TSC-1000-ZD Hybrid

Area of Application

The TSC-1000-ZD Hybrid is a medium energy rockfall attenuator/hybrid rockfall fence that has a hinged connection to the base plate and so requires upslope retaining ropes to support the post head. A major difference to traditional fences is that the lower bearing rope has been removed from the base plate to a point lower down the slope (or optionaly completely left out). This allows debris that is stopped by the fence to progress further downslope to a point more suited for removal. It has been tested following the ETAG 27 guidelines.

Rope Guidances

The upper bearing rope is led through a rope guidance that is integrated on each post head. The guidance is designed to be robust and with no movable parts in order to ensure longevity and zero maintenance.

Base Plate

As with all hybrid rockfall systems, the lower bearing rope has been removed off the base plate to a position further downslope. This allows the debris to move through the system to a lower point. The base plate uses the standard anchor configuration of one tension anchor and one compression anchor.

Lower Bearing Rope Plate

The use of the lower bearing rope is optional. In the case of a hybrid system, it is recommend to use a lower bearing rope that is anchored at a plate with a spacing at least equivalent to the post spacing. This will help contain debris at the bottom of the system. In contrast, if the system is being used as an attenuator, the bearing rope can be completely neglected.

AVT-phx Brake Elements with Locks

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. In some cases, it may be desired to limit the activation of brake elements in order to reduce maintenance of following minor events. Both the 1000 and 3000 kJ hybrid systems have been tested with brake locks that prevent the expansion of the brake elements until a per-determined load is applied.
