Types of Maintenance

Maintenance is an activity that prevents equipment failures. It is the opposite of the old adage “if it’s not broken, don’t fix it”.수원운전연수Maintenance is an activity that prevents equipment failures. It is the opposite of the old adage “if it’s not broken, don’t fix it”.


Most machines cost a small fortune to begin with, so it only makes sense that businesses want to maintain their assets for as long as possible. Good maintenance practices maximize asset utilization and positively impact business ROI through efficiency and consistency.

Preventive Maintenance

Preventive maintenance involves proactively inspecting, cleaning and servicing equipment to identify potential issues. This helps organizations minimize downtime and repair costs. It also increases equipment life span compared to reactive maintenance, which occurs after equipment starts breaking down.

The best preventive maintenance plans include a detailed schedule with inspection frequency, servicing requirements and repair protocols for each piece of equipment. These plans should also cover all safety procedures and specific equipment details, such as the type of lubricant to use or the dimensions of an equipment part. The plan should also include documentation of all maintenance work, including the description of the procedure, the date it was conducted and the signature and certification number of the technician who performed the task.

Another important aspect of PM is that it should be updated regularly to reflect changes in equipment and work processes. This will help keep your personnel motivated and ensure that all PM tasks are relevant. PM tasks that are no longer necessary might have become redundant due to newer equipment, better parts or more efficient ways of working.

수원운전연수 Many maintenance teams struggle to execute preventive maintenance effectively. One reason for this is that the tasks are often time-consuming. One way to address this issue is to switch to a digital, mobile-enabled Knowledge Management system that allows maintenance personnel to access all the information they need quickly and easily.

Corrective Maintenance

If you’ve ever fixed a broken washing machine or dishwasher, you engaged in corrective maintenance. The process restores equipment to working order by troubleshooting, disassembling, adjusting, repairing, replacing, and realigning components and sub-assemblies. It also includes lubrication, calibration, contamination control, and testing.

Some unscheduled corrective maintenance work is necessary when monitoring reveals potential faults, such as a deterioration in condition or an operating anomaly that suggests imminent failure. Prompt action minimizes repair costs and downtime.

Unlike preventive maintenance, where the goal is to find issues before they become full-blown breakdowns, corrective maintenance focuses on resolving breakdowns as they occur. It’s a necessary strategy for companies that can’t afford to invest resources in creating a comprehensive PM program for every asset or machine.

Ideally, the most effective approach to corrective maintenance is to use both preventive and condition-based maintenance strategies in tandem to minimize downtime and repair costs. A robust CMMS can support both by making it easy for employees to identify an issue and submit a work request, while allowing maintenance technicians to check status and prioritize tasks in the field. A mobile CMMS offers the additional benefit of providing a collaborative platform that lets all team members communicate and share files, regardless of their location in the building. This helps reduce the time it takes to get a task approved, assigned, and resolved.

Asset Management

Asset management (AM) is the process of acquiring, maintaining and disposing of assets in a way that provides maximum return on investment. It also includes identifying risks and optimizing assets. There are several types of AM, including financial, physical and infrastructure.

The financial form of AM involves pooling the savings from individuals and companies to invest in assets like stocks, mutual funds and exchange-traded funds. The sector is highly regulated to ensure that investments are made ethically and in the best interests of investors.

A physical form of AM involves ensuring that an organization’s fixed assets (also known as property, plant and equipment) are well-maintained. This can include appliances, sanitary installations, office supplies and large machinery. It can also include infrastructure, such as roads, railways and electricity grids.

Enterprise asset management (EAM) software is used to manage the tracking and maintenance of a company’s physical assets. EAM software can track data on the condition of the assets and their locations, as well as provide reports on the performance of each asset in an organization’s portfolio. Popular EAM software programs include Ivanti, GoCodes and Asset Panda.

Another type of AM is engineering asset management, which refers to the management of more complex physical assets. These assets require specialist engineering methods to manage their life cycles and maximize value for the owner while keeping risk to a minimum. This type of AM requires specialized knowledge in fields like engineering, finance and accounting.


Inspections are critical examinations of a work area or equipment to identify and record conditions that may result in incidents, accidents, injuries or illnesses. Inspections can be part of preventive maintenance procedures or hazard control programs and are often required by workplace laws, regulations and standards. Generally, inspections should be conducted by trained workers and health and safety committee members.

For example, a home inspector checks the condition of a home’s electrical system. The inspector looks at the size of the main breaker to ensure it’s adequate for the house’s needs and the quality of wiring, checking that copper wires are used instead of aluminum and there isn’t any rust in the breaker box. The inspector also tests all wall outlets and light switches to make sure they are working properly.

Use checklists for on-the-spot recording of inspection details. However, be careful not to become so intent on recording every item on the checklist that other potentially hazardous conditions are missed. It’s also a good idea to have a member of the inspection team accompany supervisors to provide them with a first-hand look at work operations and to encourage supervisors to correct any hazardous conditions they notice. This approach reduces the risk of a supervisor misinterpreting an inspection report as criticism or resentment. It also helps the inspection team quickly resolve issues and keep their records clear of erroneous items.
