Preventive maintenance: the tactic for a long and cost-efficient machine life

Better safe than sorry, as the old saying goes. When it comes to maintenance, it proves to be true: a well thought-out maintenance strategy that prevents malfunctions or even complete failure of your systems increases the service life of operational assets and saves costs in the long term.

There are many possible measures, and preventive maintenance is a method of maintenance management that has become uncomplicated, especially in the digital age. Provided you work with the right tools to protect your business from malfunctions and breakdowns.

How this works, what exactly preventive maintenance means and how we can support you: You can find out here.

Preventive maintenance: Definition

Preventive maintenance is a strategic measure in which companies regularly maintain their machines and systems in order to avoid unplanned downtime. This form of maintenance is based on systematic planning and includes targeted maintenance measures that continuously monitor and optimize the condition of the systems.

So you don’t wait until a problem stops production or leads to downtime, but try to prevent problems that could arise due to wear and tear in advance by taking preventive measures.

The aim of preventive maintenance is to identify and rectify problems at an early stage, for example before defective devices affect uptime and productivity.

Companies use various strategies to minimize the amount of work required for maintenance and repairs. This includes regular inspections and a structured maintenance plan.

Whether and which measures are worthwhile compared to repairs in an emergency can vary greatly from company to company. This is why maintenance processes in different areas are an individual matter.

Maintenance and servicing work in times of digitalization

Digitalization makes preventive maintenance measures even more efficient. No matter in which company we look at maintenance: The days of routing slips, manually completed checklists and inspection reports are definitely over.

Digital tools analyze large amounts of operating data and enable predictive planning of maintenance work. This enables companies to optimize their maintenance strategies and extend the service life of their machines. Compared to “analogue maintenance”, the digitalized version is far superior in terms of workload.

The implementation of preventive measures requires close coordination between the various areas of production and maintenance. Well thought-out planning not only reduces downtimes, but also contributes to cost efficiency.

Ultimately, preventive maintenance increases the reliability and performance of machines and systems. Companies that rely on these strategies secure competitive advantages and guarantee long-term plant availability, despite the manageable costs for monitoring and the resulting processes.

Types of maintenance

Maintenance strategies can vary greatly depending on the industry and company. However, they should all be efficient and cost-optimized.

Let’s take a look at the different types of maintenance that are conceivable for increasing the availability of your assets.

The following options are known to be common in maintenance:

Reactive maintenance, or “run to failure”, sets the repair team in motion as soon as devices or machines come to a standstill. In other words, the team only reacts when the wear and tear or breakdown makes a response absolutely necessary. Corrective maintenance is also sometimes referred to. Depending on the production system, this can sometimes save costs, but it can also be really expensive.

Predictive maintenance, also known as preventive maintenance or PM for short, is more active: instead of waiting until problems occur, regular inspections are carried out, for example according to a specified maintenance plan, to ensure that expected failures are avoided from the outset.

Predictive maintenance means using collected data and information to predict when and where a failure will occur. Precise measures can be taken in advance at this point to prevent the predicted system failure.

The two maintenance strategies – predictive and preventive maintenance – have similarities, but offer different advantages. Both describe a proactive approach: Companies try to fix problems before they even arise. This usually involves lower costs and less manpower than trying to rectify a production stoppage as quickly as possible once it has occurred.
