EXECUTIVE SUMMARYThere are different types of machinery tools and equipment’s which are been used inengineering companies. Each of them requires maintenance so that it works properly and forlong time. Every organisation highly focuses on maintaining their physical assets so thatefficiency is not impacted. The report has described about maintenance strategy of Elphinstoneengineering and how they are able to maintain various assets. The company have made somechanges in their strategy by implementing principle of lean management.

INTRODUCTIONIn a company asset are the most important part that can be easily converted into cash.They are classified into two types that is tangible and non tangible. The overall asset of companyreflects its market value. It is essential to maintain those assets so that it can be used for longterm (Seecharan, Labib and Jardine, 2018). In order to do so, a proper maintenance strategy isrequired which helps in evaluating and enhancing efficiency of asset. Besides this, in strategiesdifferent types of risks are identified and mitigated. Furthermore, it enables in improvingefficiency of asset by making changes in its process. However, sometimes changes are requiredin strategies so that it decreases cost, time and resources of maintenance. This report will give aninsight on maintenance strategy of Elphinstone engineering. It will discuss about lean principlesfollowed by firm in strategy. The company is engaged in manufacturing trailers and equipment’sof trucks. of different types of machinery tools used in Elphinstone engineering. It was foundedin 1976 by Graeme Elphinstone.QUESTION 11) Construct a process flow diagram and establish asset inventory in Elphinstone engineeringDefinition of process flow diagram-A process flow diagram indicates how overall machinerytools works. It briefly describes relationship between various equipment’s (Wakiru and et.al.,2018). There are many steps included in it which defines how machine works. PFD are usuallyused in engineering companies. this gives them an overview about from where process starts andend and in which direction it moves.Process flow in Elphinstone engineeringIn Elphinstone engineering there are various types of machinery tools used. it is used inmanufacturing parts of heavy vehicles and also its components. They have to maintain them inorder to ensure its efficiency. For this, maintenance department ensure that they are properlymaintained. It helps in smooth running of functioning of asset within organisation. It has beenfound that most of machinery used by company is gear box, electro motor, etc. The process flowat Elphinstone engineering is described below :-AssetsAreas of Storage1.

Processing MachineFactoryFrom above mentioned asset, gear box is taken. this is because it is an essential tool forcompany that is used in machines and manufacturing heavy vehicles. Moreover, Elphinstoneengineering also produced gear box for vehicles as well. So, maintaining this asset is very crucialfor organisation.2Illustration1: process flow diagram
2) Detail asset operating characteristics and production policyGearbox consist of spur Gear whose teeth are straight and parallel to shaft axis. Ittransmits power and motion between two parallel rotating shafts. It also consists of helical gearwith twisted oblique to the gear axis and has higher strength then spur gear. It also consists ofannular gear that meshes with the external gear. It also has a pair of gears that connects twoshafts with axis intersect. Helical gear transmit power from one shaft to another and it is used toreduce speed or increase speed. All these gears work together for smooth running of a vehicles.3) Assemble identified maintenance task in unit life planUnit life planItemtimingOn-line oroff-linefrequencyTime andlabourInitialmaintenance actionExpectedfrequencyTime andlabourRubberliningTouch andvisualinspectionoff6 moths2 fittersand 2 daysIn siturepairOverall 2years2 days and2 fittersSteelcasingStatutoryinspectionoff1.5 years2 fitters, 1inspectorand 2 daysJointsrequiredOverall 5years2 days and2 fittersgearboxgreasingSPM trendmonitoringon1.5monthsFewminutesand 1inspectorIf requiredreplaceboxOverall 4yearsFew hoursand 2fittersGearboxbearingFixed timelube ratingon1.5months----GearsMonitoring,lubricationon1.5monthsFewminutesand 1inspectorIf requiredreplaceboxNo ideaFew hoursand 2fittersglandVisualinspectionon2 mothsFewminutesAdjustglandsOver all 6months-3
