The outside width of the system is approximately 6” [152 mm] to 9” [229 mm] wider than this measurement.
  • Page 23 Figure 16 Tension Strut Backup A. Locate the centerline of the system by measuring the proper offset from the hazard. See the drawing package supplied with the system. B. Mark the centerline of the system with a chalk line. C. Mark a construction line parallel to the center line and offset 6.5” [165 mm] to one side as shown in Figure 17.
  • Page 24 2) Anchor the Backup and Monorail See Figure 18 (showing Backup Assembly) and Figure 20 (showing Monorail deployment).

  • Page 29 7) Cylinder Attachment ® All QuadGuard Elite M10 Wide systems utilize three Cylinder types. Bay 1 contains a Cylinder with ME1 stenciled on the outer surface. The Nose Assembly contains a single walled 28” outside diameter Cylinder with QEN stenciled on the surface. All remaining Bays have Cylinders with ME2 or ME3 stenciled on the outer surface.
  • Page 30 9) Attach Remaining ME3 Cylinders Continue attaching the ME3 Cylinders to Diaphragms using 3/4X9” hex bolts, hex nuts and bar washers. Remove any clearance between the ME3 Cylinders and Diaphragms as you work forward from the Backup. Tighten all fasteners. Important: Diaphragm Extensions must be in place before Cylinder attachment.

  • Page 39: Maintenance And Repair

    Maintenance and Repair Important: Inspections are recommended, as needed, based upon volume of traffic and impact history. Visual Drive-By Inspections are recommended at least once a month. Walk-Up Inspections are recommended at least once a year. Visual Drive-By Inspection 1) Encountering a system with the Hit Indicator in the vertical position mandates inspection of the system.
  • Page 40 Note: The energy absorbing HDPE Cylinders lose their ability to absorb energy with increasing number of system impacts. After multiple full capacity design impacts, the system will no longer be able to meet the requirements as specified in MASH. To ensure that Cylinder replacement is accomplished before this condition occurs, it is essential that this part of the inspection be conducted every time the Hit Indicator indicates the system has been impacted.

  • Page 42: Post-Impact Instructions

    Post-Impact Instructions 1) Deploy the appropriate traffic-control devices to protect your crew. Warning: An impacted system can store energy in collapsed Cylinders and may spring back unexpectedly causing serious injury. Use caution during post-impact inspections for repair or refurbishment. Warning: It is the responsibility of the worker to keep hands and other body parts clear of system interaction.
  • Page 43 1.0” [25 mm] (p. 43). 13) Replace all damaged Cylinders. If a Cylinder’s condition is questionable, a photo of the Cylinder may be forwarded to Trinity Highway for evaluation (p. 3). 14) Tighten and torque all fasteners on the system (p. 36).
