REACT 350® II - Energy Absorption Systems

Backup TypeIt is important to fully understand the limitations of each backup type so the correct REACT 350 ®II system is chosen for each location.The REACT 350 ® II system is available with a Self-Contained Backup or may be attached to aConcrete Backup. Refer to Figures 4a and 4b, along with the backup assembly drawings, todetermine which type of backup is appropriate.Self-Contained BackupREACT 350 ® II System with a Self-Contained “steel tube” Backup require two cables, one cableon each side of the Cylinders. These cables begin at the front of the system, travel through theCable Guides on the Cylinders, loop around the backup structure, travel back through the CableGuides, and terminate at the front of the system.Concrete BackupREACT 350 ® II System with a Concrete Backup requires four cables. Two cables on each sideof the Cylinders begin at the Side Anchor Plates, travel through the Cable Guides on theCylinders, loop around the pin on the Front Anchor Plates, travel back through the CableGuides, and terminate at the Side Anchor Plates.Existing concrete structures may serve as backups for REACT 350 ® II system provided theymeet specific size and strength requirements.ConcreteBackupOne Cable, Two RunsSelf-ContainedBackupTwo Cables, Four RunsFigure 4aFigure 4bwww.energyabsorption.com Revision A July 2013www.highwayguardrail.com 12 All rights in copyright reserved
