 16 pendulums on old cracked concrete of a 180 m concrete chimney, 5 viscous dampers sets placed below moving mass
Liquid damper used as a top platform
Liquid damper used as a top platform on a 100 m double skin steel stack – This stack is equipped of anti down wash system to protected the stack top form smoke plume and acid attack
TMD
TMD based on stainless steel coil. No wear withsand temperature from -50°C + 500 °C. Acid resistant
Tuned Mass Damper
Tuned Mass Damper (TMD) on top of a single flue stack – Damper set made by cable coils – no wear – maintenance free
Liquid Damper
Liquid damper use as a top platform during lifting on top of a 60 m double skin steel stack . Access to top by a manhole in the damper.
