Universal TAU II

Purpose: The Universal TAU II crash cushion system is an end treatment for concrete barrier, beam guardrail, and fixed objects up to 8 feet wide.

Description: The system is made up of independent collapsible bays containing energy absorbing cartridges that are guided and supported during a head-on hit by high strength galvanized steel cables and thrie beam rail panels. Each bay is composed of overlapping thrie beam panels on the sides and structural support diaphragms on the ends. Structural support diaphragms are attached to two cables running longitudinally through the system and attached to foundations at each end of the system.

Functionality: Overlapping panels, structural support diaphragms, cable supports, cables, and foundation anchors allow the system to resist angled impacts and mitigate head-on impacts.

Foundation: The system is installed on a concrete foundation.

Slope: 10H:1V or flatter slope between the edge of the traveled way and the near face of the unit.

Manufacturer/Supplier: Barrier Systems Inc.
