Masts

We can refer to 25 years of experience in the field of wind measurements: Our tubular masts, designed in-house, are calculated for quasi-permanent installation and are certified in accordance with the EUROCODE 1 standard.

Our masts are galvanised for a long service life, and stainless steel is used for wire rope and tensioning screws. The use of high-quality materials keeps the follow-up costs for re-deployment low. Many of our masts have been erected and dismantled several times for over 15 years or have been in the same location for over 10 years without any significant maintenance costs.

Hrafnkel carries out the erection and dismantling of the masts. This also includes the design of the instrumentation for the measurment chain, site preparation, liaising with landowners and, at the customer's request, the authorization procedure for the mast installation. Our masts are erected in various types of terrain, on flat terrain as well as in extremely demanding terrain such as in the high mountains at 2400 metres. The ground mounting of the mast and instruments significantly reduces the risk of accidents on the construction site.

10-20 m - masts

In addition to the "large" masts, we also offer masts with heights of approx. 10-20 metres. Depending on the height and requirements, these are made of wood or tubular steel and are guyed on three or four sides.

30-50 m - masts

With a diameter of just 114 mm, our tubular masts are slim and therefore offer less surface for the wind to attack compared to a lattice mast. The smaller surface reduces the interference on the measuring instruments attached to the mast and thus reduces measurement uncertainty, especially for wind measurements.

The masts with heights of approx. 30, 42 and 50 metres are guyed on four sides. The guying radius is approximately half the height of the mast, which means that our masts can be erected in a small space. Steel tubes are laid at a depth of 1.6 metres in the four foundations as anchors for the guy wires. The loops running around them are cut and removed from the ground when the mast is dismantled. The steel tubes can also be removed from the ground upon request. If they remain in the ground, they are no obstacle to agriculture. Alternatively, wooden anchors can be used; these remain in the ground after dismantling and decompose over time.

70-110 m - masts

Masts with a height of over 50 metres are in preparation. In order to minimise transport costs and the need for tools, these masts are made of aluminium tubes.

Our masts have already been erected at sea level and in the high mountains at 2400 metres.
