Revolutionary New spiral HiMast takes Wind Monitoring to New Heights
Nexgen has developed a new design in wind monitoring masts that could revolutionise the wind monitoring industry. Our unique, lightweight 60m HiMast is made using spiral tubing than can withstand harsher environments than any of its competitors.
 The lightweight mast tubes are constructed in the same way as a cardboard tube, by winding steel in a spiralling technique. This method makes the structure much stronger and more stable in high wind; it also reduces the vibrations which can be a problem in traditional tall towers.
Lightweight for easy transportation
Dr Geoff Watson, Nexgen's Development Manager, explains the thinking behind his innovative new design, " We're constantly being asked by our customers for taller masts that can handle the harshest conditions at very remote sites. The key points were to make the towers much stronger, while keeping them lightweight for easy transportation. By using a steel spiral we've created a HiMast that is essentially a 'stiff spring' that absorbs any unwanted movement. It's been rigorously laser tested in simulated wind speeds of up to 200mph. We've also limited each tube section to 3m in length, making transportation and installation easier for any site."
The 60m HiMast consists of 20 tubes. From ground level to 36m, there are 12 spiral steel tubes with a diameter of 220mm. Above 36m the final eight tubes have a reduced diameter of 152mm. This not only reduces shipping costs but more importantly allows less wind resistance. According to Geoff, "The HiMast is quite simply the ultimate mast."
Coupler and guy plate combination
 Traditionally, wind mast tubes have either bolted or slotted together but there are disadvantages for both designs as masts get higher. Bolted masts are generally very heavy and need to be professionally installed, with the chance that bolts may come loose or be lost. Slot together masts tend to be fairly lightweight, however one of the major problems encountered by slot together masts is icing. When ice forms, the increased weight can force the tubes to slide down into each other in the heavily loaded lower section on very tall masts. This results in guys slackening, reducing both performance and stability.
"We've overcome this problem by designing something simple but effective. A coupler shaped like a cotton reel is slotted into the end of each HiMast tube. Its flattened end can also double up as a square guy plate with holes drilled in each corner to attach the guy wires. When icing occurs, the plate between each section prevents the tube from slipping," says Geoff.
Heavy duty 6mm guy wires are supplied with all HiMasts as standard, along with a reinforced, hinged base plate. The base plate can be used on any ground; if it's boggy, wooden planks can be easily inserted underneath if necessary.
15m Ginpole
Other standard features of all Nexgen WindMasts and HiMasts are hot-dip galvanised steel construction and a 10 year warranty against tube corrosion. Ginpoles are supplied for all tower heights and a new plug-together 15m ginpole is available for the new 60m HiMast.
By not incorporating the ginpole hinge into the mast baseplate, we're offering a much better engineered solution to the problems of erecting these very tall masts. It's all been developed in conjunction with the most experienced installation crews in the UK and they're very happy with it. On many sites a team of three can install a 60m HiMast in one day.

Measure the Wind Anywhere in the World with NOMAD 2
and the Iridium Satellite System
 We're now pleased to offer our customers two-way communication and data transfer from very remote sites with NOMAD 2 and the Iridium Satellite Network.
Many potential windfarm sites are in remote locations, beyond the reach of cellular service and regular site visits. But the Iridium satellite service uses a system of 66 low earth orbit satellites to provide complete coverage of the earth's surface. This means NOMAD 2 can be installed literally anywhere in the world, and still be able to transmit data from the site back to the office on a daily basis.
The satellite modem is a relatively low-powered device, and is available with a rechargeable 20 Watt solar charging system that will keep the meteorological station and modem running indefinitely. Real-time information from the data logger and sensors is only a phone call away and if there is a problem with the equipment, it will be known immediately.

Class 1 WindMast Replaces the Nested Mast
At Nexgen we're always keen to improve our products and supply customers with the best available options to suit their individual requirements. Because of this we've taken the decision cease manufacturing the nested wind mast. We will be stocking spare tubes and guys for the old nested masts until current stocks are depleted. The Class 1 WindMast in 30m, 40m and 50m heights is a more robust alternative. Find out more about our range of Class 1 WindMasts

Nexgen Supports Hadrian's Wall
 A new Hollywood film about the legendary British King Arthur is now showing in UK cinemas with Nexgenfeaturing in a supporting role!
A replica of England's historic Hadrian's Wall was built for the film using 500 of our Screw-in Anchors to support it. The wall took 300 people 14 days to build and was part of the biggest set ever created in Ireland.
After filming was completed the whole set, including the 6 inch Screw-in Anchors (which have a 3 Ton capacity) were removed, restoring the Irish countryside to its former glory.
