MODERN MINING
February 2016
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.
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.
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.
