Post-Impact Instructions
Important:
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 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.
1) Deploy appropriate traffic-control devices.
2) Ensure all anchor bolts have remained firmly anchored in the roadway surface. Replace
any loose, broken, or pulled out anchors.
The performance of the system during an angle impact depends on a properly
anchored Monorail.
3) Clear and dispose of any debris on site.
4) Ensure the Mushroom Washer Assemblies are intact so the system can be restored to its
original position.
Caution:
Use eye protection and gloves when refurbishing the 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 as the nut is nearing the end of the bolt, to
prevent injury make sure that the Die Spring is restrained with a clamp so it does
not suddenly release when the nut is removed from the Mushroom Washer Bolt.
5) The Diaphragm Support Legs are all properly attached to the Monorail.
6) Remove the Nose Assembly and attach a chain to the Pullout Brackets on the first
Diaphragm (Figure 36). Attach both ends of chain to a heavy vehicle (such as a 1 ton
pickup).
Warning:
Stand clear in case chain breaks or becomes disconnected.

Pullout Brackets
Important:
Slowly pull the system forward to its original length. Have someone
watch the repositioning to ensure undetected damage does not cause the
Diaphragms to bind or pull out improperly.
