BEKA Schréder has supplied an LED light- ing solution to upgrade the boom and machine house lighting on an Anglo American Coal dragline. Due to the machine’s excessive vibrations and the fact that it is continuously operational, ease of maintenance at long maintenance intervals was an important requirement LED lighting solution for dragline for this lighting project.

136 W floodlights were installed. All the necessary specified lighting level requirements were achieved in all areas. In such harsh environments as mines, BEKA Schréder’s LED luminaires offer a range of benefits over traditional indus- trial and floodlight luminaires. These include energy efficiency, a long useful operating lifespan with low maintenance requirements, surge protection and resis- tance to impacts and excessive vibrations. To ensure long lasting performance, elec- tronic temperature monitoring prevents overheating of LEDs and power supply (ThermiX®). Additionally, the units are designed for easy technology upgrade. The luminaires supplied for this project all have a housing made from high-pres- sure die-cast aluminium to ensure the luminaires’ long lasting performance, even when exposed to extremely harsh environments. BEKA Schréder locally develops and manufactures LED lighting products designed for local conditions. Beka Schréder, tel (+27 11) 238- 0000

BEKA Schréder proposed an LED light- ing solution due to the clear benefits of LED technology. Sixteen OMNIstar 322 W high-power LED floodlights replaced the boom’s sixteen 1 000 W high-pressure sodium floodlights. BEKA Schréder man- aged to achieve the required lighting levels, despite the lower wattage. The OMNIstar offers a real alternative to luminaires equipped with high-power traditional light sources, with the added advantages of an LED solution: low energy consumption, improved visibility with a colour temperature close to daylight, lim- ited maintenance and longer life. The boom is 100 m long, 19 m wide, with a tip height of 62 m, and is installed at an angle of 39 deg. The machine house lighting was also upgraded. The LEDnova 85 W LED industrial bulkhead replaced the 150 W high-pressure sodium bulkhead inside the machine house. On the exterior, LEDflood

OMNIstar LED floodlights illuminate the pit area.
