ABSTRACT:
The invention relate to a lighthouse or beacon construction characterized in that in order to isolate vibrations, the upper part of the construction is not in rigid connection with the lower part subject to forces which cause vibrations, but the construction is broken at a suitable height and the upper part is mounted on the lower part so that it is supported by slide rails, roll rails, wheels, a flexible or pivoted parallelogram mechanism or elastic poles, or a corresponding flexible mechanism, so that the lower part can move substantially horizontally in relation to the upper part while the upper part is maintained in substantially vertical position.
