Many different businesses require the use of equipment. It can help us with a variety of tasks in industries, including construction, IT, shipping, farming, and dozens of others. When you buy new equipment, whether it is a computer or heavy equipment parts, you want to get the most out of that equipment. A big part of ensuring you get the most value out of your equipment is implementing an appropriate equipment maintenance program to achieve optimal performance.

Why Equipment Maintenance is Important

Equipment maintenance includes the maintenance of various equipment types, such as heavy machinery, tools, vehicles, computer systems, etc.

So, let’s see why this is important for any business that uses equipment, whether light or heavy equipment:

1. Prevent Equipment Failure

Equipment failure can cost your business profits and better productivity. Imagine you have a client with a big order, and your equipment doesn’t work. You don’t want this to happen.

Proper equipment maintenance is key to achieving your business goals and extending asset life. If you have an effective maintenance program in place, you can minimize many equipment failure risks and costly repairs.

2. Increase Equipment Efficiency

Regular maintenance reduces equipment downtime and overall business efficiency. An equipment maintenance schedule helps you plan maintenance tasks more effectively and ensure your most important equipment is running smoothly and consistently.

This proactive maintenance will minimize unexpected equipment breakdowns and maximize your business’s operational efficiency.

3. Safety and Avoid Accidents

Maintenance is also important to ensure the safety of employees who use equipment and prevent accidents. By maintaining equipment properly, you can prevent equipment failure that can cause workplace accidents and injuries.

For example, working with heavy construction equipment can be a dangerous profession. While accidents such as falls are a common source of injury, equipment that isn’t working as expected can also be to blame. As a result, maintaining equipment also has the chance to reduce injuries on the job site.

4. Extend Equipment Life

If you have invested in expensive equipment, the last thing you want is for it to last only a short time. By performing proper maintenance practices to extend equipment life and and ensure the equipment will operate at its peak for a longer period of time before it begins to wear down.

Regular maintenance and inspections will help you identify potential issues early so maintenance managers can address them before they become major problems.

This will not only extend equipment life but also improve equipment performance and reliability.

5. Reduce Maintenance Costs

A well-planned maintenance management will reduce your maintenance costs and optimize resource allocation.

By doing preventive maintenance, you can avoid costly repairs and emergency repair services. A maintenance program ensures all maintenance tasks are done efficiently, reduces unnecessary expenses, and improves overall business financial health.

Types of Equipment Maintenance Strategies

Understanding the different types of maintenance is important if you want to ensure optimal equipment performance and prevent equipment failures.

Here, we break down four primary types of maintenance strategies, each with its own unique approach and benefits.

1. Reactive Maintenance

Reactive maintenance (also known as corrective maintenance, as the name says, is performed only when equipment breaks or malfunctions.

So, corrective is simply a reactive maintenance strategy that involves repairing or replacing faulty components to restore equipment functionality.

For instance, if a conveyor belt in a distribution center stops working, reactive maintenance would involve identifying the issue and fixing it promptly to minimize the downtime of the conveyor.

2. Preventive Maintenance

Preventive maintenance (or preventative maintenance) is a proactive approach that involves regularly scheduled inspections, cleaning, and servicing to address potential issues before they lead to equipment failure. This proactive maintenance strategy is designed to keep equipment running efficiently and extend its lifespan.

For example, in a manufacturing plant, preventive maintenance might include routine inspections and lubrication of machinery to prevent wear and tear.

This type of maintenance involves regular scheduled inspections, cleaning, and servicing. Preventive maintenance tasks may include routine inspections, lubrication, filter replacements, and calibration.

3. Predictive Maintenance

Predictive maintenance, on the other side uses data and sensors to forecast possible failure of equipment and schedule appropriate maintenance only when necessary. This approach relies on technology to monitor equipment conditions and predict when maintenance should be performed in order to reduce downtime and maintenance costs.

An example of predictive maintenance is using vibration analysis to detect bearing wear in heavy machinery before it leads to equipment breakdown.

