- PARALLEL MODULE
- FATIGUE MONITOR
This task covers:
Bridge module open on a raised flat surface.
Fatigue monitors are only fitted to parallel modules.
Examine the fatigue monitor located centrally on the inner face of each parallel
If a crack has developed between the two holes in a monitor, this indicates that the
bridge module is within 1000 full load crossings of its design life.
If the monitor has cracked across its whole length, the bridge module has reached
the end of its useful design life; it must be taken out of service.
