Permanent Lighting in industrial environment with strong vibration

Bindu

Good morning everyone,

are there any suggestions on installation of permanent lighting in areas with strong vibration?

In particular, I am searching for adequate installation methods on walkways above fans in the cooling condenser areas. Fans are responsible for strong vibration all year round, the whole steel structure is shaking and traditional bracketry seems to fail at fast rate.

Consider that the walkway to be illuminated has a handrail on both sides but no other structural steel or walls are available because the roof can't be used for lighting support.

Kind regards

    I probably have the wrong picture, but could the walkway handrails support a few arches perhaps? lights on short chains are then a common solution to a vibration problem, but screw terminals can still be an issue. Mind you I'm intrigued as to what sort of bracket fails, if the walkway does not.  Though I can imagine long cantilever supports suffering rather like a wobbly diving board.
    It may be worth looking at the sort of lights used on armoured vehicles and farm tractors and similar

    Brackets failing are the ones coming with the light fittings. Any cantilever and unistrut attached to the walkway/handrails are generally resistant (although vibration increases the longer they become in particular if lighting is installed on ca. 2 meters high unistrut structure). 

    Most typical accident would be the light fitting to fall on the walkway while the supporting unistrut stands there and wobbling.

    I have seen some areas where additional ties were put around the light fitting as additional support and I'd like to avoid this in the future because it's not really state of the art.
