In the summer of 2018, the Jennylund athletics arena in Bohus was inaugurated. The facility has been gradually developed and in order to be used for most of the year, electric lighting was needed. We were entrusted to develop a solution and four 18m high LIGHT MASTequipped with PRECISION 3 were built ready on the ground to be lifted into place by helicopter. This was a way of avoiding any ground damage that a mobile crane might cause. Brave fitters solved the task and now Jennylund's athletics stadium shines at its best.
