TS-LV Snow Catcher

Area of Application

The Snow Catcher is a dynamic defense structure installed in the avalanche deposition zone that helps dissipate energy and reduces the total runout length of an avalanche. They can be used where the cost of static defense structures is high or where a linear mitigation measure is preferable.

Self Supported

The post is similar to the lambda frame used for debris flow structures. It is self supporting, having a primary post in the plane of the net and a brace on the downslope side.

Brace-Post Connection

The connection between the primary post and the brace is through tongues with a large diameter pin for ease of installation. The post is subsequently reinforced in this area to resist buckling.

Base Plate

The base plates are designed to be secured to a foundation or bedrock with four bolts. The bolts are normally short pieces that are tied into the reinforcement elements of the foundation.

Rope Guidances

The bearing and middle ropes are led through rope guidances integrated in each post, providing large curved surfaces to help protect the ropes and nets and which allow unobstructed movement. The guidance is designed to be robust and with no movable parts in order to ensure longevity and zero maintenance.

Lateral Anchorage (Horizontal)

The system can be anchored at the open ends of the fence or internally using standard anchors or reinforced anchorage. This allows a system to be built in long sections. Long barriers consist of multiple sections of fencing that act independently.

AVT-phx Brake Elements

The AVT-phx series of brake elements are steel coils that unravel when a force is applied. The gauge, width and number of coils can be specified in order to control the amount of energy absorbed and the total displacement. With no moving parts, these are some of the safest and most reliable brakes in the industry.
