5) Ensure the Mushroom Washer Assemblies holding the Fender Panels together are still
intact and the system has not been deformed to prevent it from pulling back fully to its
original position.
Caution:
Use eye protection and gloves when repairing any Mushroom Washer
Die Spring Assembly. Do not place fingers underneath an assembled Mushroom
Washer. Parts may suddenly shift and fingers may be pinched. If the Die Spring is
still under compression, then secure it with a clamp to ensure safe action and
release when the nut is removed.
6) The system should now be safe to approach for debris removal and further mechanical
binding inspection. Binding is typically located at the Monorail Guides near the front
Diaphragms or Fender Panels.
7) Verify all Anchor Bolts are firmly anchored to the roadway surface. Replace any loose,
broken, or pulled out Anchors. Proper performance of the system depends on the Monorail
Anchors being properly deployed.
8) All Diaphragm Support Legs must be properly attached to the Monorail.
9) Inspect the system in accordance with the QuadGuard
®
Elite M10 Wide Maintenance Flow
chart (p. 40). The Cylinders are potentially reusable after typical design speed impacts.
See the Limitations and Warnings section on page 5.
10) Diaphragms that are bowed or have bent legs must be replaced.
11) Each Fender Panel must be properly attached with a Mushroom Washer Assembly. Check
all Fender Panel to Diaphragm bolt connections. All damaged bolts, Fender Panels and
Transition Panels must be replaced.
12) The maximum gap allowed for overlapping Fender Panels on the side of the system with
traffic approaching from the rear (including Fender Panels overlapping components
behind the system) is 1.0” [25 mm]. Mushroom Washer Assembly
nuts must be tightened
to the bolt shank. Replace damaged parts if a gap between any Fender Panel exceeds
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).
15) Clear site debris.
16) The QuadGuard
®
Elite M10 Wide is ready for use.
Important:
Because every impact is different, Trinity Highway makes no
recommendation whether use or reuse of any part of the system is
appropriate or acceptable following an impact. It is the sole responsibility
of the project engineer and/or the local highway authority and its engineers
to make that determination. It is critical that you inspect this product after
assembly is complete to make certain that the instructions provided in this
manual have been strictly followed.
