Equipment selection - QueensMineDesignWiki

The equipment life cycle (useful life of equipment) is an important metric to consider as it establishes the estimated time a machine will have fulfilled its production and economic targets, and should be replaced. This factor may not apply to all pieces of equipment in a mining operation, as some will possess service lives greater than the mine life; however, most mobile equipment fleets have ...

Equipment Lifecycle Management - Cat Caterpillar

When equipment downtime is unscheduled, costs go up, productivity and efficiency go down, and component life suffers. Through regular monitoring of machine conditions, mines can adopt a more proactive approach to maintenance and repair. Equipment health data is a key contributor to condition monitoring. But sorting through all that data can be ...

Mining Fleet Achieves 100,000 Hours and Beyond Cat ...

As mining equipment gets older, its availability tends to decrease. However, this has not been the case for the haul truck fleet operating at Sierrita—due in large part to the fact that the mine has a world-class PM program, with processes and procedures in place to support its equipment fleet. “The truck fleet was new, the maintenance philosophy was not,” says Puckett. “We were ...

Three Ways to Estimate Remaining Useful Life for ...

Remaining useful life (RUL) is the length of time a machine is likely to operate before it requires repair or replacement. By taking RUL into account, engineers can schedule maintenance, optimize operating efficiency, and avoid unplanned downtime. For this reason, estimating RUL is a top priority in predictive maintenance programs.

05/08/2014  The last thing you want on a mining site is non-working equipment. Improper maintenance will shorten the lifespan of machinery, cause it to breakdown frequently, require costly repairs, and slow down your operations. Also, there are workers who die each year due to heavy machinery accidents — often caused by non-maintained equipment and improper training. Following these tips might help ...

Major Equipment Life-cycle Cost Analysis

Equipment life-cycle cost analysis (LCCA) is typically used as one component of the equipment fleet management process and allows the fleet manager to make equipment repair, replacement, and retention decisions on the basis of a given piece of equipment’s economic life. The objective of this research is to develop a robust method that permits equipment f leet managers to maximize the cost ...
