METHOD OF ESTIMATING LIFE EXPECTANCY OF ELECTRIC MINING SHOVELS BASED ON CUMULATIVE DIPPER LOADS

摘要

An operational life of an electric mining shovel is determined by monitoring cumulative dipper loading, both above and below a benchmark weight set by a manufacture r over a time period, such as an operating shift. The running shovel life score is increas ed when a dipper payload is less than the benchmark weight and increased when the dipper payload is greater than the benchmark weight. The shovel life may be tracked over a time period such as an operator's shift or a thirty day period. The shovel life is used by the operator to operate the shovel in a manner consistent with the manufacturer's ratings.
