Abstract
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 manufacturer over a time period, such as an operating shift. The running shovel life score is increased 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.
