Industrial light towers are useful for widespread illumination over busy work sites. In rugged environments, such as construction sites, outdoor locations and coastal regions, the units are prone to persistent vibration.
For lighting poles and portable light masts, sources of vibration include strong winds, exposure to heavy-duty equipment and nearby moving vehicles (for roadside construction projects). To address this issue, operators may utilize vibration dampeners to protect the lighting structure.
What is a Vibration Dampener?
A vibration dampener is a component found on poles, which absorbs vibration resulting in decreased structural fatigue. Compared to revamping the design of the pole, installing a vibration dampener on an existing pole is considered to be less costly. The lighting components can be field installable (very economical) or factory installed.
In addition to installing a vibration dampener on industrial light towers for construction sites and outdoor locations, operators can also select specific pole shapes that are capable of withstanding winds and persistent shaking. A round pole is considered to be more reliable against vibration than square poles.
Lighting poles should also be maintained and inspected properly for signs of degradation or structural fatigue.
Vibration Dampeners for Light Masts
There are several types of vibration dampeners for light towers and poles, such as chains, snakes, stockbridge dampers and canisters. The first three options are field installable, while the last one (canister) requires factory installation.
A chain-based vibration dampener is installed on the pole and sways naturally, based on the amount of vibration in the area. Shaking is decreased when the component comes in contact with the shaft (inside). A major drawback with using a chain-based dampener is noise.
Lastly, a factory-installed canister for industrial light masts is a set of disks that counteract the effects of vibration. Installed inside the pole, the components are compact and discreet.
