Allmand Mine-Spec lighting tower

The Allmand Mine-Spec lighting tower has six 1250 W metal halide lamps on an adjustable head, powered by a 1.5 L Caterpillar engine driving a 15 kW generator. Built to withstand a range of arduous mining operating environments, the lighting tower features heavy-duty components, a 265 L fuel tank and can safety illuminate an area the size of one and a half tennis courts with a total light output of 900,000 lm.

The lighting tower uses a six-section, hydraulically actuated automatic lift mechanism to elevate the lamp head to almost 8 m above the ground. Intuitive adjustment of the lamp head allows accurate positioning of the lights before extending towers, with the tower able to be raised to its full height in 25 s. While the sectional tower is a typical design, both towers incorporate nylon guide sleeves which give smooth operation and help stabilise the tower when extended, enabling the unit to withstand wind gusts of up to 100 km/h. An integrated cable drum allows safe and neat extension and retraction of the power cable. The units are built in the US and comply with all Australian regulations and standards.

The company says the units have environmental fluid containment systems, battery isolation and emergency stop buttons as standard along with other options including fire extinguishers and auto start/stop controllers.
