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. Be aware of tools (pry bar, etc.) that could move
unexpectedly if a bind is suddenly released.
2) P osition a minimum 1 ton p i c k u p truck on the system just in front of the Nose Assembly.
Place the truck bumper against the system. The truck bumper height, approximately 24”
[610 mm], should rest against the middle center of the Nose Assembly.
Warning:
Once the bumper is over the system’s Monorail, the vehicle may be
subject to pushing force due to unexpected restoration. The driver should be
wearing a seat belt and have the vehicle in the lowest possible gear when
approaching the system. In the event that the system unexpectedly deploys
before Step 2 is complete, the driver should apply the brakes immediately to bring
the vehicle to a controlled stop. The vehicle must be in neutral while still applying
the brakes and then gradually release the brakes to allow the system to restore
against the truck bumper in a safe and controlled way.
3) Once in place, carefully move the truck so the bumper displaces the Nose Cylinder 6”. In
the absence of the Nose assembly, place protective material between the bumper and the
first Diaphragm leaving a 1.00” gap between the protective material and the truck bumper.
It is the responsibility of the driver to remain in the vehicle to apply the brake during initial
system displacement.
Caution:
Use a pry bar with a 1 ton truck to release additional mechanical binds
in a safe and controlled manner.
4) Wrap a chain, 3/8”X20’ Grade 40 minimum, around the first Diaphragm (Figure 44). Attach
both ends of chain to truck bumper anchor points.
Important:
Wrap chain around the first
Diaphragm so the pull force is aligned with the
long slots in the Fender Panels to ensure a
smoother extension.
Warning:
Stand clear in case chain breaks or
becomes disconnected.
Important:
Have someone watch during
repositioning to ensure undetected damage does
not cause the Diaphragms to bind or pull out
improperly. Wait ten minutes after full extension
for Cylinders to regain their former shape.
