High-output six-head vertical mast tower
A vertical-mast tower carrying six heads instead of four, for large open areas — quarry benches, laydown yards, stockpiles — where one tall unit replaces several small ones.
Features
- Six heads on a taller mast cover substantially more area per unit, which cuts the number of units and the transport with it.
- The heads are usually aimable in pairs, so the unit can light 360 degrees around itself or throw everything one way.
- Higher masts raise wind loading, so the wind speed at which the mast must be lowered is typically lower than on a 7 m unit.
- Larger outrigger footprint is needed, which makes this the wrong unit for a lane closure and the right one for open ground.
- Engine and alternator are larger to carry six heads, so run time per fill is shorter than a four-head unit on the same tank.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Heads: number × rating | 6 × 320 / 6 × 500 | W | Sets total output and aiming options. |
| Total luminous flux | 280 000 - 440 000 | lm | One unit may replace two smaller towers. |
| Mast height, extended | 9.0 - 12.0 | m | Needed to spread six heads' output. |
| Maximum wind speed, mast raised | 60 - 70 | km/h | Lower than a short mast; plan for lowering. |
| Outrigger footprint (L × W) | 3 000 × 2 600 | mm | Rules it out of confined positions. |
