TSC-100-ZD

Area of Application

The TSC-100-ZD is a low energy rockfall catchment fence that has a hinged connection to the base plate and so requires upslope retaining ropes to support the post head. It has been tested according to the ETAG 27 guidelines and carries a CE marking. It fully meets the requirements for Consequence Class 3 of Appendix E of the ONR 24810 “Technical protection against rockfall – Terms and definitions, actions, design and construction, and monitoring and maintenance” and carries the highest performance rating available according to the Austrian Department of Avalanche and Torrent Control’s rockfall catchment fence type list. As such, it may be used on projects with all levels of risk.

Rope Guidances

The upper and lower bearing ropes are led through a rope guidance that is integrated on each post head and base plate. Each guidance provides large curved surfaces to help protect the ropes and allow unobstructed movement. The guidance is designed to be robust and with no movable parts in order to ensure longevity and zero maintenance.

Integrated Ladder

Each post has an integrated ladder composed of rungs spaced at 50 cm intervals in the webbing of the I-beam. The ladder assists in the installation of the fence as well as routine inspection and maintenance.

Base Plate

Hinged systems have independent base plates that are connected to the post using a pin. The lower bearing rope is led through a guidance attached to the base plate similar to that of the head of the post. The base of the post is secured to the foundation/subsurface through two rock or soil anchors, the front compression anchor oriented perpendicular to slope while the rear tension anchor is at 45 degrees to the base plate.

Lateral Anchorage

Lateral anchoring or internal anchoring of long sections of fences are achieved normally with one anchor having the main bearing ropes attached with brake elements, thimbles and shackles.

AVT-phx Brake Element

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.