4. Condition-Based Maintenance

Condition-based maintenance is performed based on the actual condition of the equipment, using data and sensors to monitor its health. Maintenance tasks are carried out only when specific indicators show signs of declining performance or potential failure.

An example of condition-based maintenance is using oil analysis in construction equipment to determine when an oil change is necessary rather than following a fixed schedule.

5. Reliability-Centered Maintenance

Reliability-Centered Maintenance (RCM) is a process to determine the best maintenance strategy for a piece of equipment. This process looks at the functions of critical assets and the consequences of equipment failures.

The most critical assets are those that fail most often or can cause the most harm if they do. So RCM looks at performance, maintenance history, and operational context to identify potential failures, the root cause of each failure, the impact on the business critical functions, and select the best maintenance task for each failure mode.

To determine the impact of each failure mode on your business operations, this maintenance strategy uses failure modes and effects analysis (FMEA), Hazard and operability studies (HAZOPS), Fault tree analysis (FTA), etc.

Maintenance engineers and certified equipment managers are key to implementing RCM by using maintenance software and analytics to predict failures and schedule maintenance tasks.

By using RCM, you can have a better maintenance program that fits your operations and goals.

How to Implement an Equipment Maintenance Program?

One of the most important parts of maintenance management is to have in place a maintenance program. When you or your maintenance manager are working on such a program, include other people, such as maintenance technicians, to give suggestions.

Here are some important steps that will help you in developing such a program:

1. Inventory and Maintenance History

First, create a comprehensive inventory of all equipment your business uses. However, not all equipment is equally important for your business operations. So, I highly recommend classifying your equipment according to its importance in satisfying your customers. This is important for you because it will help you design an effective equipment maintenance management program.

When you have a list of your equipment and its importance, you can analyze the maintenance history based on your current practices for each piece. This will help you to clearly understand past equipment failures and then plan future maintenance strategies.

2. Analyse Technical Documentation

The second step is really important for your maintenance program, and I always recommend that maintenance managers conduct it. Why? The technical documentation contains the equipment manufacturer’s appropriate guidelines for the maintenance team.

These guidelines will help you in developing your equipment maintenance strategy and program.

3. Develop a Maintenance Strategy

The third step is to create an appropriate maintenance strategy based on the criticality (importance) of your equipment, the processes where it is used, and your business objectives.

Now, you must decide whether to apply preventive, predictive, or corrective maintenance strategies to different equipment you are using based on the importance.

4. Develop a Maintenance Checklist for Each Equipment

Maintenance checklists are really beneficial tools for the implementation of appropriate maintenance strategies. For each piece of equipment and type of maintenance, the maintenance checklist will summarize what will need to be done in a step-by-step approach.

5. Establish a Maintenance Schedule

Now, when you have a strategy and maintenance checklist for each piece of equipment, you can develop a detailed maintenance schedule to ensure timely servicing. This schedule should outline the frequency (how much time it will be executed in a specific period of time) of routine maintenance and inspections to minimize equipment downtime.

6. Assign Maintenance Tasks

How can you ensure that everything will be implemented if there is no responsibility assigned to your team members who will work on maintenance?

So, now you must assign specific tasks to qualified personnel, such as maintenance technicians or a certified equipment manager.

7. Review and Update the Program

The last step is to regularly review and update your maintenance program to incorporate new insights and improvements. This continuous improvement process will help you adapt to changes and improve your equipment efficiency.

Roles and Responsibilities in Equipment Maintenance

Maintenance is not a one-person job; I have seen some companies give it to one person. It’s a function that can make or break your business if it depends on the equipment to meet your customers.

A well-coordinated maintenance team, including maintenance technicians, mechanics, managers, and engineers, plays a crucial role in ensuring equipment safety and efficiency by addressing any issues that may arise.

Here are the roles and responsibilities when it comes to maintenance management:

Maintenance Managers

A maintenance manager is responsible for managing and executing the maintenance management program and ensuring all maintenance strategies are followed. They plan and implement the equipment maintenance program, coordinate with the maintenance team, and manage maintenance costs.

