release of avalanches in rocky, structured terrain from a central point.

Construction and function

• The cannon is permanently installed in centrally accessible and safe place
• The 1.8 m long arrow-type projectile is loaded with 2.2 kg of liquid explosive
• Nitrogen is used as a pressure medium
• The targets are test-fired at the time of commissioning.
• The alignment of the cannon and adjusting the necessary gas pressure ensure that the desired zones can be unerringly fired even without vision
• The arrow projectile is impelled into the starting zone and detonated on impact.

Main advantages

• Detonation over the snow thanks to the impact fuse
• range of approx. 1.5 km.
• The 2-component liquid explosive is safe when not mixed.
• In case of a failure the explosive is inactive again after 48 hours
• Release independent of weather
• Any number of targets are within reach for one cannon.
• No personnel in the avalanche danger zone.
