What is the most common type of maintenance?

Preventive maintenance: This is usually carried out in the form of regular inspections, which are usually carried out several times a year. Another is that new technologies enable new strategies. When new technology gives us new capacity, we can take advantage of it in a new strategy. For condition-based maintenance and predictive maintenance, for example, the sensors installed on your assets and equipment capture a constant stream of data that you can use to help determine when to schedule upcoming inspections and maintenance tasks.

Here, you use a program of inspections and tasks to find and fix small problems before they have a chance to turn into big problems. Preventive maintenance is basically the idea behind the old saying that “an ounce of prevention is worth more than a pound of cure”. One way to understand the benefits of preventive maintenance is to analyze all the problems that are avoided. Default maintenance consists of simply following the manufacturer's recommendations for maintenance, including when to perform inspections and maintenance.

Basically, it's the same as condition-based maintenance, except that the data is analyzed to make accurate predictions about future faults. It now has the same maintenance costs depending on the conditions, plus the additional cost of even more sophisticated software that requires even more specialized training for its staff. For assets that don't fit any of these descriptions, it probably makes more sense to use preventive maintenance. As with many other strategies, you don't have to make a difficult choice between strictly one or the other.

When an asset is newer, you can use default maintenance. Later, when you've created a maintenance and repair history, you can start adjusting the schedule to better suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits and drawbacks. The tendency to fail usually has a bad reputation, but for a specific asset class and equipment, it is the best option.

Use it when things are difficult or impossible to maintain, cheap to carry in inventory, easy to replace, or not essential to your operations. Preventive maintenance helps you detect problems early by scheduling inspections and tasks. It also saves you money and frustration, since you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that you follow a schedule set by the manufacturer, not by your department.

State-based and predictive using sensors and special software to collect and analyze data from sensors installed directly on or near your assets. Depending on the conditions, the software searches for readings outside the preset parameters. For prediction, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no perfect strategy for all time.

You must choose the combination that best suits your assets, adjusting your approach as your assets age and your department collects data. Predictive maintenance (PdM) aims to predict faults before they occur so that maintenance can be done at the right time. PdM uses machine sensor data and intelligent technology to alert maintenance staff when equipment is at risk of failure. For example, a sensor can use vibration analysis to alert maintenance staff that equipment is at risk of failure, at which point it will be disconnected, inspected, and repaired accordingly.

To start performing preventive maintenance (PM) tasks, an organization doesn't need to buy new technology if it already has a CMMS. This is not the case with predictive maintenance, which requires health monitoring sensors and new software integrations.

However, with preventive maintenance, the organization risks overscheduling maintenance tasks because tasks are scheduled based on time and not on actual conditions. That said, preventive maintenance achieves a cost savings of 12 to 18% compared to reactive maintenance. As with all types of maintenance, relying solely on preventive maintenance has potential drawbacks. Depending on the budget, the amount of resources, the combined level of experience and the organization's maintenance objectives, one or more types of maintenance are used.

For detailed information on types of preventive maintenance, how to design a preventive maintenance program, preventive maintenance tools, and more, see the link at the beginning of this section. This type of maintenance is described as planned because it is based on well-established maintenance programs and concrete data. When it comes to types, techniques and costs of maintenance, the main types of maintenance can be compared with those of the human body to get an overview of the equivalent body maintenance task. Even a state-of-the-art manufacturing plant that has predictive maintenance technology will use less advanced types of maintenance.

Planned maintenance means that a maintenance planner or other type of maintenance worker has fully planned the availability of parts, materials, skills, and other resources during the scheduled time period. Total productive maintenance (TPM) is the broadest type of maintenance that targets more than just the assets that need to be maintained. There are many other types of maintenance that work well for all types of organizations, from small stores drowning in paperwork orders to data-based business operations, for which predictive maintenance is a reality. Preventive maintenance is commonly used to maintain a facility's assets, such as HVAC machines, and reactive maintenance is primarily used to maintain areas of a facility in good operating condition, such as painting walls.

To understand what types of maintenance to implement, you must know what types you are currently using and what your maintenance objectives are. Reactive maintenance is commonly used to respond to a tenant's request to repair items in their units, and preventive maintenance is used to regularly inspect and replace filters on essential assets, such as an HVAC machine. It's not uncommon for emergency maintenance costs to cost twice as much as a preventive maintenance strategy, since the response is very urgent and the nature of maintenance is often extensive. Among all the types of maintenance mentioned above, condition-based maintenance is the most complicated to implement.
