Customer Service Contacts Energy Absorption Systems (a Trinity Highway Products company) is committed to the highest ® level of customer service. Feedback regarding the QuadGuard II system, its assembly procedures, supporting documentation, and performance is always welcome. Additional information can be obtained from the contact information below:...
Important: Read safety instructions thoroughly and follow the assembly directions and suggested safe practices before assembling, maintaining, or ® repairing QuadGuard II system. Failure to follow this warning can result in serious injury or death to workers and/or bystanders. It further compromises the acceptance of this system by the FHWA.
II for assembling, maintaining or repairing QuadGuard system. Do not utilize or otherwise comingle parts from other systems, even if those systems are other Energy Absorption Systems or Trinity Highway Products systems. Such configurations have not been tested nor have they been accepted for use.
Limitations and Warnings Energy Absorption Systems, in compliance with the National Cooperative Research Highway Program 350 (NCHRP Report 350) “Recommended Procedures for the Safety Performance of Highway Safety Features”, contracts with FHWA approved testing facilities to perform crash tests, evaluation of tests, and submittal of results to the Federal Highway Administration for review.
System Overview ® QuadGuard II is a potentially reusable, redirective, non-gating crash cushion for hazards ranging in width from 610 mm to 2285 mm (24" to 120"). It consists of energy-absorbing Cartridges surrounded by a framework of Quad-Beam panels. ® QuadGuard II system utilizes two types of Cartridges in a “staged”...

How to Determine Left/Right To determine left from right when ordering parts, stand in front of the system facing the hazard. Your left is the system’s left and your right is the system’s right. Counting the Number of Bays One Bay consists of one Cartridge, one Diaphragm, two Fender Panels, etc. The Nose section is not considered a Bay, though there is a Cartridge in the Nose of each system.

Measuring the Width ® The QuadGuard II system is available in seven nominal widths: 610 mm [24”] 760 mm [30”] 915 mm [36”] 1219 mm [48”] 1755 mm [69”] (Minimum 3 Bays Required) 2285 mm [90”] ...
® QuadGuard Deployment Criteria Contact Energy Absorption Systems Customer Service Department if you would like input as to your specific application. Proper model selection is essential to the performance of the ® QuadGuard II system. You will need to answer the following questions: 1) Specification of System Width ®...

B. Is there a cross-slope at the construction site? Cross-slope exists – If there is a cross-slope of more than 8% (5 degrees), or if the cross-slope varies (twists) more than 2% (1 degree) over the length of the system, a concrete leveling pad may be required (See Figure 4).
Page 13
6) Other Factors that May Affect Your Deployment: 1. The existence of drain inlets. 2. Junction boxes or other appurtenances located near the hazard. 3. Insufficient space for the length preferred. 4. The location and movement of expansion joints. If these or any other special site conditions exist, please contact Energy Absorption Systems Customer Service Department before proceeding with your design (See Page 3).

Transitioning ™ Quad-Beam End Shoe Transition Panel ™ ® The Quad-Beam End Shoe Panel transitions the QuadGuard II system to vertical faced concrete structures whether it is a concrete Backup or concrete barrier wall (See Page 20). An Extended End Shoe is also available. In cases where the corners of the hazard are not chamfered, it may be necessary to add wheel deflectors to the structure in order to prevent wheel interaction.
Transition Panel Types If a system is placed in a location where traffic will be approaching from the rear, a Transition Panel is necessary. Figure 8, 9, 10 and 11 show standard panel types. There are variations for each panel type. The specific panel applied will depend on system and site conditions. Therefore, it is important to send site specific data to the customer service department for a recommendation for exact panel requirements of your application.
® QuadGuard II cz Deployment Criteria ® This portable compact crash cushion is for construction zones. The QuadGuard II cz is available in the same narrow sizes as permanent systems. ® The QuadGuard II cz must be properly anchored (See Pages 15 and 16 for the recommended anchorage of various foundations).
® QuadGuard II Foundation/Anchoring Concrete Installations ® For concrete installations, the QuadGuard II system should be installed only on an existing or freshly placed and cured concrete base (28 MPa [4000 psi] minimum). Orientation of the concrete base and the attenuator must comply with the project plans or as otherwise determined by the resident project engineer or appropriate highway authority.

Assembly ® The QuadGuard II system is potentially reusable. The system must be inspected after each impact and must be pulled out to its original length. Depending on the impact, components may get damaged and need replacement. That decision is for the appropriate highway authority specifying the maintenance to be performed.
