Before I proceed in the processes of maintenance, it is important to identify some of the equipment and machinery on any project and construction site. They are listed and identified below:

Definition of Maintenance

At a car dealership, the person who sells the car is the hero, and also gets the commission. But if the mechanics don't service that car well, the customer won't return. Roger Staubach

We will be looking at the importance and processes of maintenance of our day to day usage of Equipment's Machineries and Tools.

Maintenance is defined as any engineering activity necessary for retaining or restoring a piece of equipment, machine, or system to the specified operable condition to achieve its maximum usefulness.

There is a life span for every equipment and this equipment must be put in to use maximally within this time framework to justify the fund expended on its acquisition.

A broken down equipment rapidly but to keep the equipment running at high capacity and to produce quality products at lowest cost possible .The Objectives of Maintenance is a priority one which will ensure the availability of functional and efficient machinery and equipment in an organization.

TYPES OF MAINTENANCE

Preventive MaintenanceCorrective MaintenanceBreakdown MaintenanceTurn-Around MaintenancePeriodic Maintenance

PREVENTIVE MAINTENANCE

Preventive Maintenance is defined as an art or method of carrying out maintenance work on equipment to prevent breakdown of the equipment and cause down time.It is a systematic inspection, detection, correction and prevention of incipient failures before they become actual or major failures.

Preventive maintenance work are to be carried out at regular interval, these includes the followings but not limited to:Adjustment of Crawler Machines track/slippersLubricating/greasing of trucks/equipment turning pointsRetightening of loosen bolts and nuts on trucks/equipmentsChecking end-play of moving /rotary parts on trucks/equipmentsChecking of the trucks brake linings for wear

Preventive Maintenance ..Contd.

Do It Yourselves (DIY) Tips: Check tire air pressure daily Check engine oil level daily Check battery terminal clips and electrolyte Check brake and power steering fluid level Check radiator water levelBe familiar with signs and symbols Observe simple safety precautions: Batterys positive terminal clip must first be disconnected before any engine repair. Equipments, trucks and machines must be properly supported with axle stand before commencement of repair work.

CORRECTIVE MAINTENANCE

Corrective Maintenance is any engineering activities undertaken to detect, isolate, and rectify a fault so that the failed equipment, machine, or system can be restored to its normal operable state.

Fuel filters and air filters can be replaced before the scheduled hour/mileage to correct failure in an engine when the equipment is working at the extreme dusty environment/condition.Hydraulic Hose, Fuel Hose or Pipe may got busted or broken due to prolong use or under extreme temperature/weather condition.

BREAKDOWN MAINTENANCE

Breakdown Maintenance is defined as the repairs or replacement process carried out on a failed machine. It is an activity usually carried out in order to bring the machine back to its functional state or working order. It is also defined as maintenance activity performed on a broken down machine to restore it to working order to prevent down time.

BREAKDOWN MAINTENANCE CONTD

In carrying out breakdown maintenance which ultimately requires replacement of spare parts, emphasis should be made in ensuring that Bad, malfunctioning and unserviceable parts are replaced with ORIGINAL not as SUB-STANDARD parts will prevent the equipment from performing to its full capacityThe fund spent in replacing fake or low quality parts continually will be higher than the initial cost of the quality one.

TURN-AROUND MAINTENANCE

Turn-Around Maintenance is a planned periodic shut-down either partial or total of process plant or machine in an outfit to perform maintenance, repair and overhaul (MRO) operations and to inspect, test and replace process materials and equipment for effective performance.It is planned one or two years ahead to allow for adequate preparations because of the fund involved in carrying it out.

PERIODIC MAINTENANCE

Periodic Maintenance is defined as the significant activities carried out regularly according to predetermined schedule or Original Equipment Manufacturers (OEM) specifications to maintain the condition or operational status of an equipment, machine, plant, or system. Some systems in the equipment or machine requires attention after a specific time or period in term of the number of hours the equipment has worked or the months that it has being put in to use or the speed it has cover in distance.

SAFETY EQUIPMENTS

SAFETY CAUTIONS Safety is any precaution taken to prevent accidents or dangers Always make use of safety signsLack of or flagrant disregard to safety rules and norms results in injuries, accidents or even death.Check for sharp edges.If the load is wet or slippery, wipe if off.Lift with your legs and not back.Squat down close to the load, keep your back straight; lift slowly with leg power.Use material handling equipment whenever possible. When properly used, it can save a lot of manual effort.

CONCLUSION

Maintenance is the work of everybody, you dont need to consult a technician before you do some minor maintenance work on your items be it home appliances or other objects we use in our day to day activities.We are all encourage to imbibe maintenance culture as this will go a long way in keeping our items, equipments and machines functioning and save us from incurring avoidable expenses.

People say writing is really hard. That's very unfair to those who are doing real jobs. People who work in the fields or fix roofs, engineers, or car mechanics. I think lying on your back working under an oily car, that's a job.
