Lighting Tower Specifications
The figures below describe typical industry specifications for this class of equipment rather than a single fixed model. Use them to scope a requirement, then confirm exact figures against the supplied unit before purchase.
| Specification | Typical value |
|---|---|
| Mast height | 7–9 m typical; 12 m available |
| Lamps | 4 × LED 200–500 W, or 4 × metal halide 400–1000 W |
| Illuminance | Design for 20–50 lux on haul roads, 50–100 lux on working pads |
| Coverage | Roughly 3,000–6,000 m² per tower at working lux |
| Generator | 6–12 kVA diesel, 400 V or 230 V |
| Runtime | 50–150 h on a full tank, LED at the long end |
| Fuel consumption | 0.5–1.5 L/h LED; 1.5–3.0 L/h metal halide |
| Mast | Manual or hydraulic, with wind rating and auto-stow on some models |
| Trailer | Road-towable, outriggers, on-board bunded tank |
What a Lighting Tower Is Used For
- Night-shift pit loading and dumping
- Plant and crusher night maintenance
- Concrete night pours
- Exploration camp and drill pads
- Emergency lighting after a power cut
Maintenance Schedule
Most premature failures in this equipment class trace back to a missed routine check rather than a design fault. The intervals below are a practical starting schedule; adjust them to your duty cycle and the manufacturer manual.
| Interval | Task |
|---|---|
| Every shift | Check fuel, outriggers, mast pins and that all lamps are firing; confirm the bund is empty of rainwater. |
| Daily | Engine oil and coolant on long-run units; inspect cables and mast sheaves. |
| 250 h | Engine oil and filters; inspect hydraulic mast cylinders where fitted. |
| Annually | Load-test the generator; inspect mast welds and trailer brakes; replace lamps as a set if output has dropped. |
Frequently Asked Questions
LED or metal halide?
LED. Fuel use is roughly half, lamps last many times longer, they start instantly (no cool-down), and they tolerate voltage dip from a small generator. Metal halide is cheaper to buy and still common, but on a Tanzanian night shift the fuel saving pays for LED quickly.
How many towers does a pit need?
Enough that working areas meet a design lux level, not “it looks bright from the office.” As a starting point, one tower per loading face plus one on the dump and one on the pad. Shadows behind machines are where people stand. Place towers so operators are not looking into the lamps.
Can I just use vehicle headlights?
No. Headlights move, glare, and leave the rest of the pit dark. Almost every night-shift collision and fall on a small mine happens in the dark patch just outside a headlight beam. Designed lighting is a production tool as well as a safety one — cycle times improve when the dump is actually visible.
