The snow scale SSR-2 is a measuring device for automatic and continuous measuring of snow load on flat roofs and roofs with an inclination of max. 5°. It is used for security issues of buildings and helps the facility manager and owner to reliably decide if there is an over-load for the roof statics with the current snow load.
SECURITY ON THE ROOF
Extreme snow situations in winter and related roof collapses with personal injury show that the snow load measurement of flat roofs is a very important matter. Big amounts of snowfall followed by warm weather conditions with rain can be very critical for the statics of a roof. However, when exactly is the point reached, where the statics of the roof do collapse? How much snow is there on the roof already? Should there be done a clearing of the snow from the roof, which is very dangerous and cost intense, or is it still capable of carrying even more weight? Many very important questions, which can be easily solved by the installation of a SOMMER snow scale SSR-2.
