Lighting tower releases continue to respond to demand for low emission products, with compact, versatile options of key interest to rental. IRN reports.
Extended run times for light towers
Doosan Portable Power has launched the LVL 50 Hz portable light tower for the Middle East and Africa markets. Designed for reliability and durability, the tower - also available as a 60 Hz model - is described as “ideal for the rental market.” It has a compact footprint job site mobility and easy transport.
“Applications include lighting for special events, road and bridge construction sites and all general construction applications, as well as providing lighting for emergency and disaster relief, oil and gas drilling and for mining and quarrying locations,” Doosan Portable Power confirms.
The LVL light tower has a power train based around the Yanmar L48N5 Tier 2 diesel engine, with a high output alternator, offering extended run-time of 220 hours (200 hours for the 60 Hz version).
“The four efficient and 300 W LED lights give a total output of 1200 W, providing the same area of lighting coverage as the previous generation metal-halide lighting tower. The durability of the LED lights is also a significant improvement providing up to 50 thousand hours of lifetime. This means that the LVL can be kept running for much longer and at a lower overall cost.”
“Whether it is the forklift capability, single-point lifting, or towing eye, the user has the benefit of many options for moving the unit. Repositioning the light is very simple, thanks to the 7-metre (23 ft) telescopic extension and full 360-degree rotation.
The new vertical mast also allows more units to fit into a standard 40-feet shipping container. Set up simply requires the draw bar to be dropped down, the fuel tank to be filled and the unit to be started.
Also “rental ready” are Generac Mobile’s CUBE PRO and V20 PRO which launched just over a year ago. Described as “plug-in hybrid” lighting towers, they allow the user to select the type of power supply of the machine, offering a “3 in 1” model that is either: 100% electric (powered only by the built-in battery pack); Stage V Diesel engine (powered only by the built-in generator); or a hybrid system (powered by automatically alternated generator/battery cycles).
The PRO lighting towers have two power sockets (Multipin and CEE), further extending the multiple use concept to connect to a Generac new Solar Kit (via Multipin socket). This option allows to use the unit in Hybrid Solar mode or a new Battery Pack (via CEE socket) which allows the unit to be used in extended electric mode.
The Solar Kit has 3 x 330 W photovoltaic panels, which can recharge the batteries integrated in the PRO lighting tower during the day. The panels can be tilted and stacked using sliding guides for transport and storage.
Generac says the PRO models allow rental companies to choose a single lighting tower model for their fleet, meeting requirements of the new World Green Deal and meeting a range of customer needs “without having to diversify their fleet and increasing the speed of return on investment and ease of fleet management.”
Lighting towers with low emissions
The Trime Group is continuing to make what it describes as “substantial investments” in the development of low and emission-free lighting towers under the Trime T-Zero brand.
Three lighting towers in the range attracting demand are the X- Eco Hybrid Lithium, and the award winning X- Solar Hybrid, alongside the X-Solar - an emission and noise-free solar only lighting tower.
Powered by lithium battery technology, the X- Eco Hybrid Lithium can be fully recharged in less than two hours; in a ten-hour cycle, for 80% of operation, the light is powered solely by its batteries and emits zero noise and zero carbon emissions.
Trime says solar power is becoming the preferred option by site managers, driving demand from rental firms for fossil-fuel free machinery, and therefore for the two solar powered lighting towers, the X-Solar Hybrid and X-Solar.
The former is powered by a combination of solar and engine power and will run for 3,000 hours before refuelling is needed, at which point it uses 0.55 litres of fuel per hour. The X-Solar sets are powered by solar panels that the company says make them emission and noise free.
The new products feature a nine-metre vertical mast and LED lamps designed to target worldwide rental markets.
Meanwhile, targeted at the European market, the HBOX+ from Himoinsa features long running time and 600-hour service intervals. It has “innovative connectivity features” and a two-cylinder stage V Yanmar engine designed to ensure “competitive fuel consumption levels.”
“With a light capacity of 210,000 lumens, the HBOX+ incorporates 4 x 350 W LED spotlights (50X50 SMD Chip Technology). Its hydraulic mast reaches a height of 8.3 m and can rotate through 360°, thus guaranteeing optimum light coverage.”
The tower also features a SafetyMast, an electronic control device that can detect obstacles, impacts and high wind speeds and can regulate the height of the mast autonomously depending on the strength of the wind.
The HBOX+ also has LED Dimming Control, while the CET8 controller includes automatic working mode (start/stop), engine Run/Stop, mast Up/Down and lamps On/Off, as well as a reverse mode when the stop is activated.
Other features include wide doors on all sides and on the roof, with a removable frame for cleaning and maintenance, while the interior contains emergency LED lights in case the equipment is switched off.
The tower is also able to withstand wind speeds of 110 Km/h or more and to facilitate transport, it features a lifting hook at the top and mounting points on all four sides of the frame for forklifts. Up to 22 units can be transported in a 13 m mega-trailer truck and 20 units in a 40’ container.
Battery innovation in light towers
Bruno’s offering includes LED lighting towers, energy storage systems and hybrid generators. The company says an important feature of its offer are Italian made lithium batteries (LiNMC type) manufactured by the Bruno Group’s battery specialist Archimede Energia.
Bruno says of the batteries that they “stand out for high energy efficiency and longer life cycle with a constant performance over the time, faster and less frequent recharge for a higher productivity compared to traditional batteries. They do not require maintenance and have a small carbon footprint.”
