the actual scraper because, up to that point, it wasn't
broken, so why fix it? In these cases, it took the cost of
replacing the blades and the belting for maintenance
to realize these items needed to be checked regularly.
After hours of maintenance to remove the buildup
and properly adjust the scrapers, personnel developed
a schedule that included clearing the scrapers. Time
allotted was approximately two minutes per scraper
per month. When looking at the initial numbers, the
facility was nervous about the added time. " We don't
have time to cover this. " However, when factoring the
breakdown time to get the systems back to working
order, more labor hours were spent bouncing between
priority projects and fixing broken components than
when a solid PM plan was implemented. Additional
savings were realized because the belt and other components would not have needed to be replaced.
Another consideration is to use technology. There
are wired and wireless units that monitor noise and

vibration, along with oil and grease levels. These
units can be monitored from one location with
actuating preemptive signals to alert personnel that
service should be performed. This technology can
detect issues, stresses, and potential breakdowns even
before there are visible signs.
Today's technology provides several devices and
systems that can help maintenance focus on what is
important. Some of these devices and changes involve
a significant up-front cost, but the true ROI-the true
savings from preventing failure-more than justifies
the investment. EP

An effective predictivemaintenance plan
for conveyor systems
will account for all
components, not just
those that are easily
evaluated.
