10m Folding Mast
The 10m mast is designed so that 1 worker can do the lowering and maintenance.
The ten-meter meteorological mast is made of iron profiles with a hot-dip galvanizing surface treatment. It is a folding mast with a folding pivot point at a height of 5,8m above the terrain. The detachable joints are made with stainless steel screws, in a few cases with screws with an anti-corrosion surface treatment.
The mast is anchored with steel cables with a diameter of 4,0 mm (for
applications at heights above 700m a.s.l. the diameter of the cables is 6,3 mm)
in two layers in three directions. For safety reasons, plastic tubes of
alternating yellow and black colors are strung on the cables up to a height of
2m above the terrain. Under the mast body is a base consisting of 2 concrete
tiles 45 x 45 x 10cm weighing approximately 45 - 50kg.
Three feet for anchoring the tensioning ropes are also composed of the same concrete tiles - each foot of 3 tiles with a total weight of approximately 150kg (for applications at altitudes above 700m. a.s.l., the foot is made up of five to seven tiles, depending on local conditions, weighing up to 350kg).
The tiles are tightened with a screw passing through
their center and ending with an eye for attaching the ropes. The tile assembly
is embedded in a dug pit 45 x 45cm with a depth of 30cm (for applications at
altitudes above 700m a.s.l. 50 - 70cm). This solution for anchoring the mast is
chosen with regard to possible temporary installations and allows for the least
possible interference with the terrain at the installation site.
The mast is easily dismantled and relocated to another
location.
The
feet for attaching the ropes are placed at a distance of 3m from the mast body.
All cabling from the sensors to the measuring station
is routed inside the mast body, which also provides mechanical protection and
shielding for the cables. The mast assembly also includes an arm for mounting
the wind speed and direction sensors and an arm for the sun detector sensor.
The mast is grounded with a grounding tape, which is usually placed at the
bottom of the trench for the power cable.
