KONA Climbing Derrick system in action

KONA Climbing Derrick system for reducing wind measurement instrument uncertainties on tubular met masts.

Over the past number of years KONA has used our Climbing Derrick system for installing wind measurement instruments to a higher degree of accuracy on tubular met masts. By using laser measuring technology with inclinometers we can adjust each instrument individually, compensating for any mast distortion in the X & Y plane.

KONA can also efficiently replace or upgrade instruments individually using the Climbing Derrick, removing the need to tilt down the mast.

Another milestone for KONA

KONA has secured the contract to install two 100m SLX5 Permanent Met Mast for our client Gaeltec – KTL who are constructing the Mount Lucas and Bruckana windfarms for Bord na Mona. The SLX5 is our self supporting model which is designed to BS8100 & BS5950 for 25 years on site service life.

This contract represents another milestone – the SLX5, the tallest self supporting masts in our company’s history.
