Quest® Impact Attenuator Economical Alternative For Low Impact Areas

The 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 per year
• Low nuisance hit site
• Sites with unlimited accessibility
• As an alternative to sand barrel arrays
• With double faced guardrails
