There are many paradigms and legends surrounding maintenance
management in plants. Often, the legends are known to be untrue,
but people live with them because it is politically correct,
or simply convenient. To be successful in improving equipment
reliability and maintenance management, plants must break the
legends that exist in their organizations. Some of the legends
will be addressed in this article. You may find that these
legends are uncomfortably close to describing how your plant
operates.
Legend 4: Having more maintenance people on shift
reduces downtime
If you have many problems in your plant, operations typically
requests more people on shift to fix the breakdowns. If this
is the situation in your plant, you are going down the wrong
path.
If you have a multitude of problems in your plant, you need
to find out why and fix the source of the problems. What is
the solution for your plant? Most likely you don't have enough
time to repair all equipment problems found in your area, and
you don't always find the problems before a breakdown. So we
need more people, right? In the short run possibly, but not
necessarily. Definitely not in the long run. Here is a checklist
of possible problems:
- Do operators perform detailed equipment inspections? If
not, make sure operators know how to inspect a bearing, motor,
coupling, hydraulic motor, fluid coupling, etc.
- Do your maintenance people have detailed inspection lists,
take readings, and analyze trends in order to identify symptoms
on equipment?
- Do you use your craftspeople by having well-planned jobs
for them? Do you schedule maintenance jobs in coordination
with operations? By executing high-quality inspections, we
can make sure that we know about most symptoms.
