Attenuator Economical Alternative For Low Impact Areas
QUEST impact attenuator is being introduced by Quixote Transportation
Safety, Inc. as an ideal, economic crash cushion solution for low
impact areas, that features fast and simple installation in that
it is available already assembled.
The QUEST System consists of a series of w-beam fender panels supported
by diaphragms with a trigger mechanism at the nose which, when hit,
releases a “front assembly” to absorb the energy of
impact. The system has a small “footprint,” measuring
only 5.74 m (18’10”) long and 610 mm (24”) wide.
During head-on impacts, the QUEST System telescopes rearward to
absorb the energy of impact and bring the errant vehicle to a controlled
stop. When impacted from the side, the QUEST is capable of redirecting
vehicles at angles up to 20°. Refurbishment typically involves
replacing a damaged unit, with repairs done off-site.
The QUEST System meets NCHRP 350, TL-3 criteria and performs effectively
at design speeds up to 100 km/h (62 mph).
The QUEST System is designed for fast and easy installation. Assembled
at the factory, the QUEST is ready to be installed. Thirty anchors
are all that are required to install. If required, the unit can
be shipped unassembled.
Recommended applications for the QUEST are:
• Large Gore, Wide Median and Shoulder
• Low impact areas – less than one (1) full scale incident
• Low nuisance hit site
• Sites with unlimited accessibility
• As an alternative to sand barrel arrays
• With double faced guardrails
