DOOSAN Infracore Portable Power (DIPP) has launched the new V9 light tower with several innovative features that improve reliability and convenience, reduce fuel consumption and lower operating costs.
“Like all portable power products marketed under the brand name Ingersoll Rand, the V9 LightSource is built to withstand the rigours of everyday applications in the toughest conditions,” says George Schmalzried, public relations manager, Doosan Infracore International. “It provides advantages in plant hire, construction and roadwork projects as well as many other applications ranging from temporary lighting at the scenes of accidents, fires and other emergency situations to lighting at industrial sites, airports, warehouses and concerts and other events.”
According to Schmalzried, among the innovative features of the V9 LightSource is the electrical system, which has been designed so that components are electrically self-protected when the tower is switched off by the ‘emergency stop’ button rather than powered down as normal, using the key switch. As an option, the V9 features a unique energy-saving auto-start system with photocell and timer. In addition, the V9 offers an optional connection to mains electricity, enabling the unit to illuminate work indoors.
Four 1,000 W metal halide lamps, rotatable through 350 degrees, provide a lighting power of 360,000 lumens.
For environmental safety, the V9 is equipped with a fully-bunded base to ensure that all operating fluids (fuel, oil and water) stay within the machine. The integral 110 per cent containment tray has an easy drain facility, he adds.
The mast, which is raised hydraulically to the maximum height of 9 m in just 10 seconds, features automatic safety locking, offering resistance to wind speeds in excess of 100 kmph. For maximum safety, the mast is designed to be lowered slowly over 25 seconds and features a hand-brake mechanism to lower the mast automatically when the handbrake is off. Other safety features include an in-built level gauge, an emergency relief valve, and a grounding rod and cable for earth leakage protection.
With a length of 3.1 m (reduced to just 2.2 m with the optional foldable tow bar), a width of 1.3 m and a height of 2.2 m (mast retracted), the V9 offers compact proportions, allowing a plant hire company, for example, to transport up to nine of the light towers on a standard delivery vehicle, he says.
The V9 has an operating weight of 1,263 kg. Equipped with a 6 kVA Mecc Alte LT3/130 alternator and two 16A auxiliary sockets, the V9 is powered by the Kubota D1105 diesel engine, giving 8.4 kW of power at 1,500 rpm. The fuel tank capacity on the V9 is 130 litres, and the fuel consumption provides for a long run time of 73 hours without refuelling. A cold start package is available as an option.
For routine maintenance work, the rear door opens up completely providing a clear access to the entire power train, including the engine and alternator. The control panel includes standard instrument gauges, key start and an engine hour meter, with automatic protective shutdowns in the event of high water temperature, low fuel level and low engine oil pressure.
“The V9 LightSource is designed and built to withstand day-in, day-out operation and is protected for work for long periods without attention,” Schmalzried says. “Its rugged design has been fully tested by subjecting it to a prescribed endurance test track, using an accelerated lifetime approach to prove the reliability of the design and components. Other aspects of the tests involve making 6,000 stop/starts of the engine, an endurance test of 1,000 continuous running hours and exhaustive testing of the mast system.”