Equipment Operators

Equipment operators report equipment issues and do routine maintenance tasks. They use the equipment daily and are the ones who know the equipment best.

So, they are the first to notice any equipment performance problems and should notify the maintenance team or maintenance manager.

Als,o by doing regular checks and maintenance daily, equipment operators prevent equipment breakdowns and ensure workplace safety.

Maintenance Personnel

Maintenance personnel do maintenance tasks and report any issues that arise. They do routine inspections, preventive maintenance and corrective maintenance to ensure equipment runs smoothly.

Their role is crucial to minimize equipment downtime in the future and ensure maintenance schedules are followed.

Maintenance Engineers

Maintenance engineers design and implement equipment-specific maintenance procedures to improve equipment performance and reliability. They use data and analytics that must be included in the maintenance strategy to forecast equipment failure and schedule tasks accordingly.

Their expertise in maintenance management and the use of maintenance software tools help in optimizing maintenance efforts and improving operational efficiency.

Remember that equipment maintenance certifications are crucial to ensure you will have a skilled maintenance team. Such certifications will improve skills and knowledge in the maintenance field. So, look at some specific certification programs from organizations like the Association of Equipment Management Professionals. This maintenance association offers some valuable certification programs, such as the Equipment Management Specialist (EMS), Certified Equipment Manager (CEM), and Certified Equipment Support Professional(CESP).

Maintenance Metrics and KPIs

To ensure continuous improvement of your equipment maintenance management processes, you must ensure you measure and analyse several important key performance indicators. Let’s look at some of the most important KPIs related to equipment maintenance:

1. Mean Time Between Failures (MTBF)

Mean Time Between Failures (MTBF) is a KPI that measures the average time between equipment failures. This KPI will help your maintenance manager to better understand equipment reliability. It is a critical metric in equipment maintenance management, particularly for preventive maintenance.

You can calculate MTBF if you divide the total operating time in the analyzed period of your piece of equipment by the number of failures in the same period of time:

Let’s look at one example. If a piece of equipment operates for 1,000 hours and experiences five failures, the MTBF then would be 200 hours.

2. Mean Time to Repair (MTTR)

Mean Time to Repair (MTTR) measures the average time required to repair equipment after a failure.

You can calculate the Mean Time to Repair (MTTR) by dividing the total repair time in the analyzed period of time by the number of repairs conducted in the same period.

If the total repair time for equipment is 50 hours after 10 repairs, the MTTR would be 5 hours. So, according to this metric, you spend 5 hours on average on repairing your equipment.

Overall Equipment Effectiveness (OEE)

Overall Equipment Effectiveness (OEE) measures the overall efficiency of equipment, combining performance, availability, and quality into a single metric.

To calculate OEE, you must find the availability rate, performance rate, and quality rate:

When you know availability, performance, and quality rates, you can calculate Overall Equipment Effectiveness by multiplying all three rates.

Let’s say that the availability rate is 90%, performance is 85%, and quality is 95%; the OEE would be 72.68%. This means that the equipment in 100 hours as a total operating time produces results only 72.68 hours. The rest, more than 27 hours, are losses.

Maintenance Cost as a Percentage of Replacement Asset Value (MC/RAV)

Maintenance Cost as a Percentage of Replacement Asset Value (MCAR) is another equipment maintenance KPI that measures the cost of maintenance relative to the replacement asset value. Using MC/RAV helps you to compare the cost to replace existing equipment (assets) with new equipment with the same performance against the total maintenance cost including materials, labor, and services expected to be used annually.

You can calculate Maintenance Cost as a Percentage of Replacement Asset Value (MCAR) if you divide total annual maintenance costs (MC) by the Replacement Asset Value (RAV):

For example, if your total maintenance costs are $20,000 per year for the specific equipment, and the replacement asset value is $400,000, the MCAR would be 5%. This metric can help you control the costs for maintenance, decide when to replace the equipment when the costs start to increase, and ensure that your maintenance tasks are aligned with your budget restrictions.
