Crane lighting has requirements which exceed normal Floodlighting. The Floodlighting needs to be very robust as the Cranes are generally mobile. Constant vibration will weaken the lamps and very often standard Floodlights will simply fall apart after a relatively short period.
In addition, the electrical supply on a Crane can vary significantly causing more electrical stress and early failures. Because many Cranes are in Harbours and Ports, there is constant corrosion from the marine environment. This is compounded by extreme temperature variations in many parts of the World and also between night and day time temperatures.
The 2 main Ports in Dubai were relit with Heavy Duty 1000w Marine Floodlights to provide white light and high light levels. The crane lights were mounted on existing Container Cranes. The contrast between the old Floodlights and the new scheme was so great that the remaining Floodlights were also changed. The new Crane Floodlights have special anti-vibration protection and high tolerance against voltage swings, which is often an issue on Crane lighting units. These Robust Floodlights are designed for robust long life even in extreme temperatures. The Luminaire is the most heavy duty Product of its type on the market (to our knowledge).
These Crane lighting and Marine Floodlights are in use in many Marine areas including many UK locations including most of Portsmouth Harbour UK, Durban in South Africa, New York Port, New Zealand, Africa, and many of the Gulf States, etc.
