Wyssen - Model LS6-5 -Mini Avalanche Tower
Operation is being done via the Wyssen Avalanche Control Center WAC.3®; The tower is placed in the avalanche starting zone; Up to 6 charges can be loaded at 4-5kg (9-11 lbs) of explosive each; Reloading is being carried out manually over the ladder on the mast; Power supply is provided by batteries supplied by solar panels; For the deployment a charge is being dropped out of the deployment box; During the free fall of the charge a double ignition is activated; The charge detonates hanging on a cord above the snow cover after a time delay; The charge height is adjustable when the charges are prepared and loaded.
The deployment box is fixed on the tower. Solar panels are installed at the deployment box as well as the antenna. Inside the box sealed from the elements is the deployment mechanism, electronic control and the prepared explosive charges. Thanks to the smart concept highest reliability is guaranteed.
The explosive charge consists of two orange half-shells with pre-mounted pull activated percussion igniters with slow fuse, which are assembled with 4-5 kg (9-11 lbs) of explosives. The charges are assembled by the operator on-site. Explosives and other pyrotechnical elements are purchased directly by customers from the appropriate suppliers. The plastic is made of biodegradable material.
- Air blast with a big charge (effective range of up to 260 m (850 ft) in diameter)
- Simple and low priced alternative to the Wyssen Avalanche Tower LS12-5 and LS24-5
- Operation via WAC.3® just as the Wyssen Avalanche Tower LS12-5, LS24-5 and other systems
- Remote control permits rapid and weather-independent release
- No personnel in danger area
From the avalanche operator’s point of view, a blasting installation must be extremely reliable and effective as well as simple to operate and maintain. The installation in the terrain must be straightforward and the interference of the installation must have minimal impact on sensitive mountain environments. The Wyssen Mini Avalanche Tower is ideal for fulfilling these requirements.
- Blasting above the snow with bigger charges (4-5kg /9-11lbs) gives the maximum effective range up to 260m in diameter (850 ft)
- Explosives with high detonation speeds produce N-shaped pressure waves which have been proven to cause the best release effect, particularly at a greater distance from the detonation point
- Positioning a tower on a prominent terrain feature and including a 12m (39 ft) tower instead of 10m (33 ft) enables the effect to be reached in locations of pressure shadow (in couloirs, behind terrain ribs)
- Releasing smaller quantities of snow in increments, decreasing possibility for larger avalanches
- Very good stability test for assessment of the local avalanche danger
- Low investment and operating cost in comparison with permanent protective measures (snow sheds, bridges, tunnels)
- Lowest operational costs thanks to its ingenious system concept
- Damage to infrastructure is avoided by the release of smaller portions
- Economic benefits thanks to reduced closure times
- No critical or moving parts are exposed to the weather
- Solar power supply or wind generator avoids the necessity of vulnerable supply lines in the terrain
- Annual maintenance ensures maximum reliability
- Preparation of the charges takes place in protected areas
- Remote-controlled installations allow operation around the clock
- Very rapid operation possible
- Short closure times
- Less time snow plowing as avalanches are released in smaller portions
- Foundation Footprint is only 1m2
- Short construction times in the terrain simplify planning and implementation
- Blasting over the ground prevents damage to the vegetation cover
- Dismantling after operating life possible without any problems
- Intuitive web-based operating interface
- Operable from any web-enabled device (Computer, Tablet, Notebook, Smartphone)
- Operation independent of location
- Multiple release from Avalanche Towers possible
- Monitoring of systems 24/7
- Automatic documentation and archiving of activites and system data
- Data transfer via mobile network, radio connection or satellite
- ExploDoc
- RiskEval
- ComTool
- HeliTrack
- Weather stations
- 3D snow height measurement via LIA® etc.
