Maintenance is one of the mainstays of running any business smoothly, regardless of size! Now with so many maintenance strategies going around, the question inevitably becomes is it worth investing the extra money and resources into preventive maintenance? Well, the short answer to that is yes, yes it is! And in today’s piece, we are going to explain exactly why you need to invest in it!
But before we go down that road, first let’s take a few words to briefly explain what the three terms mean – predictive, preventive and corrective maintenance.
In this maintenance strategy, the team responsible for the machinery keeps it in constant check and is ready to jump in and do the repairs at the first sign of trouble. This prevents the machinery from completely breaking down but still halts production lines for some time as the maintenance requirements can happen at any point during the runtime of the machinery.
This is when the machinery is regularly checked in on and repairs as well as maintenance work is done in fixed intervals so that the production line never comes to a halt. This system works best in conjunction with a CMMS. Another benefit of the preventive maintenance strategy is that you can somewhat accurately predict the lifespan of your machinery and thus order replacements in time.
Corrective Maintenance is generally avoided for expensive machinery but in some cases where the machine is expected to work till it fails, corrective maintenance can be a viable strategy. In essence, this is when the machinery stops working and the team responsible for it then tries to fix or replace the broken part. Now, there is planned corrective maintenance as well, and while some would argue that it doesn’t exactly fit the bill for preventive maintenance, in edge cases where the only viable option is to replace the machine or parts of it, it can be considered to be a part of the preventive maintenance strategy, provided that spare parts are readily available and always in hand!
Pros of Preventive Maintenance
When it comes to preventive maintenance, one of the major pros associated with it is that there is little to no downtime with this strategy. In the longer run, preventive maintenance manages to save more revenue especially when it comes to expensive and mission-critical machinery. It also helps in reducing the wastage of human resources as most of the maintenance is done when no actual work is being performed. Along with that, regular preventive maintenance also helps increase the life cycle of your resources and ensures that efficiency is never compromised upon. Along with that, preventive maintenance also removes the need for constant human monitoring which is a great bonus as most of the work is automated and performed by a CMMS.
So how does it differ from predictive maintenance? Well, the primary difference is that it doesn’t need a team of highly experienced workers to be constantly checking in on the health of the machinery. Along with that, it can sometimes become exceedingly difficult to predict when certain complicated machinery is about to break down which means that if an unexpected fault occurs, the entire production line comes to a screeching halt!
This is why as an overall safer and much more resource efficient maintenance strategy, preventive maintenance is preferred over the other two methods. Not only does it reduce the strain on the workforce, it also eliminates the human error portion of it as preventive maintenance is mostly scheduled by a CMMS that finds it pretty easy to monitor and schedule multiple pieces of machinery at the same time!
