System Overview
The QuadGuard
®
HS, through crash testing, has been shown to be a potentially reusable, re-
directive, non-gating crash cushion, within NCHRP Report 350 criteria, for hazards ranging in
width from 24” to 90” [610 mm to 2285 mm]. It consists of energy-absorbing cartridges surrounded
by a framework of Quad-Beam
TM
Panels.
Important:
Valtir makes no recommendation whether use or reuse of any
part of the system is appropriate or acceptable following an impact. It is the
sole responsibility of the project engineer and/or the local highway authority
and its engineers to make that determination. It is critical that you inspect
this product after assembly is complete to make certain that the instructions
provided in this manual have been strictly followed.
The QuadGuard
®
HS system utilizes two types of cartridges in a “staged” configuration and empty
Bays to address both lighter cars and heavier, high center-of-gravity vehicles.
Impact Performance
The 9 Bay QuadGuard
®
HS systems have successfully passed the requirements stipulated in
NCHRP Report 350, Test Level 3 tests with both the light car and pickup at speeds of 70 mph
[113 km/h] at angles up to 20 degrees.
During head-on impacts, within NCHRP Report 350 criteria, the QuadGuard
®
HS has been shown
that it compresses rearward and crushes to absorb the energy of impact. When impacted from
the side, it safely redirects the vehicle back toward its original travel path and away from the
hazard.
Inspect Shipping
Before deploying the
QuadGuard
®
HS
, check the received parts against the shipping list supplied
with the system to ensure all parts are included.
Important:
The Manufacturer’s Drawing Package supplied with the
QuadGuard
®
HS
must be used with these instructions for proper assembly and should take
precedence over these general instructions.
Warning:
Do NOT modify the QuadGuard
®
HS in any way.
