Abstract
This degree work has been dedicated to maintenance management focused on operational
reliability in HITACHI EH 5000 320T electric trucks for the open pit mining company
Cerrejón. For the development of the present work, the operating parameters and the
current maintenance indicators of the HITACHI EH 5000 DE 320 equipment were
described. Subsequently, the criticality analysis, root cause, Pareto diagram of the failures
and the mode and effect analysis were carried out. of the fault. Finally, the maintenance
processes and standard work procedures are established. The development of the work
was framed in a study period of one calendar year for this case the year 2020, time that
allowed taking relevant data for the analysis and subsequently obtaining the results. The
reliability of the CAM 320T fleet was determined to average 98.3%, that the TPPR is 3.42
h / failure and that the TPEF is 64.47 h / failure. Applying maintenance management to the
CAM 320 fleet made it possible to identify frequent failures and analyze them in detail to
use continuous improvement tools and improve the processes that were standardized
