MAINTENANCE SYSTEM FOR HEAVY EARTH MOVING EQUIPMENT

Abstract

Heavy earth moving equipment’s are critical for completion of any developmental projects. Dams, schools, bridges or any mining related initiations are part of these infrastructure development projects. Usually the delays are due to the inefficient and ineffective maintenance procedures of the heavy earth moving equipment’s. Poor record keeping and un-systemized maintenance procedures leads to reducing the machine effective life cycle. To avoid catastrophic losses in production and, market share, a maintenance model for such equipment is developed. Heavy equipment availability is mandatory on site. Their movement is critical and usually limited. The data collected includes both manufacturer and operator requirement. Usually such equipment is treated as normal machine irrespective of the rough environment it works in. The analysis includes segregation, Pareto analysis and Five Why analysis. A dedicated maintenance model is proposed which includes checklist and proper maintenance schedule.
