“Anti-vibration and spring hangers are mechanical devices used to isolate and reduce the transmission of vibrations and noise in various engineering applications. They are commonly used in HVAC (heating, ventilation, and air conditioning) systems, industrial machinery, pipework, and other equipment that generate vibrations. These hangers help to enhance the overall performance, safety, and comfort of the system or structure by preventing excessive movement and noise.
Anti-vibration hangers:
Anti-vibration hangers are designed to minimize the transmission of vibrations from equipment or machinery to the building structure. They typically consist of a combination of rubber or neoprene isolators, steel springs, or other flexible materials. The hangers suspend the equipment, acting as a barrier between the equipment and the structure to dampen the vibrations.
Applications:
HVAC systems: They are used to support and isolate air handling units, chillers, pumps, and fans to reduce vibration and noise transfer to the building.
Industrial machinery: Anti-vibration hangers are used to isolate heavy machinery like generators, compressors, and motors to prevent their vibrations from affecting other components or workers.
Suspended ceilings: They can be used to isolate suspended ceilings in offices or commercial spaces to reduce noise transmission from floor above.
Spring hangers:
Spring hangers are used to support various systems and structures while allowing them to move vertically due to thermal expansion, seismic activities, or other dynamic forces. These hangers utilize helical steel springs that can stretch or compress to accommodate vertical movements.
Applications:
Pipework: Spring hangers are used to support pipelines and ducts in industrial settings to absorb thermal expansion or contraction, preventing excessive stress on the pipes.
Bridges: In bridge construction, spring hangers can be employed to allow vertical movement of the bridge deck in response to temperature changes or vehicular loads.
Power plants: Spring hangers are used to support equipment and pipes in power plants, where thermal fluctuations are common.
Both types of hangers are crucial in preventing structural damage, reducing noise levels, and ensuring the smooth operation of equipment and systems. They are chosen based on the specific application, load requirements, and the type of vibrations or movements that need to be isolated or accommodated. Properly installed and maintained anti-vibration and spring hangers contribute to the longevity and reliability of the supported systems or structures.”
